Answer:

15 customers were outside

Step-by-step explanation:

Represent customers inside with x and customers outside with y.

So, we have:

x = \frac{1}{3}y - 2 --- First Statement

x = 3 --- Second Statement

Required

Find y

Substitute 3 for x in x = \frac{1}{3}y - 2

3 = \frac{1}{3}y - 2

Add 2 to both sides

2 + 3 = \frac{1}{3}y - 2 + 2

2 + 3 = \frac{1}{3}y

5= \frac{1}{3}y

Multiply both sides by 3

3 * 5= \frac{1}{3}y  *3

15 = y

y = 15

<em>Hence; 15 customers were outside</em>

Peter hired a cleaning company to clean his house. The cleaning company charges a fixed fee of $15 plus $17 per hour to clean a
almond37 [142]

Answer:

5 (for c only)

Step-by-step explanation:

for c:

1st cleaning company: y=17x+15

2nd cleaning company: y=20x

set up as a system of equations. for them to cancle out make the y of one equation negative. I'll be making the second one negative ( it doesn't matter though)

it will look like:

y=17x+15

-y=-20x

make the two equations on top of eachother and line the terms up. Then combine them. The variable "y" will cancle out and you'll be left with

0=-3x+15

then you will add 3x to both sides to get 3x=15 then divide both sides by 3 to get x=5

if you plug in 5 for x into both of the original equations you will see that they will both make $100 in five hours. So you answer is 5

What is the value of $750 invested into an account with an annual rate of 3.25% compounded continuously for 4 years and 3 months
Goshia [24]

Answer:

$861.09

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

A = Pe^{rt}

<em>A = total </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal) </em>

<em>t = time (years) </em>

<em />

First, change 3.25% into its decimal form:

3.25% -> \frac{3.25}{100} -> 0.0325

Next for <em>t, </em>we can use 4.25 since 4 years and 3 months is 4.25 in its decimal form. Now lets plug in the values:

A=750e^{(0.0325)4.25}

A=861.09

Your answer is $861.09

The general formula for the equation of the straight line is:
y−b=m(x−a) where
m is the slope 
a is the x coordinate of the given point
b is the y coordinate of the given point

The slope is given as 2
x coordinate in the given point is 5
y coordinate of the given point is 9

Substitute with these values in the mentioned equation as follows:
y−9=2(x-5)
