4x+y=-1
-5x-2y=-4

( -2, 7 )

Step-by-step explanation:

Solve 4x + y = -1 for y:

Add -4 to both sides:

4x + y + -4 = -1 + -4

y = -4x - 1

Now plug -4x -1 in the other equation with y:

-5x - 2 ( -4x -1 ) = -4

3x + 2 = -4

Add -2 to both sides:

3x + 2 - 2 = -4 + -2

3x = -6

Now divide both by 3:

3x/3 = -6/3

x = -2

Now plug in -2 in the first equation with x:

y = - 4 ( -2 ) - 1

y = 7

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
