Answer: -3
Step-by-step explanation:
-4
+ 
can be written as 
x
which is the same as 2
Also , can be written as 
x , which is the same as 5
Substituting into the main question , we have
-4 (2 ) + 5
= -8 + 5
= -3
Answer:
I'm pretty sure it's c but I'm not sure
Answer:
y = (x - 3)² + 6
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = x² - 6x + 15
add/subtract ( half the coefficient of the x- term )² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 15
y = (x - 3)² - 9 + 15
y = (x - 3)² + 6 ← in vertex form
