The function c(x) = 0.5x+70 represents the cost c (in dollars) of renting a truck from a moving company, where x is the number of miles you drive the truck Item 21 Question 1 The function c(x) = 0.5x+70 represents the cost c (in dollars) of renting a truck from a moving company, where x is the number of miles you drive the truck

Step-by-step explanation:

the given  function:

Where C = cost (in dollars) and x is the number of miles you drive the truck.

when we compare the given function by slope- the intercept form y=mx+b, what we get  is

Slope m = 0.5 whose fraction can be written as

And y-intercept b =70.

for us to be able to graph it, we need to plot y-intercept from 70  and then plot some more points by applying or increasing the points by

the shaded lines on the graph indicates the given function.

cost is at $70 for 0 number of miles. travelled.

Thus;

the Domain: x≥0 and Range :  ≥

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
