Answer:
B.-38
Step-by-step explanation:
2x - 18 = y ...(1)
x = -10 (Given)
Now,
Put the value of x in equation (1) we get,
2(-10) - 18 = y
-20 - 18 = y
-38 = y
<em><u>y = -38</u></em>
Thus, the value of y is -38

Answer:
B
Step-by-step explanation:
Given
x² - 18x + --- = 4 + ----
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 9)x + 81 = 4 + 81
(x - 9)² = 85 ( take the square root of both sides )
x - 9 = ± ( add 9 to both sides )
x = 9 ± ← exact solutions
