The value of a building bought in 1990 appreciates, or increases, as time passes. 5 years after the building was bought, it was worth $138 comma 000; 17 years after it was bought, it was worth $162 comma 000.
a. If this relationship between number of years past 1990 and value of building is linear, write an equation describing this relationship. [Use ordered pairs of the form (years past 1990, value of building). Let x represent the number of years since 1990 and y represent the value of the building.]

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
