Answer:
Step-by-step explanation:
150/6= 25
The rate is 25 miles per gallon of gas
$21 - $3 = $18
$18 - $4.75 = $13.25
$13.25 - $4.75 = $8.50
$8.50 - $4.75 = $3.75
Which means that she played 3 games, and has $3.75 left over.
But if you were to divide 4.75 from 21 it would equal 4 games and $2 left over.
21 - 4.75 = 16. 25
16.25 - 4.75 = 11.50
11.50 - 4.75 = 6.75
6.75 - 4.75 = 2
4 games and $2 dollars left over.
Answer - 3
Vertex form is
y=a(x-h)²+k
vertex is (h,k)
to solve
input the given vertex and then the given point, solve for a
vertex at (-2,2) and a point is (-4,-10)
y=a(x-(-2))²+2
y=a(x+2)²+2
put point (-4,-10)
-10=a(-4+2)²+2
-10=a(-2)²+2
-10=4a+2
-12=4a
-3=a
y=-3(x+2)²+2
Answer:
Step-by-step explanation:
hello
so to know the maximum to y we can check the maximum of
f(x)=
f is derivable and f'(x)=6-2x
f'(x)=0 <=> x = 3
so the maximum is reached for x = 3
f(3)=18-9=9
and then
to be rigorous, we can write the variation table of y to show that there is only one maximum
hope this helps
