Find the x-intercepts of the parabola with vertex (-3,-18) and y-intercept at (0,0)

1 answer:

5 0

Y + 18 = a(x + 3)^2
0 + 18 = a(0 + 3)^2 
18 = 9a 
2 = a

y = 2(x + 3)^2 - 18 
0 = 2(x + 3)^2 - 18 
18 = 2(x + 3)^2 
9 = (x + 3)^2 
± 3 = x + 3 
-3 ± 3 = x 
x = 0 or -6

(0, 0) and (-6, 0)

What is the slope intercept form of the line that passes through the point (-2,-18) and has a slope of 1/4

mart [117]

Answer:

y=(1/4)x - 35/2

Step-by-step explanation:

y=mx+b

y=(x/4)+b plug in the slope (m)

-18=(-2/4)+b plug in x and y

b= -17 1/2= -35/2 solve for b

y=(1/4)x - 35/2 plug in m and b into the equation

Korolek [52]

Answer: :o I FINALLY MADE IT

(5, 2)

x = 5

y = 2

Step-by-step explanation:

First, I graphed both equations. They meet at the points (5,2) and (2,5). Because y < 5, the solution is (5, 2)

Hope it helps <3
