A bike shop rents each of its mountain bikes for a one time $4.00 insurance charge plus $2.50 per hour create an equation that r

egoroff_w [7]

Answer:

$y=2.50x+4.00$

Step-by-step explanation:

Let

x -----> the number of hours

y ----> the total cost to rent a bike in dollars

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope or the unit rate of the linear equation

b is the y-intercept or the initial value

In this problem we have

The unit rate or slope is equal to

$m=\$2.50\ per\ hour$

The y-intercept (value of y when the value of x is equal to zero) is equal to

$b=\$4.00$ ----> (fee charge)

substitute the values

$y=2.50x+4.00$

M is the midpoint of AN, A has coordinates (7, -4) and M has coordinates (3, 2) Find the coordinates of N.

Crank

Well if you use graph paper you can graph the points you already have and then you can find the slope of the line easiest that way, the next point would be. (-1,8)

William scored 24.5 points out of 30 on his math assignment. His teacher subtracted 5 points for being late. How many points is

Svetradugi [14.3K]

Answer:

William was 0.5 points away from a perfect score.

Step-by-step explanation:

If the teacher didn't subtract 5 points, he would have 24.5 + 5 = 29.5 points.

30 - 29.5 = 0.5

William was 0.5 points away from a perfect score.

What is the greatest common factor of 10, 20, and 50?

Viefleur [7K]

Answer:

Step-by-step explanation:

first you need to find the prime factors of the three numbers

ex:

prime factor of 18= $2*3*3$

prime of 24= $2*2*2*3$

there is one 2 and one 3 in common

greatest common multiple 2*3=6

so the greatest common multiple is ten because it is the only one that can divide between all three evenly.

$10=10/10=1\\20=20/10=2\\50=50/10=5$

so 10 is your answer
