Slope intercept form is y = mx + b

So the slope intercept form for -5 and 2 is
y = 2x - 5

It would be this because the mx represents the slope and the b represents the y intercept so all you have to do is plug in the numbers.

a bus accelerates from 2 m/s to 10 m/s in 5 seconds. What was its average acceleration?

Please Help

Answers

Answer:

I believe the answer is 4. Please correct me if I’m wrong.

Step-by-step explanation:

Answer:  1.6 m/s^2

================================================

Work Shown:

A = old velocity = 2 m/s

B = new velocity = 10 m/s

C = change in time = 5 seconds

D = average acceleration

D = (change in velocity)/(change in time)

D = (B-A)/C

D = (10-2)/5

D = 8/5

D = 1.6 m/s^2

The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.

Michael bought a guitar that was on sale for 15% off the regular price of $200. The total cost included 8% sales tax. What was the total cost?

Answers

Answer:

$183.60

Step-by-step explanation:

Take the regular price and find the 15% discount:

200 x 0.15 = 30

Subtract the discounted amount from the original price:

200 - 30 = 170

Take the new price and find the sales tax:

170 x 0.08 = 13.60

Add the sales tax to the discounted price:

170 + 13.60 = 183.60
