The scale on a map shows that 5 centimeters=2 kilometers.
part a
what number of cm on the map represents an actual distance of 5 km?
part b
what is the actual number of km that is represented by 2 cm on the map?

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

step-by-step explanation:

classify each pair of angles as alternate interior, same-side interior, or corresponding angles.

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
