Question

Evaluate-4x-y+4when x= - 1/4 and y = 3

Answer 1

If you plug in the x and y values into the equation you should be left with
-4 (-1/4) - (3) + 4
after simplifying you are left with 1 + 1

therefore your answer is 2

Answer 2

2

Step-by-step explanation:

Given:

-4x - y + 4

when x = -1/4, y = 3

To get the solution, we replace x with -1/4 and y with 3 in the eexpression given.

-4(-1/4) - (3) + 4

Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.

= 1 - 3 + 4

= 2
