y = - 
(x - 5)² + 4
the equation of a quadratic in standard form is
y = a(x - h)² + k ( where (h , k ) are the coordinates of the vertex and a is a multiplier )
given vertex = ( 5, 4 ) then
y = a(x - 5)² + 4 ( to find a substitute (7 , 1 ) into the equation )
1= 4a + 4
4a = - 3 ⇒ a = -
y = - (x - 5)² + 4 ← ( in vertex form )

Answer:
10 miles
Step-by-step explanation:
Let m represent the number of miles Kayla runs. We want to find m such that ...
0.50m = 5.00
Divide by the coefficient of m:
m = 5.00/0.50 = 10
Kayla has to run 10 miles to get the same donation from both parents.
Answer:
134
Step-by-step explanation:
1. seperate the rectangle bottom and the triangle top
2. I did the triangle first: 4×12=48÷2=24
3. the rectangle: 11×10=110
4. add the final numbers together: 110+24=134
Is there a graph or something?
