Joselyn is planning to install siding on her house. If "C" represents the total cost and "a" represents the area of her house, then how would you describe the action of the following equation?

• Joselyn adds the installation charges which is a fixed cost to the cost of siding and then multiplies it by 8, which is the siding cost per sq ft.

• Joselyn multiplies the area of her house with the variable cost of siding and then adds the installation charges which is fixed.

• The cost Joselyn has to pay depends on the area of her house and the installation cost.

• The installation cost is equal to the cost of siding added to the area of Joselyn's house times 8.

Aliyah and Bryan are trying to split a treasure of 12 gold coins and a bonus of 5 gold coins equally. How would you describe the actions they need to take to solve this problem for x?

• Add 5 to 12, and then divide by 2.

• Subtract a 5 from 12 and then divide by 2

• Add 5 to 12, and then multiply by 2.

• Subtract a 5 from 12 and then multiply by 2

Jada, Aliyah, Jazlynn, Anthony, and Viridiana are studying for their math test. They are trying to understand the range of all the logarithmic functions plotted on their study guide. Can you help them figure it out?

• The domain is always positive real numbers without a zero

• The domain is all real numbers

• The range is all real numbers

• The range is all real numbers without a zero

Andrea is trying to find the inverse of a function in her math homework. What should be her second step?

• Interchange x with y

• Replace f(x) with y

• Solve for y

• Solve for x

Andrea is planning to paint her trailer home. She needs to calculate the area of one of the long side of the trailer. How should she proceed?

• Multiply the length "x" with the width "13"

• Multiply the length "x" with the width "8"

• Multiply the length "13" with the width "8"

• Multiply the length "x" with the width "8" and then multiply it with 2
