Answer:
Step-by-step explanation:
y + 5 = -8(x + 10)
y + 5 = -8x - 80
y = -8x - 85
Answer:
19 units
Step-by-step explanation:
A regular polygon has equal-length sides. This fact can be used to solve for the value of x, and for the side length. Knowing the side length, we can find the perimeter.
__
<h3>side length</h3>
5 -2x = 4x +9 . . . . . marked sides are the same length
-4 = 6x . . . . . add 2x -9
-2/3 = x . . . . . divide by 6
5 -2(-2/3) = 5 +4/3 = 6 1/3 . . . . length of one side
<h3>perimeter</h3>
The perimeter is the sum of the side lengths, or 3 times the length of one side.
P = 3s = 3(6 1/3)
P = 19 . . . . units
The perimeter of the polygon is 19 units.
Answer:
3650 yds
Step-by-step explanation:
Take the length that each person ran and multiply by the number of runners
5 * 730yds
3650 yds
Use the Pythagorean theorem:
X = sqrt(10^2 - 6^2)
X = sqrt(100-36)
X = sqrt(64)
X = 8
Answer:
Step-by-step explanation:
These are physical measurements, which must be zero or greater. These restrictions are the reason for your having a total of four inequalities.
