1. suppose you bought a new car in december 2010 for $15,000. a. according to the rule of thumb, what would the car be worth at each of these times? i. december 2011 ii. december 2015 iii. december 2020 b. develop a general formula for the value of the car t years after it's purchase.

f(x) = y

f(-3) = -5

step-by-step explanation:

the answer is (-4,-4)

hope this ! : d

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
