Daniela rented a car. she paid a flat rate for the day, plus a cost per mile charge. the expression 0.15x+220.15x+22 represents the amount daniela paid. what do the different parts of the expression model? drag the parts of the expression into the boxes to match each description. daily flat rate cost per mile number of miles driven 22 0.15 x 0.15x

Let

x--------> the number of miles driven

y--------> the amount in dollars that Daniela paid

we know that

where

-------> represent the daily flat rate (the y-coordinate of the y-intercept of the linear equation)

-------> represent the cost per mile (the slope of the linear equation)  

---------> number of miles driven

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
