The running track shown in the diagram has 2 straight sides. Both ends of the track are semi-circles, or half circles. What is the distance of one lap around the track?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the answer is a.

135 and 80

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
