This morning, Raina's car had 18.18 gallons of fuel. Now, 5.7 gallons are left. How much fuel did Raina use?

12.48 gallons

Step-by-step explanation:

Subtract the starting amount from the ending amount

18.18 - 5.7

and get 12.48

she used 12.48

Step-by-step explanation:

if you subtract 5.7 from 18.18 you would get your answer.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
