Answer:

y = 5x - 8

Step-by-step explanation:

The linear equation in slope intercept form :

y = mx + c

m = slope ; c = intercept

m = Rise / Run = (y2 - y1) / (x2 - x 1)

Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20

Run = (x2 - x1) = (4 - 0) = 4

Slope, m = Rise / Run = 20 /4 = 5

Hence,

y = 5x + c

For the points ; y = 12 ; x = 4 ; we could obtain c

12 = 5(4) + c

12 = 20 + c

12 - 20 = c

-8 = c

The equation becomes :

y = 5x - 8

1. y + 2.4 = 7.4
2. w − 3 = 11
3. 5 + y = 7
4. b + ½ = ⅔

1) y =
2) w =
3) y =

Bo invests money in an account paying a simple interest of 8% per year. If no money will be added or removed from the investment, what should he multiply his current balance by to find his total balance in a year in one step?

Answers

Answer:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

then, solving our equation

I = Prt (Where p=principle,r=rate,t=time)

I = p*0.08*1=0.08p

Step-by-step explanation:

Bo should multiply his current amount by 1.08 to get the complete balance in one step.

What is the simple interest?

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

We have been given that Bo invests money in an account paying a simple interest of 8% per year.

To find the total balance in a year, you can use the formula:

balance after 1 year = balance × (1 + (interest rate/100))

In this case, the interest rate is 8%, so you can use the formula like this:

balance after 1 year = balance × (1 + (8/100))

This simplifies to:

balance after 1 year = balance × 1.08

Therefore, to find the total balance in one step, Bo should multiply his current balance by 1.08.

16 quarts of soil are used to completely fill 5 flower pots. If each pot holds the same amount of soil, how many quarts will each pot hold?

Express your answer as a mixed number.

Answers

Answer:

The amount that each flower pot will hold is 3 1/5 quarts of soil.

Step-by-step explanation:

Since there's 16 quarts of soil being used to fill 5 flower pots, we just need to divide 16 by 5. 16 ÷ 5 = 3.2. This is a decimal, so we need to convert it into a mixed number. 3.2 is 3 2/10, which can be simplified into 3 1/5. Hope this helped!! :]

Always consider a percent as a fraction but it has to be out of 100.
