Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition

x = 2 when y = 2

k = yx = 2 × 2 = 4, hence

y = \frac{4}{x} ← equation of variation

Jasmine wants to use her savings of $1,128 to buy video games and music cds. The total price of the music cd she bought was $72.
Firlakuza [10]
24 video games.

First you subtract $72 from $1,128 then you divide $43 from $1,056 and you get 24.5581395
So the most video games jasmine can buy is 24.

A truck rental company rents a moving truck One Day by charging $39 + 0.09 per mile write a linear equation that relates the cos
Ivanshal [37]

Answer:

(a)\ c(x) = 39 + 0.09 x

(b)\ \$53.4

Step-by-step explanation:

Given

Base\ Charge = \$39

Rate = 0.09 per mile

Solving (a): Linear Equation

The total charges (c(x)) is: the base charge + the rate * number of miles (x).

So, we have:

c(x)= 39 + 0.09 * x

c(x) = 39 + 0.09 x

Solving (b): Cost of rent, if miles = 160

This implies that x = 160

So, we have:

c(x) = 39 + 0.09 x

c(160) = 39 + 0.09 *160

c(160) = 39 + 14.4

c(160) = 53.4
