Answer:

about 900.

Step-by-step explanation:

The line down the middle seems to be a perpendicular bisector. that means that we've got to multiply 36 times two, which is 72 and multiply it times 25, and divide that result by two since the formula for a triangle is 1/2 times base times the height. I would not count on this however. To have a more exact result, I would use Pythagorean theorem to find the third side of the triangle on the right to then apply the area of a triangle formula, which would be:

0.5(72.20773398*25)=902.5966748

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 = 5.8125

So the number of hours of labor spent repairing the car is 5.8125.

Inverse of y= x-6/x+5

enot [183]

as you would already know, we start off to gettting any inverse of any expression by doing a quick switcheroo on the variables and then we solve for "y".

$\bf y = \cfrac{x-6}{x+5}\implies \stackrel{\textit{quick switcheroo}}{x = \cfrac{y-6}{y+5}}\implies x(y+5)=y-6\implies xy+5x=y-6 \\\\\\ xy+5x+6=y\implies 5x+6=y-xy\implies 5x+6=\stackrel{\textit{common factor}}{y(1-x)} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \cfrac{5x+6}{1-x}=\stackrel{f^{-1}(x)}{y}~\hfill$
