Answer:

Y = x - 9

Step-by-step explanation:

A slope of 1 = x

So we have

Y = x

To find y intercept we do

7 - (-2) = 9

So we have a y-intercept of 9

Y = x - 9

Answer:

First answer is 14

Second answer is 25

Step-by-step explanation:

Median is the middle ( 1 2 3 4 5 the median would be 3)

You start at 2 and end at 27

List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)

In this case there are two 14 & 15

14+15=29 29÷2=14.5

Since there are no decimal answers you are left with 14

Range you take the two end numbers and subtract them (27 & 2)

27-2=25

Hopefully this helps!

Elena L [17]

Answer:

Part A: What would be worth the car's worth in 2 years?

V(2) = $ 391,114.50

Part B. In how many years will the car be worth $325,000?

t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days

Step-by-step explanation:

Part A: What would be worth the car's worth in 2 years?

If V(t) = 420,000(0.965) ^t, therefore:

V(2) = 420,000(0.965)²

V(2) = 420,000 * 0.931225

V(2) = $ 391,114.50

Part B. In how many years will the car be worth $325,000?

If V(t) = 420,000(0.965) ^t, therefore:

325,000 = 420,000(0.965) ^t

325,000/420,000 = (0.965) ^t

0.7738 = 0.965^t

t = log 0.965(0.7738)

t = log 0.7738/log 0.965

t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days

0.2 years = 0.2 * 12 = 2.4 months
