Answer:
A and B
Step-by-step explanation:
Quadratic Equations: f(x) = a(bx - h)² + k
Quadratic equations always have a degree of 2. That means that we will always have an x² term. Of the 4 choices, only A and B offer a term of x², making them a quadratic.
18 + 1/2 x (9 - 4) =
18 + 1/2 x 5
18 + 2.5
20.5
20.5 is your answer.
Answer:
177
Step-by-step explanation:
2/3 are women.
that means the remainder, 1/3, are men.
59 = 1/3 of all kindergarten teachers (3/3 = 1 representing the "whole").
so,
59×3 = 177
is the number of all kindergarten teachers employed by the school district.
Let x represent the number of song downloads and let y represent the total cost
y=0.95x+70
To convert hour into minute: (No. of hour × 60) minutes
So, 2/5 hours = (2/5 × 60) minutes = (120/5) minutes = 24 minutes
