3. find an equation of a line through (0, −7) and parallel to the line y = 1 / 2 x + 5.
a. what is the slope of any line parallel to the given line? explain your answer.
b. write an equation of a line through the point and parallel to the line.
c. if a line is perpendicular to y = 1 / 2 x + 5, will it be perpendicular to x − 2y = 14? explain.

the slope of any line parallel to the given line is

perpendicular

Step-by-step explanation:

line

Slope of the given line is 1/2

Slope of parallel lines are same

the slope of any line parallel to the given line is

Equation of a line is y=mx+b

m=1/2  (x1,y1) is (0.-7)

Subtract x from both sides

Divide both sides by -2

slope of both lines are same so they are parallel.

So the line is perpendicular to

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
