Answer:
x > -7
Step-by-step explanation:
Step 1: Translate
Twice a number = 2x
Six more = + 6
At least = >
-8 = -8
Step 2: Write out inequality
2x + 6 > -8
Step 3: Solve
2x > - 14
x > -7
Which statements are true? Check all that apply
Which of the following is the set of all real number x such that x-2 < x-4?
If you subtract x from both sides, then you go from
x-2 < x-4
to
-2 < -4
which is a false statement. The value -2 is not smaller than -4. It's the other way around. I recommend looking at a number line to compare the two values.
This means that x-2 < x-4 is never true regardless of what x value you pick. So there are no solutions.
given:x+2<-5. choose the solution set.
Step-by-step explanation:
x+2<−5
Step 1: Subtract 2 from both sides.
x+2−2<−5−2
x<−7
Answer:
x<−7
.9 times what equals 1.5
Answer:
5/3
Step-by-step explanation:
x*0.9=1.5
x=15/9
x=5/3
Lets solve your question step by step:-
Given,
0.9*x = 1.5
0.9x = 1.5
=} 0.9x/0.9 = 1.5/0.9
x = 1.666667
So,
9 times 1.666667 (x) is 1.5

Substitute 2 for z in the given equation
[tex]4(2)^2 - 3(2) -4\\[/tex]
Follow the PEMDAS order of operations
[tex]\mathrm{Calculate\:exponents}\:\left(2\right)^2\::\quad 4\\=4\cdot \:4-3\left(2\right)-4\\\\\mathrm{Multiply\:and\:divide\:\left(left\:to\:right\right)}\:4\times\:4\::\quad 16\\=16-3\left(2\right)-4\\\\\mathrm{Multiply\:and\:divide\:\left(left\:to\:right\right)}\:3\left(2\right)\::\quad 6\\=16-6-4\\\\\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:16-6-4\::\quad 6[/tex]
Answer:
Step-by-step explanation:
Plug in z = 2 in the expression
4z² - 3z - 4 = 4*2² - 3*2 -4
= 4*4 - 6 - 4
= 16 - 6 - 4
= 10 - 4
= 6

Huda evaluated the expression below. Negative 3 (8 minus 5) squared minus (negative 7) = negative 3 (3) squared minus (negative 7) = negative 3 (9) minus (negative 7) = 27 minus (negative 7) = 34. What was Huda's error? Huda evaluated (3) squared incorrectly. Huda found the product of –3 and 9 as positive. Huda subtracted –7 from 27 incorrectly. Huda did not follow the order of operations.
Answer:
Huda found the product of –3 and 9 as positive.
Step-by-step explanation:
Given the expression and result below :
Huda evaluated the expression below. Negative 3 (8 minus 5) squared minus (negative 7) = negative 3 (3) squared minus (negative 7) = negative 3 (9) minus (negative 7) = 27 minus (negative 7) = 34
-3(8 - 5)² - (-7) =
Step 1:
- 3(3)² - (-7)
Step 2:
-3(9) - (-7)
Step 3:
27 - (-7) = 34 (error in the third step)
-3(9) = - 27
Hence,
-27 - (-7) = - 27 + 7 = - 20

For all integer values of x and constant k, if (x+6)(x+k)=x^2+14x+48, what is the value of k?
Answer:
8
Step-by-step explanation:
The product of terms on the left of the equal sign is ...
(x+6)(x+k) = x^2 +(6+k)x +6k
So, you have two clues to the value of k. The coefficient of x must match, and the constant must match.
6+k = 14 ⇒ k = 8
6k = 48 ⇒ k = 8
The value of k is 8.

Something that represent today’s culture ( sum that isn’t tech or social media)
It depends on which culture you're looking at to be honest. But in the current environment, one item that is fairly prevalent is the coronavirus facemask. You could say it symbolically represents the idea of trying to stay safe and it represents a new norm (that many may consider strange since people are used to seeing each other's faces).
What is the solution to the inequality below?
X^2>=81
A. x ≤ - 9 or x ≥ 9
Step-by-step explanation:x² ≥ 81
| x | ≥ 9
x ≥ 0 => x ≥ 9 => x ∈ [ 9 ; + oo)
x < 0 => x ≤ - 9 => x ∈ ( -oo ; - 9 ]
x ∈ ( -oo ; - 9 ] ∪ [ 9 ; + oo)

Answer:
[tex]\lim_{x\to3^-}\sin{\frac{\pi}{\floor[x]}=1[/tex]
[tex]\lim_{x\to3^+}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]
[tex]\lim_{x\to3}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]
Step-by-step explanation:
So we want to left and right hand limits of the function:
[tex]f(x)=\sin{\frac{\pi}{\floor[x]}[/tex]
as x approaches 3.
Note that the [x] means the floor function a.k.a the greatest integer function. In other words, the value of the function will be the greatest integer less than or equal to x.
1) Left
So we have the limit:
[tex]\lim_{x\to3^-}\sin{\frac{\pi}{\floor[x]}[/tex]
Note that since we're coming from the left, the values are 2.9, 2.99, and 2.999...
As I mentioned previously, the floor function outputs the greatest integer less than or equal to x.
With 2.9, 2.99, and 2.999, the greatest integer less than or equal to x is 2.
Therefore:
[tex]=\sin{\frac{\pi}{2}[/tex]
Simplify:
[tex]=1[/tex]
So:
[tex]\lim_{x\to3^-}\sin{\frac{\pi}{\floor[x]}=1[/tex]
2) Right:
[tex]\lim_{x\to3^+}\sin{\frac{\pi}{\floor[x]}[/tex]
Since we're coming from the right this time, the values are going to be 3.01, 3.001, 3.001.
And, the greatest integer less than or equal to 3.01, 3.001, and 3.001... is 3.
Therefore:
[tex]=\sin{\frac{\pi}{3}[/tex]
Simplify:
[tex]=\frac{\sqrt3}{2}[/tex]
So:
[tex]\lim_{x\to3^+}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]
At 3:
So we have:
[tex]\lim_{x\to3}\sin{\frac{\pi}{\floor[x]}[/tex]
The greatest integer of 3 is just 3. So:
[tex]=\sin{\frac{\pi}{3}\\[/tex]
Simplify:
[tex]=\frac{\sqrt3}{2}[/tex]
So:
[tex]\lim_{x\to3}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]

Spackle paint supply had a beginning inventory of 10 cans of paint at 25 per can. They purchased 20 at 30 per can. They had an ending inventory valued 500. How much paint in dollars was used for the month
Answer:
The total number of paints used for the month = $350
Step-by-step explanation:
Given that:
Spackle paint had a beginning inventory of 10 can of paint at $25 per can =
10× $25 = $250
They purchased 20 at $30 per can.
The amount of the 20 purchased can = 20 × $30 = $600
The total inventory for this supply = $600 + $250
= $850
They had an ending inventory valued 500.
∴
The total number of paints used for the month = total inventory - ending inventory
The total number of paints used for the month = $850 - $500
The total number of paints used for the month = $350

Answer:
[tex] \boxed{ \huge{ \bold{ \boxed{ \sf{3 \: , \: 6 \: , \: 12}}}}}[/tex]
Step-by-step explanation:
Given,
E = { 1 , 2 , 3 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 }
Here, E is the universal set.
A = { x : x is a multiple of 3 }
Here, we have to list the multiples of 3 less than 16
A = { 3 , 6 , 9 , 12 , 15 }
B = { x : x is a factor of 24 }
Here, we have to list the factors of 24 less than 16 }
Factor of 24 means the numbers that can divide 24 easily.
Factor of 24 includes :
B = { 1 , 2 , 3 , 4 , 6 , 8 , 12 }
C = { x : x is an odd number }
Here, we have to list the odd numbers which are less than 16
C = { 1 , 3 , 5 , 7 , 9 , 11 , 13 , 15 }
Finding A ∩ B
Here, We have to find the common elements that are present in both A and B
{ 3 , 6 , 9 , 12 , 15 } ∩ { 1 , 2 , 3 , 4 , 6 , 8 , 12 }
= { 3 , 6 , 12 }

A new car costs $8000 at full price. With a sales tax of 5.75%, how much will the car cost in total?
Answer:
$8460
Step-by-step explanation:
So for this problem we will use the base price of $8000 and add the additional cost of the 5.75% to find the total cost for the car.
So, to find the 5.75%, we simply multiply 8000 by .0575 to get 460.
So 8000 + 460 = 8460.
Thus, the total price of the car would be $8460.
Cheers.
Answer: $8,460
Step-by-step explanation: If you multiply the cost of the car by the sales tax you get your answer. Hope this helps!
The sum of only negative numbers.
Is it positive or negative
Answer: negative
Step-by-step explanation: Whenever you are adding negative
numbers together, you will always get a negative number.
For example, (-1) + (-1) will give you -2.
In the same way, (-5) + (-4) gives you -9.
Answer: negaitive
When you add a negative plus a negative you always get another negative

Answer:
[tex]$-\frac{1}{4} (-2x-9+\sqrt{65})(2x+9+\sqrt{65})$[/tex]
Step-by-step explanation:
We have a second-degree polynomial:
I will find the roots (y = 0) completing the square:
[tex]$x^2+9x+\frac{81}{4}-\frac{81}{4}+4=0$[/tex]
[tex]$\left(x+\frac{9}{2} \right)^2 -\frac{81}{4} +4 =0$[/tex]
[tex]$\left(x+\frac{9}{2} \right)^2 -\frac{81}{4} +\frac{16}{4} =0$[/tex]
[tex]$\left(x+\frac{9}{2} \right)^2 -\frac{65}{4} =0$[/tex]
[tex]$\left(x+\frac{9}{2} \right)^2 =\frac{65}{4} $[/tex]
[tex]$\left(x+\frac{9}{2} \right)^2 =\pm \sqrt{\frac{65}{4} } $[/tex]
[tex]$x =-\frac{9}{2} \pm \frac{\sqrt{65} }{2} $[/tex]
