Answer:

6. 4x

7. 3y

8. y - 4.5

9. 7/2x + 2

Step-by-step explanation:

6.

x + x + x + x

Combine like terms by adding

4x

7.

4y - y

Combine like terms by subtracting

3y

8.

7y - 4.5 - 6y

Combine like terms by subtracting

1y - 4.5

y - 4.5

4.5 does not have the same variable as the other term in the expression, therefore we cannot do anything further to it

9.

4x + 2 - 1/2x

Combine like terms by subtracting

One like term is a fraction so we must convert the whole number into a fraction with the same denominator

4/1x = ?/2

Cross multiply

4 × 2 = 1x × ?

8 = 2x

This is our new fraction: 8/2x because 4x = 8/2x

Substitute this new fraction into the expression

8/2x + 2 - 1/2x

Combine like terms by subtracting the numerators

7/2x + 2

Neither are like terms so they cannot be added together

The heights of two elevators can be modelled by linear functions. At time t = 0, Elevator A is 16 feet above ground floor. It descends at a rate of 4 feet per minute. The height of Elevator B is shown in the graph. Select all true statements.

Elevator B graph of a diagonal line on a coordinate plane going down and to the right with Time in minutes on the x axis and height in feet on the y axis. The line begins at the point zero comma 16 and passes through the point 2 comma 10.

Select all True Statements.

The initial height of Elevator A is less than the initial height of Elevator B.

Elevator A descends at a faster rate than Elevator B.

Elevator A will reach the ground first.

Elevator B will reach the ground first.

The initial height of Elevator B is less than the initial height of Elevator A.
