For this, all you have to do is create equations where all you have to do is change the x value. The equation for gym A would be 35 + 42x, where x is the number of months he has the membership, and the first number is the initial fee. The equation for gym B would be 65 + 36x, following the same rules. Now all you have to do is set both of these equations equal to each other:
65+36x=35+42x
Solving this equation results in x=5, which means that he has to have the memberships for 5 months for them to be equal. Now just plug that in to one side of the equation to get the amount he has to spend:
65+36(5) = $245
For this case we have the following ordered pairs:
(6, 9)
(4, 6)
The scale factor can be found in two different ways:
Therefore, the scale factor is given by:
Answer:
The scale factor of the dilation is 1.5
Yes because if you take 4:3 it equals out to be 2:1.5
Battery is down currently = 2/5
Battery drains at the rate of 1/9 every hour.
Remaining battery life of Vera = 1 -2/5 = 3/5
Let y we the number of hours battery will last.
So, 1/9 y = 3/5
y = 27/5
y = 5 + 2/5 hours
y = 5 hrs and 24 mins
So battery will last another 5 hrs and 24 mins.
hope this helps:)
