Answer:
To form the table,
we substitute some value of x to find its value of y
When x = -2,
⇒ y = 1/2(-2) - 3 = -4
When x = - 1
⇒ y = 1/2(-1) - 3 = -3.5
When x = 0.
⇒ y = 1/2(0) - 3 = -3
When x = 1
⇒ y = 1/2(1) - 3 = -2.5
When x = 2
⇒ y = 1/2(2) - 3 = -2

Answer is NO, it does not double.
Step by step.
Equation for surface area (SA) = 2lw+2lh+2wh
If we double the length and width, making them each 2l and 2w, we then have:
2(2l x 2w) + 2(2l x h) + 2(2w x h)
= 2(4lw) + 4lh + 4wh
SA = 8lw + 4lh + 4wh
If the surface area had been doubled, we should get the equation (4lw + 4lh + 4wh) for a doubled surface area.
So no, it is not doubled.
Given:
Consider the sides of the triangle are 4x+10, 2x-5 and 18 (in feet).
Perimeter of this triangle is to be no more than 77 feet.
To find:
The inequality and solution of the inequality.
Solution:
Perimeter of a triangle is the sum of all side.
Perimeter of given triangle 
Perimeter of this triangle is to be no more than 77 feet. It means perimeter must be less than or equal to 77.
Divide both sides by 6.
Therefore, the required inequality is and the solution is .
For (polynomial)/(x-constant)
do
constant | coefients of polynomial
|___________________
if write 1 for every power, if a power is missing, write 0 tehre
this is kind of complicated
so what you do is start at the top, at the first number inside that wierd thing
bring it down below the line
multiply the left number
move it up and right 1 collumn
add that collumn, and write the sum below the line
repeat
so for yours
(x-4) so the constant outside is 4
so
4|1 13 -64 -20 16
|_______________
bring down the first row thing
4|1 13 -64 -20 16

1 17 4 -4
add
4|1 13 -64 -20 16
|___<u>4__68_16_-16</u>
1 17 4 -4 0
so the coefients 1,17,4,-4,0
and since we started with 4th degree (x^4) we minus 1 (to get x^3)
1x^3+17x^2+4x-4 and 0 remainder
2nd option is your answer
Add the prices together
Then divide by 3.
*6.25 + 3.25 = 9.50/3 = 2 of them pay 3.16 while the other pays 3.17.
