exponential fn:

2 180

3 540

4 1620

5 4860

each year is 3x of year be4

so year 0 (2012) is 180/3/3 = 20

y-intercept of linear fn (2012) is 150

The y-intercept of the exponential function is approximately 130 less than the y-intercept of the linear function

ans is B

The linear function in the graph shows the value, in dollars, of an investment in years after 2012; with the y-intercept between 140 and 160.


The exponential function in the table represents the balance of a savings account, in dollars, over time in years after 2012:

Years since 2012 Savings account balance ($)

2 180

3 540

4 1620

5 4860

Each year the balance increases by a factor of 3. So the y-intercept at Year 0 = Year 2/3^2 = 180/9

=20

That is approximately 130 less than the y-intercept of the linear function.


The answer is B.

If it takes 3 days for 10 workers to finish building one house, how many days will it take 15 workers to finish four houses?
Ksivusya [100]
-- It takes 10 workers 3 days to build 1 house.
so
-- It takes 10 workers 1 day to build  1/3  of a house.
so
-- It takes 1 worker 1 day to build  1/30  of a house.

You got 15 workers and you need 4 houses ?

Well, as we just calculated . . .

-- It takes 1 worker 1 day to build  1/30  of a house.
so
-- It takes 15 workers 1 day to build  15/30 = 1/2  of a house.
so
-- It takes 15 workers 2 days to build 1 whole house.
so
-- It takes 15 workers  8 days  to build 4 houses.

The line of the best fit is y = 4.71x—30.31 and at x = 9.5 inches the value of y is 14.5 oz.

<h3>What is the line of best fit?</h3>

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

First, we need to find the line of best fit:

Let's suppose the line of the best fit is:

y = mx + c

We can find the value of m:

\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}   and

\rm c = \dfrac{\sum y -m \sum x}{n}

After calculating, we will get:

m = 4.71

d = -30.31

y = 4.71x—30.31

Plug x = 9.5

y = 14.43 ≈ 14.5 oz

Thus, the line of the best fit is y = 4.71x—30.31 and at x = 9.5 inches the value of y is 14.5 oz.

15x+12(10-x)=141<br>make sure to use steps to solve!​
goldfiish [28.3K]

Answer: x=7

Step-by-step explanation: First you distribute the 12 to (10-x). That then gives you 15x+120-12x=141. Now you combine like terms. So you do 15x-12x=3x. Your new equation now is 3x+120=141. Subtract 120 from 141 and mark it out. That leaves you with 3x=21. Divide both sides by 3. Your final answer is x=7.
