Solve: 2|x 7|−4 ≥ 0 express the answer in set-builder notation.
The correct answer for the given inequality is {x | x ≤ -9 or x ≥ -5}.
What is inequality?Inequality is a statement shows greater the, greater then equal to, less then,less then equal to between two algebraic expressions.
To solve an absolute inequality, first step is to isolate absolute value expression.
Hence remove -4 from the left side. So, add 4 to each sides of the inequality.
2|x + 7|−4 ≥ 0
2|x + 7|−4 +4≥ 0 +4
2|x + 7| ≥ 4 Combine the like terms.
Divide each sides by 2.
[tex]\dfrac{2|x + 7| }{2} \geq \dfrac{4}{2}[/tex]
|x + 7| ≥2
Next step is to remove the absolute value sign. So,
x + 7≥2 and x+7≤-2.
x≥2-7 and x≤-2-7
x≥-5 and x≤-9
So, the correct choice is {x | x ≤ -9 or x ≥ -5}.

Mary wants to buy a sewing machine, she can buy it for $315 cash, or on hire purchase for $25 down payment and 12 monthly instalments of $27. 50. How much more will Mary have to pay on hire purchase?
Answer:
She will pay $40 more.
Step-by-step explanation:
I used the equation y=27.50x + 25 to find this out and made x = 12 to represent how many months she is paying.
now putting x into the equation, y = 27.50(12) + 25
First i did the multiplication, 27.50 x 12 = $330.
Then I added 25 to 330 for the down payment, 330 + 25 = 355
I then did 355 - 315 to find out how much more you would pay,
355 - 315 = $40

Find the total amount
$16.000 at 14% compounded
semiannually for 2 years
Answer:
The answer would be 20.97273616 or (rounded to the nearest cent) would be $20.97
Step-by-step explanation:
The reason for this is that the formula for compounded interest is [tex]A=P(1+\frac{r}{n})^\frac{t}{n}[/tex] where A is the total amount, P is the initial amount, r is the growth factor or the percent, n is the number of compounding periods, and t is the time. You would substitute P for 16, r for 0.14 (14%), n for 2 as it compounded semiannually so it for every 6 months instead of 1 year (annual) so is compounded 2 times per year, and t for 2. And just solve the equation and you get that A is equal to 20.97273616 but since we are talking about money( only round if asked) then it would be 20.97.

Which expression is equivalent to 3
5v ?
Answer:
x ^5/3 y ^1/3 (the second option listed)
Step-by-step explanation:
So without even solving the expression, you can find the correct option. If you're finding the cube root (or really any square root), you know it will be less than your original number (unless you are working with imaginary numbers, but you aren't).
So, if you are finding the cube root of an expression, you're finding the cube root of each number separately.
You wouldn't be cubing y, you would be finding the cube root. You wouldn't be leaving y the same, you are finding the cube root.
This means that without even solving (which I will explain),
the correct option is the second one on the screen.
Here's how to actually solve the equation:
So, if we are finding the cube root of a variable with an exponent, we can divide that exponent by 3 (because it is a cube root).
When we have a square root, you know that we are breaking down each number/variable into an even exponent to solve the expression. When taking the square root of an even exponent, such as 4, you would divide by 2.
This same strategy applies to cube roots. You are dividing the exponent of both variables by 3.
[remember: the exponent of a variable without an exponent is essentially an invisible exponent of 1.]
use the image to match the arc/angle measure.
(there is one more option that i wasn’t able to get in the photo it is 67°
Answer:
The following measurements are:
[tex]m\angle{STR}=23^\circ[/tex] (Option #4)
[tex]m{QT}=142^\circ[/tex] (Option #7)
[tex]mST=134^\circ[/tex] (Option #5)
[tex]mRQ=38^\circ[/tex] (Option #2)
Step-by-step explanation:
To begin, we can find the measure of [tex]\angle{STR}[/tex] by applying the inscribed angle theorem: an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
Since the intercepted arc (RS) is 46 degrees, we have:
[tex]46=2\theta\\23=\theta[/tex]
Next, we can find the measure of arc QT using the same theorem. So,
[tex]QT=2(71)\\QT=142[/tex]
Notice that the chord RT is actually a diameter. From the theorem about the inscribed angle including a diameter, we know that the intercepted arc will have a measure of [tex]180^\circ[/tex]. Since the arc ST is part of the arc RST, and we know RS is [tex]46^\circ[/tex], we can set up and solve this equation:
[tex]RST = RS + ST\\180 = 46 + ST\\134 = ST[/tex]
We can use the same idea to find RQ. We know that RQT is [tex]180^\circ[/tex] and QT is [tex]142^\circ[/tex], so:
[tex]RQT = RQ + QT\\180 = RQ + 142\\38 = RQ[/tex]
A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 4500 seats. The students left 3105 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?
[tex]\bull[/tex]Total number of seats in theatre = 4500
[tex]\bull[/tex]Total number of seats left vacant = 3105
Solution:-[tex]\longrightarrow[/tex]Number of seats occupied = Total number of seats in theatre - Total number of seats left vacant
[tex]\longrightarrow[/tex]Number of seats occupied
[tex]\quad[/tex]= 4500 - 3105
[tex]\longrightarrow[/tex] 1395
[tex]\\[/tex]
Now,
[tex]\begin{gathered}\bull \sf Percentage \:of \:seats \:filled = \frac{Seats \: filled \: by \:6th \:grader }{Total \:number \:of \:seats} \times 100 \% \\\end{gathered} [/tex]
[tex]\begin{gathered}\bull \sf Percentage \: of \:seats \: filled = \frac{1395}{45\cancel{00}} \times \cancel{100} \% \\\end{gathered} [/tex]
[tex]\begin{gathered}\implies\quad \sf \frac{1395}{45} \% \\\end{gathered} [/tex]
[tex]\begin{gathered}\implies\quad \sf 31 \% \\\end{gathered} [/tex]
[tex]\longrightarrow[/tex]Thus , 31 % of seats in the theater were filled by the 6th graders on the trip

Let f(x)= x(2x-3)/(x+2)x. Find the domain, vertical and horizontal asymptote
Step-by-step explanation:
Domain of a rational function is everywhere except where we set vertical asymptotes. or removable discontinues
Here, we have
[tex] \frac{x(2x - 3)}{(x + 2)x} [/tex]
First, notice we have x in both the numerator and denomiator so we have a removable discounties at x.
Since, we don't want x to be 0,
We have a removable discontinuity at x=0
Now, we have
[tex] \frac{2x - 3}{x + 2} [/tex]
We don't want the denomiator be zero because we can't divide by zero.
so
[tex]x + 2 = 0[/tex]
[tex]x = - 2[/tex]
So our domain is
All Real Numbers except-2 and 0.
The vertical asymptors is x=-2.
To find the horinzontal asymptote, notice how the numerator and denomator have the same degree. So this mean we will have a horinzontal asymptoe of
The leading coeffixent of the numerator/ the leading coefficent of the denomiator.
So that becomes
[tex] \frac{2}{1} = 2[/tex]
So we have a horinzontal asymptofe of 2

Step-by-step explanation:
7) Volume of the shape = Volume of triangular prism - volume of cylinder
Triangular prism:
[tex]\boxed{ \text{Volume of triangular prism = base area * h }}[/tex]
b = 6 ft & height of the triangle = 5 ft
[tex]\sf Base \ area = \dfrac{1}{2}* 6* 5[/tex]
= 3*5
= 15 ft²
Volume of prism = 15 * 4
= 60 ft³
Cylinder:
r = 2÷2 = 1 ft & h = 4 ft
Volume of cylinder = 3.14 * 1 * 1 * 4
= 12.56 ft³
Volume of the shape = 60 - 12.56
= 47.44 ft³
8) Volume = Volume of Pyramid - Volume of cone
[tex]\boxed{\text{Volume of the Pyramid = base area * h} }[/tex]
[tex]\text {base area = length * width}\\\\\\[/tex]
= 9 * 9
= 81 m²
Volume of Pyramid = 81 * 8
= 648 m³
[tex]\boxed{ \text{Volume of cone = \dfrac{1}{3} \pi r^{2}h}}[/tex][tex]\boxed{ \text{Volume of cone = $\dfrac{1}{3} \pi r^{2}h$}}[/tex]
r = diameter ÷ 2 = 6÷2
r = 3 m & h = 8 m
[tex]\text{ Volume of cone =$\dfrac{1}{3}*3.14* 3*3*8$}[/tex]
= 3.14 * 3 * 8
= 75.36 m³
Volume of the shape = 648 - 75.36
= 572.64 m³
9) Volume of the shape = volume of cylinder + volume of cone
Cylinder:
h = 7 in ; r = 3
[tex]\boxed{\text{Volume of cylinder =$ \pi r^{2}h$}}[/tex]
[tex]=\dfrac{22}{7}*3*3*7[/tex]
= 22 *3 * 3
= 198 in³
Cone:
r = 3 in & h = 4 in
[tex]\text{Volume of cone = $ \dfrac{1}{3}*3.14*3*3*4$}[/tex]
= 3.14 * 3 * 4
= 37.68 in³
Volume of the shape = 198 + 37.68
= 235.68 in³
10) Volume of the shape = Volume of outer cyliner - volume of inner cylinder
Volume of outer cylinder:
R = 9 m & h = 3 m
Volume of outer cylinder = 3.14 * 9 * 9 * 3
= 763.02 m³
Volume of inner cylinder:
r = 5 m & h = 3 m
Volume of inner cylinder = 3.14 * 5 * 5 * 3
= 235.5 m³
Volume of the shape = 763.02 - 235.5
= 527.52 m³
At a movie theater, the manager announces that a free ticket will be given to the first person in line whose birthday is the same as someone in line who has already bought a ticket. You have the option of getting in line at any time. Assuming that you don't know anyone else's birthday, and that birthdays are uniformly distributed throughout a 365-day year, what position in line gives you the best chance of being the first duplicate birthday?
please explain how you got this answer. Thank you!
The best chance is an illustration of probability
The 21st position in line gives you the best chance of being the first duplicate birthday
How to determine the best position?
Assume you are in the nth position, the probability of getting a free ticket is:
P(n) = P'(first n - 1 people share a birthday) * P(birthday with first n -1 people)
Mathematically, the above can be represented as:
P(n) = [365/365 * 364/365 * 363/365 * ... * (365 - (n -2))/365] * [(n -1)/365]
Such that: n [tex]\le[/tex] 365
When simplified, the equation becomes
p(n)/p(n+1) = 365/(366 - n) * (n - 1)/n
Where
p(n)/p(n+1) > 1
So, we have:
365/(366 - n) * (n - 1)/n > 1
Evaluate the product
(365n -365)/(366n - n²) > 1
Cross multiply
365n -365 > 366n - n²
Collect like terms
n² + 365n - 366n - 365 > 0
Evaluate the difference
n² - n - 365 > 0
Solve for n using a graphing calculator;
n > - 18.6 or n >19.6
n cannot be negative.
So, we have:
n > 19.6
Approximate to nearest integer
n > 20
The least integer value of n is:
n = 21
Hence, the 21st position in line gives you the best chance of being the first duplicate birthday

Directly solving the linear equations, we will see that:
a) x = -4b) x = 6c) x = 4/3d) x = 2.How to solve linear equations?
Let's start with the first one:
3 - x = 11 + x
First, move all the terms with x to the left side and the ones without to the right side:
-x -x = 11 - 3
-2x = 8
Now we divide both sides by -2
x = 8/-2 = -4
x = -4
2) 2x + 7 = 3x + 1
Same procedure:
2x - 3x = 1 - 7
-x = -6
x = -6/-1 = 6
x = 6
3) 8 - 2x = 4 + x
-2x - x = 4 - 8
-3x = -4
x = -4/-3 = 4/3
4) 4x + 2 = 2x + 6
4x - 2x = 6 - 2
2x = 4
x = 4/2 = 2
x = 2
So we solved all linear equations.
