X + 4y = -8
5x - 4y = -16

for the 2 one x=  4 /5y + -16/5

for the first one x=−4y−8

Are they 2 sperate questions?

If yes here

1. x + 4y = -8

4y=−8

Step 1: Add -4y to both sides.

x+4y+−4y=−8+−4y

x=−4y−8

x=−4y−8

2. 5x - 4y = -16

5x−4y=−16

Step 1: Add 4y to both sides.

5x−4y+4y=−16+4y

5x=4y−16

Step 2: Divide both sides by 5.

5x =  4y- 16

 5            5

5 x/4  = 5y + -16

               5

x=  4 /5y + -16/5

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
