The Vertex of the parabola is V=(-5,-2)=(h,k)→h=-5, k=-2
This is a vertical parabola, then its equation has the form:
y=a(x-h)^2+k
Relacing h=-5 and k=-2
y=a(x-(-5))^2+(-2)
y=a(x+5)^2-2
When the x-value is -4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation:
a=?
x=-4, y=2→2=a(-4+5)^2-2
2=a(1)^2-2
2=a(1)-2
2=a-2
2+2=a-2+2
4=a
a=4
Answer: The coefficient of the squared expression in the parabola's equation is 4
Answer: Option B. 4
Answer:
It would make it easier
Step-by-step explanation:
Like if u would want to find the unit rate u could make an equation like y= 2x which would help u in a graph.
Answer:
-1
Step-by-step explanation:
all you gotta do is do rise over run which is just y over x so you get -1/+1 which equals -1
hope this helps!
have a good one!!
God bless you!

Y=15-0.04x since the value at x=0 is still 15, then it starts from 15, and it goes down 0.4 after 10=x so 0.4/10
