Answer:
When a line is parallel to another line, they have the same slope. So far the equation would be, y=4x+b. To find the value of b, substitute the given point into the equation.
8=4(-1)+b
8=-4+b
b=12
So, the equation of the line is y=4x+12.

So, first, what are the two sides?
let's call then x and y
we know that 2(x+y)=12.5 (that's the distance around)
so that means that x+y=6.25 (I just divided both by 2)
now, x=4y (from "4 times as long as it is wide")
so we can substitute:
x+4x=6.25
5x=6.25
x=1.25
so one side, is 1.25 and the other will be 1.25*4=5
and for the area we multiply the two:
1.25*5=6.25 square kilometers, and this is the answer!
Answer:
Radius is 8 cm, this means that the diameter is 16 cm. the circumference formula is 2(pie)R 2x3.14xRadius... Your answer is 50.265CM
Step-by-step explanation:
X=25 in this equation. But if u divide by 12 it’s -25
Do you have a picture to show, so that I can help?
