Question

Evaluate −4x−y+4 when x= −1 over 4 and y=3.

Answer 1

When x = -1/4 and y = 3, the expression −4x − y + 4 evaluates to 2 after substituting the values and performing the arithmetic operations.

Step-by-step explanation:

The student is asking to evaluate the expression −4x−y+4 for given values of x and y. To solve this, we simply substitute the provided values into the expression and calculate the result.

Substitute x = −1/4 and y = 3 into the expression:

−4(−1/4) − 3 + 4

= 1 − 3 + 4

= 2

Therefore, when x = −1/4 and y = 3, the expression −4x − y + 4 evaluates to 2.
