Janet deducted $5 on Monday and another $6 dollars on Tuesday from her savings account. Write an expression that represents the change in her account balance after the deductions. How much money did Janet deduct?

30

Step-by-step explanation:

5x6=30 so the change was that she deducted money in her account balance.

(3x-8) or (3x+8)

step-by-step explanation:

- "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."
