Answer:
y=1/5x+2
Step-by-step explanation:
In perpendicular lines the slopes are negative reciprocals so the slope of other line is 1/5x
And they intersect at (15,5) to find the y intercept(b)
y=1/5x+b
5=(1/5)(15)+b
5=3+b
b=2
Cross-multiply so that 8(3x + 1) = 14(2x)
Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x
Subtract 24x from both sides:
8 = 4x
Divide both sides by 4:
x = 2
Answer:
$26.91
Step-by-step explanation:
9.50 +13.93 =23.43
50.34 - 23.43 = 26.91
It's multiplying by 2 each time 10 x 2 = 20, 20 x 2 = 40, 40 x 2 = 80.
