The final bill is $544
The parts is a one time bill of $265
The labor is $48 per hour, and lets call the hours 'h'
So we can make the equation as:
544 = 265 + 48h
Subtract 265 n both sides
279 = 48h
Divide by 48 on both sides
h = <span>5.8125
So the number of hours of labor spent repairing the car is </span><span>5.8125.</span>
Answer:
y = -9/4x
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= ( -9-9)/(4 - -4)
( -9-9)/(4+4)
-18/8
-9/4
Slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = -9/4 +b
Substitute a point into the equation
9 = -9/4(-4) +b
9 = 9+b
b=0
y = -9/4x
Answer:
35:14
Step-by-step explanation:
The ratio is 5:2.
The smaller number is 14, which replaces the 2. First, find the factor you used to get to 14. To do so, divide 14 by the smaller ratio number, 2:
14/2 = 7
Now, multiply 7 to the other side of the ratio:
5 x 7 = 35
If 5:2 ∴ 35:14
35:14 is your ratio.
