Answer:
average speed = 8y/s
Step-by-step explanation:
- What is the player's average speed over this distance ?
Formula
s = d/t
d = 40 yards
t = 5 seconds
s = 40y/5s
= 8y/s
To move a graph up, you need to add the units tot he end of the equation.
The graph of f(x) is f(x) = 15x+60
So add 12 to the equation to get g(x) = 15x +72
The answer would be A.
4 thousands = 4,000
21 tens = 21*10 = 210
210 + 4,000 = 4,210
Answer: 4,210
Answer:

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (3, 1), hence
y = a(x - 3)² + 1
To find a substitute (- 2, - 4) into the equation
- 4 = a(- 2 - 3)² + 1
- 4 = 25a + 1 ( subtract 1 from both sides )
25a = - 5 ( divide both sides by 25 )
a = -
= - 
y = -
(x - 3)² + 1 ← in vertex form
