Question

Most race cars are subject to various size and weight restrictions, depending on their classification. Champ cars must weigh a minimum of 1565 pounds without the driver. Formula One cars must weigh at least 1322.77 pounds with the driver. Select the two linear inequalities that can represent the possible weights of Champ cars and Formula One cars without drivers. Make sure you select two of the following. (Hint: Let x be the weight of the driver. ) Would it be choice D?

A. y ≥ 1565 - x
B. y ≥ (1322.77)x
C. y ≥ 1322.77 - x
D. y ≥ 1565

Answer 1

SOMEONE PLEASE HELP!

Answer 2

You have to pick out two inequalities. You chose D. That would be correct for the Champ cars that must weigh a minimum of 1565 pounds without the driver. However, which of the remaining inequalities do you think would indicate the weight of the Formula One car with the driver?

Answer 3

Is that other one choice A?

Answer 5

A deals with the number 1565, which is the minimum weight of the Champ cars w/o the driver. We are trying to find the expression that describes the Formula One car's weight with the driver. So it will be either B or C. Which make more sense to you.....to multiply the weight by the driver's weight (x) or to subtract the driver's weight?

Answer 6

Multiply? Is it B?

Answer 7

No, you want the weight of the Formula One car (y). You know that \[x + y \ge 1322.77\]

Answer 8

Rearrange and you get
\[y \ge1322.77-x\]
Answer C

Okay, thanks @pfenn1! :)
