Suppose that the function f(x)=7x+2 represents the number of cars that drive by in x minutes how many cars will drive by in 10 minutes

A. 27
B. 70
C. 72
D.90

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

step-by-step explanation:

4n=2m

ratio of m to n: 2/4 = 1/2

answer

a. 1/2
