Answer:
x< -8.125
Step-by-step explanation:
7(x+4) < 2(x-5) -3(x+9)
distribute 7, 2, -3 to the parentheses to the right
7x+28<2x-10-3x-27
add like terms
7x+28<x-37
add x to 7x and subtract -28 to -37
8x<-65
divide both sides by 8
x<-8.125 or (-65/8)
<span>A scale factor is a number which scales, or multiplies, some quantity. The ratio of
any two corresponding lengths in two similar geometric figures is also
called a scale factor.
Given a function
which is formed from the parent function

The function
</span><span>

was obtained from the parent function by multiplying the parent function by 3.
Therefore, the scale factor of the function </span><span>

is 3.</span>
Answer:
The answer is C.
Step-by-step explanation:
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
The answer is 8n^2
2x2 is 4 x 2 is 8 two n variables so multiple it by 2 and you get your answer
