8 3/5 is between 8 and 9
so point D would be correct
If the $75 for the part is included in the $350 then it took 5.5 hours to install it
Here is my theory. I did not use the Pythagorean Theorem. I used basic cross multiplication.
z = 25
t = 24
We know that
The <span>abscissa is the x coordinate and the ordinate is the y coordinate
</span>so
for x=1.2
<span>8x–5y=14------> 8*1.2-5y=14-----> 5y=9.6-14-----> 5y=-4.4----> y=-0.88
the answer is
the ordinate is -0.88
