what is the equation of the line that is perpendicular to the given line and has an x-intercept of 6?​

Answers

Answer:

y = 4/3x - 6

Step-by-step explanation:

The slope of the 1st line is -3/4

So for the perpendicular line it has to be the exact opposite.

That looks like this ---> 4/3x

And the y-intercept is -6 because if you make a straight line where the x intercept is it matches.

The equation would look like this

y = 4/3x - 6

Jason bought a new truck at $25,000. The truck depreciates 15% of its value continuously each year. How much is it worth after 5 years? Round the answer to nearest dollar.

Answers

Answer:

A = $11093

Step-by-step explanation:

Given the following data;

Principal = $25,000

Rate = 15% = 15/100 = 0.15

Time, t = 5

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value. P is the principal or starting amount. r is annual interest rate. n is the number of times the interest is compounded in a year. t is the number of years for the compound interest.

Substituting into the equation, we have;

r = -0.15 because it's depreciating.

[tex] A = 25000(1 + \frac{-0.15}{1})^{1*5}[/tex]

[tex] A = 25000(1 - 0.15)^{5}[/tex]

[tex] A = 25000(0.85)^{5}[/tex]

[tex] A = 25000*0.4437[/tex]

A = 11092.63 ≈ $11093

Therefore, the future value, A after 5 years is $11093.

Answer:

Step-by-step explanation:

1.) 12-2/3x=48

2.) Multiple by 3 on both sides

36-2x=144

3.) Move the constant on the other side by subtracting it.

-2x=144-36

4.) Subtract numbers

-2x=108

5.) Divide both sides by -2

-2=108

÷2 ÷2

6) y = 55

7) no variable equals 101 in this triangle

Step-by-step explanation:

5) There was no question for 5

6) This is the answer because:

x = 79: 65+36+x = 180, 101+x = 180, x = 79

z = 144: 180 - 36 = 44

y = 55: 36+79+(y+10) = 180, 115+(y+10) = 180, y+10 = 65, y = 55

100 cups:$5.45
100 napkins:$2.09
10 invitations: $1.60
plastic punchbowl$11.50

Answers

Answer:

$2.58

Step-by-step explanation:

First, we should divide each number by 10 to get the amount per person we get...

10 cups

10 plates

20 balloons

Since the cost of cups, plates, and balloons is written as 100 of them, we just have to divide each of the by the amount we got after dividing by 10 and use that same amount and divide the money...

1. 10 cups is 1/10 of 100 cups so we divide $5.45 by 10 = .545

2. 10 plates is 1/10 of 100 plates so we divide $4.75 by 10 = .475

3. 20 balloons is 1/5 of 100 balloons so we divide $7.80 by 5 = 1.56

Now, we add them all up to get $2.58
