Y-585 = -7.5(x-15)
y = -7.5x - 7.5(-15) + 585
y = -7.5x + 697.50
C = -7.5(52) + 697.50 = $307.50
Answer:
<h3>x = 5</h3>
Step-by-step explanation:
The sum of two complementary angle is 90 degrees. Given the following complementary angles;
<1 = 6x + 5
<2 = 8x + 15
<1 + <2 = 90 (complementary angles)
6x + 5 + 8x + 15 = 90
14x + 20 = 90
14x = 90-20
14x = 70
x = 70/14
x = 5
Hence the measure of x is 5
Select any two x and plug it into the equation to get the corresponding y:
I’ll do 1 and 2 for example.
x = 1
y = -2(1) + 4
y = -2 + 4
y = 2
So we have the point (1, 2)
x = 2
y = -2(2) + 4
y = -4 + 4
y = 0
We have the point (0, 2)
Plot (1, 2) and (0, 2) and draw the line that goes through both.
