Answer:

A

Step-by-step explanation:

If you multiply the price for each mule x the amount of miles + the daily rental, you get the price. If you do this for each option and each car rental then you can see when the answers add up.

.75x56+20=62

.50x56+34=62

Answer:  A. 56 miles.

Step-by-step explanation:

Formula,

Total rent for car = Fixed rate + (Additional rate per mile) x (Number of mile)

Let x be the number of miles droven .

As per given ,

A car rental company charges $34 per day for a rented car and $0.50 for every mile driven.

i.e. Total rent for car = 34 +0.5x   ...(i)

A second rental company charges $20 per day and $0.75 for every mile driven.

i.e. Total rent for car = 20 +0.75x   ...(ii)

If both company charges the same , then from (i ) and (ii) , we have

20 +0.75x = 34 +0.5x\\\\\Rightarrow\ 0.25x=14\\\\\Rightarrow\ x=\dfrac{14}{0.25}=\dfrac{1400}{25}\\\\\Rightarrow\ x=56

Hence, the number of miles at which both companies charge the same amount for a one-day rental = 56 miles

Thus, the correct answer is A. 56 miles.

Answer:

S(1,2)

Step-by-step explanation:

The value that is being altered is the y value if you go from Q to T and then T to S. The x value = 1 and remains the same for point S.

To go from Q to T, you go from 8 to 5 on the y value. Remember x remains the same. That's three units (8 - 5 = 3)

To go from T to S must be 3 units as well, since the small diagonal is bisected. 5 - 3 = 2 is the answer.

So point S is noted as S(1,2)
