C) y= 7.5x-2
7.5 is a positive slope, and -2 will be your negative y intercept
y=mx+b
Remember m always means slope and b is always the y intercept!
Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
Answer:
its 6 because the lines show they are parellel so it has to be equal to 18 and 12 plus 6 is 18
