Each day you run on a treadmill for “r” minutes and lift weights for 15 minutes. which expressions can you use to find how many minutes of exercise you do in 5 days?

a. 5(r+15)
b.5r+5•15
c.5r+15
d. r(5+15)

explain your reasoning:
a: they are both expressions with r as the variable

b: they are not equivalent expressions

c: they are equivalent expressions

d: both expressions contain the terms 5,r, and 15

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
