The line represented by the equation y=-3/2x is translated up 3 units.

Answer:

(0, 3)

Step-by-step explanation:

In slope intercept form, the y-intercept is the "b" or, in an example:

y = mx + b

- m is the slope

- b is the y-intercept

In our first equation, the b is 0 (y=-3/2x, there is no +/- b, so it is 0). If we add positive 3 (up 3 units) then the y-intercept will be 3. This, in a point, is shown with (0, 3) because the y-intercept is where the line hits the y-axis when x is 0.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

The equations of two functions are y=-21x+9 and y=24x+8 which function is changing more quickly? Explain

antoniya [11.8K]

Given:

The equations are

$y=-21x+9$

$y=24x+8$

To find:

Which function is changing more quickly.

Solution:

The slope intercept form of a line is

$y=mx+b$

Where m is slope and b is y-intercept.

On comparing $y=-21x+9$ with the slope intercept form, we get

$m_1=-21$

$|m_1|=|-21|$

$|m_1|=21$

On comparing $y=24x+8$ with the slope intercept form, we get

$m_2=24$

$|m_2|=24$

Since, $|m_1|$ , it means the absolute rate of change of second function is greater than the first function.

Therefore, the second function is changing more quickly.

In 2 years, you want to have $5000 in your savings account. Find the amount you should deposit if the account pays 3% annual int

muminat

The amount you should deposit is $4709.18

Step-by-step explanation:

The formula for compound interest, including principal sum is

$A=P(1+\frac{r}{n})^{nt}$ , where:

A is the future value of the investment/loan, including interest
P is the principal investment amount
r is the annual interest rate in decimal
n is the number of times that interest is compounded per unit t
t is the time the money is invested or borrowed for

∵ You want to have $5000 in your savings account in 2 years

∴ A = 5000

∴ t = 2

∵ The account pays 3% annual interest, compounded monthly

∴ r = 3% = 3 ÷ 100 = 0.03

∴ n = 12 ⇒ compounded monthly

- Substitute these values in the formula above

∴ $5000=P(1+\frac{0.03}{12})^{(12)(2)}$

∴ $5000=P(1+0.0025)^{24}$

∴ $5000=P(1.0025)^{24}$

- Divide both sides by $(1.0025)^{24}$

∴ P = 4709.18

The amount you should deposit is $4709.18
