Answer:
Step-by-step explanation:
y=-1/13x since it is perpendicular flip it and make it negative
1. 1 5/8 / -1 3/5 = -25/24 = -1 1/24
2. -5 1/3 / 2 3/4 = 10/9 = -1 1/9
Answer:
55,000
Step-by-step explanation:
I already explained it on another problem but I'll show the equation again.
0.74x = 40,700
x = 55,000
Answer: y = -3/4x + 7
Step-by-step explanation:
first find slope:
y2-y1 / x2 - x1
1-4 / 8-4
-3/4
now just plug the slope (m) into the equation of a line using one of the points to find the y intercept
ill use (8,1)
1 = (-3/4)(8) + b
now solve :)
1 = -6 + b
7 = b
so now plug in the slope and the y intercept into the slope intercept form to find the equation of the line
y = -3/4x + 7
How much you need pay?
65x(1-25%)
=65x75%
=65x0.75
=48.75
Your answer should be $48.75.
