5 0

Answer:

Step-by-step explanation:

Slope m is defined as m=(y2-y1)/(x2-x1) in this case

m=(218-155)/(22-15)=63/7=9

y=mx+b

y=9x+b, using point (15,155) we can solve for the y intercept b

155=9(15)+b

155=135+b, b=20 so the line is

y=9x+20

In thirty days there will be

y=9(30)+20=290 coins

John made a rectangle pen for his dog using 28 feet of fencing. If the width of the pen is 2 feet more than one-half the length,
kati45 [8]
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.

P = 28 ft.
Length = x
Width = (1/2)x + 2

So now we can plug in the little equations of length and width into a perimeter formula:
 2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8

To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6

So, the length is 8 feet and the width is 6 feet.
