Answer:

- 29

Explanation:

= 8x + 4y - 25

Sub in x = - 2 , y = 3

= 8 ( - 2 ) + 4 ( 3 ) - 25

Answer:

-29

Explanation:

So we have the expression:


8x+4y-25

And we want to evaluate it for x=-2 and y=3. So, substitute:


=8(-2)+4(3)-25

Multiply:


=-16+12-25

Add:


=-4-25

Subtract:


=-29

And we're done!
