Question

Let x = -2 and y = 3. Evaluate 8x + 4y - 25

Answer 1

Answer:

- 29

Step-by-step explanation:

= 8x + 4y - 25

Sub in x = - 2 , y = 3

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

= - 16 + 12 - 25

= - 29

Answer 2

Answer:

-29

Step-by-step 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!
