Answer:

Step-by-step explanation:
When solving for 1 variable, set the other to 0 and solve.

Answer:
c = 64
Step-by-step explanation:
Given
x² - 16x + c
To complete the square
add ( half the coefficient of the x- term )² to x² - 16x
x² + 2(- 8)x + 64
= (x - 8)²
Thus
x² - 16x + 64 = (x - 8)² ← a perfect square
with c = 64
No, Lily is not correct. This is because 16+3 does not equal 18. So to find N, you take 18 and subtract 16.
18-16=n
18-16=2
so n=2
16+2=18.
Answer:
-4
Step-by-step explanation:
The equation is in slope-intercept format, y=mx+b. The coefficient in front of the x is the slope as represented by the letter m.
