Answer:
Ann us correct. It's a quadratic function.
Step-by-step explanation:
Given equation is,
y = 3x(x - 7)
By converting this equation into the standard quadratic equation,
y = 3x² - 21x
Highest exponent of the polynomial equation is 2 (Exponent of highest degree variable x²). This decides that the given function is a quadratic function.
Therefore, Ann is correct. It's a quadratic function.

Answer: unit rate = 1 / 5 = 0.2 inches per day
Step-by-step explanation:
The unit rate is the ratio that describes how one quantity changes as the other changes.You can find a unit rate from a graph the same way you find the slope.
1. Choose two points on the graph to find the slope
- (0,0) and (5,1)
x₁ y₁ x₂ y₂
2. Slope = y₂ - y₁ / x₂ - x₁ (This is essentially the change in y-coordinates divided by the change in x-coordinates.
unit rate = y₂ - y₁ / x₂ - x₁
unit rate = 1 - 0 / 5 - 0
unit rate = 1 / 5 = 0.2 inches per day
Answer:
-5x - 24
Step-by-step explanation:
3(2x − 8) – 11x =
Distribute the 3.
= 6x - 24 - 11x
Combine like terms.
= -5x - 24
