Each week, Arnold earns $92 for every shift he works at the theater and $13 for every dog-walking job. He uses the expression 92x + 13y to keep track of his earnings. Part A: Identify the coefficients and variables in the expression. (3 points)

Part B: How many terms are in the expression, what are they, and how do you know? (4 points)

Part C: Which term in the expression shows the total earned from the dog walking jobs? (3 points)

Part A: Identify the coefficients and variables in the expression.

The variables in the expression is:

The number of shifts he works in the theater is represented by x

The number of dog walking jobs is represented by y

The coefficients =

Amount paid for each shifts = $92

Amount paid for each dog walking jobs = $13.

Part B: How many terms are in the expression, what are they, and how do you know?

There are two terms in the expression

They are: 92x and 13y

Part C: Which term in the expression shows the total earned from the dog walking jobs?

13y

Step-by-step explanation:

Each week, Arnold earns $92 for every shift he works at the theater and $13 for every dog-walking job. He uses the expression 92x + 13y to keep track of his earnings.

Part A: Identify the coefficients and variables in the expression. (3 points)

The variables in the expression is:

The number of shifts he works in the theater is represented by x

The number of dog walking jobs is represented by y

The coefficients =

Amount paid for each shifts = $92

Amount paid for each dog walking jobs = $13.

Part B: How many terms are in the expression, what are they, and how do you know?

The expression:

Total earnings = 92x + 13y

There are two terms in the expression

They are: 92x and 13y

Part C: Which term in the expression shows the total earned from the dog walking jobs?

Since the number of dog walking jobs is represented by y, the expression shows the total earned from the dog walking jobs is 13y

probability for j is 1/4

while

a is 1/6

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
