Answer:
$65 is the original price
Step-by-step explanation:
65 x .8 = 52 which is 13 off
To calculate slope (which can be represented as the variable, m), we must use the equation for slope...
m =
Δy/Δx = (y-
)/(x-
)
We are given two points, each in format (x, y)
m = (13 - (-2)) / (-1 - 4) = 15 / -5 =
-3 (D)
They are to make variables.
You know that all of the triangles are congruent, so you only have to find the area of one and then multiply it by four. So you would multiply 5 by 7 and get 35. The divide that my two to get 17.5, which is the area of the triangles. Then you would multiply that by four and get 140, which is the area of the figure
