The cost to fill a car's tank with gas and get a car wash is a linear function of the capacity of the tank. the costs of a fill-up and a car wash for three different customers are shown in the table. write an equation for the function in slope-intercept form. then, find the cost of a fill-up and a car wash for a customer with a truck whose tank size is 29 gallons.

answer: the correct answer is -32

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
