Answer:
4
Step-by-step explanation:
The vertex formula of a quadratic equation is:
●y= a(x-h)^2 +k
(h,k) are the coordinates of the vertex
Here: h = -5 and k= -2
y is 2 and x is -4
● 2 = a (-4-(-5))^2 + (-2)
● 2 = a (-4+5)^2 -2
● 2 = a *1^2 -2
● 2 = a -2
● 4 = a
Hello!
We have to find how fast the car goes a minute
To find this we can do 57/60 since the car goes 57 miles an hour and there are 60 minutes in an hour
This gives us 0.95 miles a minutes
The point (-3,11) is a solution to : y > = x - 2, 2x + y < = 5
You just put the numbers in the formula 3x30 = 90 km
