What is the linear function equation represented by the graph?

SVETLANKA909090 [29]

Answer:

$y=\frac{1}{3}x -4$

Step-by-step explanation:

To write a linear function, use y=mx+b where m is the slope and b is the y-intercept. The y-intercept is where the line on the graph crosses the y-axis. On the graph is crosses at (0,-4). So b=-4. To find the slope, subtract the difference between two points on the line which cross through a grid line intersection. (0,-4) is one point. (3,-3) is another.

$\frac{-3--4}{3-0}=\frac{-3+4}{3} =\frac{1}{3}$

Input 1/3 and b=-4 into y=mx+b.

$y=\frac{1}{3}x -4$

Priscilla invests $10,000 in an account that compounds interest continuously and earns 11%. How long will it take for her money

Shkiper50 [21]

Answer:

Step-by-step explanation:

When the interest compounds continuously, our formula is

$A(t)=Pe^{rt}$

If we start with 10000 and are looking for how long, t, it takes to double, we are looking for how long it will take for our account to have 2 times 10000. That's 20000. Therefore, our equation is

$20000=10000e^{.11t}$

Divide both sides by 10000 to get

$2=e^{.11t}$

Take the natural log of both sides to "undo" that e:

$ln(2)=ln(e^{.11t})$

Again, since ln and e undo each other what we have now is

ln(2) = .11t and

$\frac{ln(2)}{.11}=t$ so

t = 6.3 years

Margaret [11]

Answer:

Make payments on or before the due date; Pay off the full amount with the first monthly statement; Have a plan of how you will repay the money.

Explanation:

Good credit practices will help build your credit.

You must pay at least the minimum amount due each month in order to avoid late fees and derogatory marks on your credit report. This means the first option is not correct.

Making payments on or before the due date will keep your account in good standing. This option is correct.

Paying off the full amount with the first monthly statement, while it does not help y

our credit score much, will keep your account in good standing. This option is correct.

Having a plan of how you will repay the money you borrow is essential before you start borrowing. This option is correct.

Choosing the credit card with the highest interest rate will cause you to pay more over the lifetime of the balance. This is not something you want; this option is not correct.

valentina_108 [34]

Answer:

Girl's basketball team has more seniors

Step-by-step explanation:

A varsity boy's basketball team has ratio of seniors to juniors that is 7:4.

Let there are 7x seniors and 4x juniors in boy's basketball team.

ATQ,

7x+4x = 12

11x = 12

x = 12/11

Seniors = $7\times \dfrac{12}{11}=7.63$

The varsity girl's basketball team has a ratio of seniors to juniors that is 3 to 2.

Let there are 7x seniors and 4x juniors in girl's basketball team.

3x+2x = 12

5x = 12

x = 12/5

Seniors = $7\times \dfrac{12}{5}=16.8$

As we can see that girl's basketball team has more seniors as compared to the boy's team.
