Question

determine the value of y, if x is -7.
y = x² + 10

Explanation:

Step1: Substitute x = -7 into the equation

We have the equation \( y = x^2 + 10 \), and we know \( x=-7 \). Substitute \( x = -7 \) into the equation: \( y=(-7)^2 + 10 \)

Step2: Calculate the square of -7

The square of -7 is \( (-7)^2=49 \), so the equation becomes \( y = 49+10 \)

Step3: Calculate the sum

Add 49 and 10: \( 49 + 10 = 59 \)

Answer:

\( y = 59 \)
