Plug the values (x,y) into the equation and check if they satisfy the equation.

(3,-2) \\
2 \times 3 + 7 \times (-2)=8 \\
6-14=8 \\
-8=8 \\
not \ true \\ \\
(2,-3) \\
2 \times 2+7 \times (-3)=8 \\
4-21=8 \\
-17=8 \\
not \ true

(-3,2) \\
2 \times (-3)+7 \times 2=8 \\
-6+14=8 \\
8=8 \\
true \\ \\
(0,4) \\
2 \times 0+7 \times 4=8 \\
0+28=8 \\
28=8 \\

What is the scale factor from L to S?
MariettaO [177]

Answer: While I don’t have the picture to actually know the answer I will explain how to get it.

Step-by-step explanation:

1. If the shapes are on a grid count the amount of grid squares that are located between each end point of the shape. If it’s not on a grid use a ruler to measure the side lengths. You will need to find out the side amounts for both shapes L and S.

2. From there if the L shape is SMALLER than the S shape, then take the S shape’s sides and divide it by the L shape’s sides, and whatever number you get from each of your division problems will be your scale factor. BUT If the L shape is BIGGER than the S shape then easiest way to find out your scale factor is to take the last scale factor you got and convert it into a fraction. For example, if you got 3 then it would be 1/3. Hope this helped!

If f(x)=x+8 and g(x)=-4-3 find (f+g)(x)
Lilit [14]

Answer:

(f+g)(x) = -3x+5

Step-by-step explanation:

f(x)=x+8 and g(x)=-4x-3

(f+g)(x) = f(x) + g(x)

             = x+8+-4x-3

             = -3x+5

V = 4/3(3)(10)³

V = 4(10)³

V = 4(1000)

V = 4000 ft³
