A rental truck cost $48 plus $0.40 per mile.

1 answer:

Natalija [7]4 years ago

3 0

(a) If we let x be the number of miles and y be the total cost, the equation for relating the number of miles and the total cost would be,
y = 0.4x + 48

(b) If the rental cost is 60,
60 = 0.4x + 48
The value of x from the equation is 30.

(c) You may prepare the table of values by allowing x be any number and then solve for y until we arrive with an answer for y being equal to 60.

An aircraft has a maximum of 30 first class seats and 220 economy seats.

Sidana [21]

Answer:

$x\leq 30$

$y\leq 220$

$240x+120y$

Step-by-step explanation:

Let

x ----> the number of first class seats

y ----> the number of economy class seats

we know that

An aircraft has a maximum of 30 first class seats

so

$x\leq 30$

An aircraft has a maximum of 220 economy seats

$y\leq 220$

A flight will be cancelled if the money taken for the seats is less than $28,800.

so

$240x+120y$

therefore

Three inequalities that represent the situation are

$x\leq 30$

$y\leq 220$

$240x+120y$

IV. Intercepts. Give the intercepts of the following linear equations. 1) 5x + 3y = 8 2) 10x + 6y - 12 = 4 3) 2x – 3y = 5 4) 3x

rosijanka [135]

Answer:

1) $\frac{8}{3}$

2) $\frac{8}{3}$

3) $\frac{-5}{3}$

4)2

Step-by-step explanation:

1) 5x + 3y = 8

3y=8-5x

$y=\frac{-5}{8} x+\frac{8}{3}$

hence intercept is $\frac{8}{3}$

2) 10x + 6y - 12 = 4

10x + 6y = 16

6y=16-10x

$y=\frac{-10}{6} x+\frac{16}{6}$

hence intercept is $\frac{8}{3}$

3) 2x – 3y = 5

3y=2x-5

$y=\frac{2}{3} x+\frac{-5}{3}$

hence intercept is $\frac{-5}{3}$

4) 3x + 2y = 1

2y=-3x+4

$y=\frac{-3}{2} x+\frac{4}{2}$

hence intercept is 2
