Answer:
64
Step-by-step explanation:
the expression is
x² - 16x + _
the constant term is the square of the number residing with x divided by 2
the number number x = 16
therefore the constant term is (16/ 2)²
= 8²
= 64
the formula being used here is
(x + a)² = x² + 2ax + a²
Answer:
The asnwer is 6.37 y
Step-by-step explanation:
You have to add them sum means addition
I hope this helps
The slope of points (-2,6) and (3,10) is m= 0.8
X intercept=(1,0)
Y intercept=(0,-2)
You get x by substituting 0 for y and you get y by substituting 0 for x therefore to find y coordinates,
2(0)-2=y
0-2=y
-2=y so (0,-2)
And to find x coordinates,
2x-2=0
2x=2
2x/2=2/2
X=1 so (1, 0)
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
