Answer:
-5/3 - x = 5/6
-x = 5/6 +5/3
-x/-1 = (5/2)/-1
therefore x = -5/2
therefore -5/2 must be subtracted
Let U = {5, 10, 15, 20, 25, 30, 35, 40, 45, 50} A = {5, 10, 15, 20, 25} B = {25, 30, 35, 40, 45} C = {10, 20, 30, 40, 50} Find A∪B
Answer:
A∪B = {5, 10, 15, 20, 25, 30, 35, 40, 45}
Step-by-step explanation:
A = {5, 10, 15, 20, 25}
B = {25, 30, 35, 40, 45}
Find A∪B
There are 5 elements in set A
There are 5 elements in set B
A∪B is the combination of all the elements in set A and set B without repeating any
A∪B = {5, 10, 15, 20, 25, 30, 35, 40, 45}
A∪B has 9 elements in it
A ⋂ B = {25}
Jessi is making a clay tower for an art project. The tower has a rectangular base with an area of 36 cm2. She wants
to tower to be 10 cm high. What is the volume of clay that Jessi will use in her tower?
Answer:
360cm3
Step-by-step explanation:
To do this, you can multiply the base (l * w) by the height to determine the volume. This would be 36*10=360. Then remember that it is a 3 dimensional shape, so the valume is cubed.

Find the difference quotient of the exponential function, f(x) = e^x
Answer:
Step-by-step explanation:
The difference quotient in general looks like
[tex]\frac{f(x+h)-f(x)}{h}[/tex] Sometimes the symbol "delta x" [tex]\Delta x[/tex] is used instead of h.
For the exponential function, the difference quotient is
[tex]\frac{e^{x+h}-e^x}{h}[/tex]

You are currently working two jobs so that you can earn enough money to go to the beach for Spring Break Pollo Tropical
(x) and Jason's Deli (4). Pollo Tropical pays $8/hour and requires that you work at least 10 hours/week. Jason's Deli pays
$8.75/hour but does not allow students to work more than 20 hours per week. Due to commitments, at school, you can't
work more than 28 hours/week. Write the objective function and a system of inequalities to model this situation.
Answer:
First, let's define two variables:
x = number of hours that you work at the Pollo Tropical per week
y = number of hours that you work at Jason's Deli per week
Now, you want to get enough money to go to Spring Break, we do not know how much money we need for this, so let's suppose that you need M.
With the given information, we know that the weekly earnings are:
x*$8 + y*$8.75
We can define this as the objetive function, the one that says how much money you get as a function of x and y:
M(x, y) = x*$8 + y*$8.75
Now, we know that:
"Pollo Tropical requires that you work at least 10 hours per week"
Then:
x ≥ 10
"Jason's Deli does not allow students to work more than 20 hours per week."
y ≤ 20
"you can't work more than 28 hours/week."
x + y ≤ 28
Then we have:
M(x, y) = x*$8 + y*$8.75
And the system of inequalities is:
x ≥ 10
y ≤ 20
x + y ≤ 28

The cheerleader section is on the basketball court. Each row requires a section of floor that is 1 ¾ yards by 3 ⅓ yards. How many square yards of floor space are taken up by one row of cheerleaders? Help!
Answer:
The area of the floor space is equal to 5.83 sq yards.
Step-by-step explanation:
Given that,
Each row requires a section of floor that is 1 ¾ yards by 3 ⅓ yards.
We need to find how many square yards of floor space are taken up by one row of cheerleaders.
We know that, the area of a rectangle is given by :
A = lb
So,
[tex]A=\dfrac{7}{4}\times \dfrac{10}{3}\\\\A=5.83\ yards^2[/tex]
So, the area of the floor space is equal to 5.83 sq yards.
what is the volume of this triangular prism? the base is 12 ft the height is 6 ft and the bottom is 20 ft
Answer:
720 [tex]ft^3[/tex]
Step-by-step explanation:
Answer:
720 ft³
Step-by-step explanation:
Volume = Area Triangle times Length
Area triangle = 1/2(6x12) = 1/2(72) = 36 ft²
Volume = 36 ft² x 20 ft = 720 ft³
Volume = 720 ft³

Which values of x are solutions of the equation below
1/x-4 + x/x-2=2/x^2-6x+8
X=-1
X=-1,4
X=2
X=2,4
Answer:
x = 3.3 and -0.3
Step-by-step explanation:
Given the expression
1/x-4 + x/x-2=2/x^2-6x+8
Find the LCM
x-2+x(x-4)/(x-4)(x-2) = 2/x^2-6x+8
Since the denominator, are the same they cancels out
x +1 + x(x-4) = 2
x+1 + x²-4x = 2
x²-3x + 1 - 2 = 0
x² - 3x - 1 = 0
Factorize
x =3±√9+4/2
x =3±√13/2
x = 3±3.6/2
x= 6.6/2 and -0.6/2
x = 3.3 and -0.3

Answer:
81
Step-by-step explanation:
Find out the percentage of people who had mispriced item.
3/50 = 0.06
6% of people had mispriced items.
Find 6% of 1,350.
81
81 people would have mispriced items.
Answer:
81
Step-by-step explanation:
I did this by doing 1,350 ÷ 50, which gave me 27. I then did 27 times 3, the average amount of people with a mispriced item per 50 people, which gave me 81 as a result. And with that, I can conclude that you would expect there to be 81 people per day who have a mispriced item.
Need help with this, finding the length of the third side
Answer:
its sqrt (50)
Step-by-step explanation:
The triangle has a right angle, therefore we can use the Pythagorean theorem to find the hypotenuse. According to the theorem the sum of the squares of both other sides is equal to the square of the hypotenuse.
We have 5^2+5^2=c^2
=> 25+25=c^2
=> 50=c^2
Therefore c or the missing side is equal to sqrt(50)
A garage charges $55 per tire and $30 dollars per hour of labor. If you need two tries and it takes half an hour to install how much do you pay?
Answer:
$140
Step-by-step explanation:
First, we multiply the amount of tires by the price of the tire. $55 * 2 = $110.
Second, we multiply the amount of hours by the price of an hour of labor. They take half an hour, so we multiply $30 by 1/2.
1/2 * $30 = $15.
Finally, we add the cost of the tires and the labor together.
$110 + $15 = $125

Answer:
y=-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-(-3))/(3-(-4))
m=(-3+3)/(3+4)
m=0/7
m=0
y-y1=m(x-x1)
y-(-3)=0(x-(-4))
y+3=0(x+4)
y+3=0
y=0-3
y=-3

Shauna says that 2x2 + x - 12 is the same as (x+4)(x-3). Is
she correct? Are the two expressions equal? Explain your
answer.
Answer:
Shauna is incorrect, because (x + 4)(x - 3) is NOT equivalent to 2x² + x - 12
Step-by-step explanation:
Check if she is correct by expanding (x + 4)(x - 3), with FOIL:
(x + 4)(x - 3)
x² - 3x + 4x - 12
x² + x - 12
So, Shauna is incorrect, because the two expressions are not equal.
(x + 4)(x - 3) is equivalent to x² + x - 12, NOT 2x² + x - 12.
Answer:
No she's wrongTwo equations are unequal.Explained belowStep-by-step explanation:
[tex] \sf \rightarrowtail \: (x + 4)(x - 3) \\ \sf \rightarrowtail \: x(x - 3) + 4(x - 3) \\ \sf \rightarrowtail \: {x}^{2} - 3x + 4x - 12 \\ \sf \rightarrowtail \: {x}^{2} + x - 12 \cancel{ = } {2x}^{2} + x - 12[/tex]

Answer:
2. one angle is 108, and other is 72
3. x is 12
Step-by-step explanation:
the ratio is 3:2.
3x + 2x = 180
5x = 180
x = 36
36 x 3 = 108
36x 2 = 72
so that is why the two angles re 108and 72.
for the last question, 37 plus 41 plus x = 90
37 plus 41 is 78
90 - 78 = 12
so that is why x is 12.

The limit is x---->4-
The negative show that x approaches from the left
Now
As x approaches 4 from the left ... Means This number should be less than 4 (<4) but really close to 4.
Let's pick a Number
Say 3.99
Substitute this... You have
3.99/3.99-4
3.99/-0.01
If we choose x to be 3.999
we will have
3.999/-0.001
Notice the pattern... As x approaches 4 from the left... This limit will approach NEGATIVE INFINITY
Why?
As you approach 4 from the left... 3.9,3.99,3.999... You notice that the denominator becomes negative and EXTREMELY SMALL... and when you divide by an extremely small Number..... You'll get a relatively HUGE VALUE(You can try this... Use a calc... Divide any number of choice by a very small number... say.. 0.0000001.... You'll get a huge result
In our case... The denominator is negative... So it Will Approach a very Huge Negative Number
Hence
Answer.. X WILL APPROACH NEGATIVE INFINITY.
Vertical asymptotes are the zeroes of the denominator of a function
The denom. is x-4
Equate to zero to get the asymptote
x-4=0
x=4
Hence... There will be a vertical asymptote at x=4.
