The product xy is constant, therefore, the relationship is an inverse variation.
First do 27 + 6 and then you were at 4 and get your answer + 27 + 6 is 33 then I have four and that is 37 and that's your answer
10.
a) x- is the time after which the total cost is the same.
24 + 99x - is the cost in the dealership
45 + 89x is the cost at the local mechanic
24 +99x = 45 + 89x
99x - 89x = 45 - 24
10x = 21
x= 2.1 (hours)
b) 24 +99x < 45 + 89x
x< 2.1
The repairs cost less in dealership when work takes less than 2.1, and the dealership is better, because the cost of parts is less in the dealership.
1/2•(bh) = A
bh/2= A
So, b= 2A/h
