Mr. Tolin purchased a used car for $2,816, which was 12% off the asking price. What was the asking price of the used car?
Nina [5.8K]

Answer:

Original price= $3,200

Step-by-step explanation:

Giving the following information:

Purchase price= $2,816

Discount rate= 12% = 0.12

<u>To calculate the original price, we need to use the following formula:</u>

Original price= purchase price / (1 - discount rate)

Original price= 2,816 / 0.88

Original price= $3,200

Setler [38]

Answer:

28 degrees

Step-by-step explanation:

A triangle is always equal to 180 degrees so add the degrees together

40+2x+3x=180

40+5x=180

5x/5=140/5

x=28

From the set {6, 7, 11}, use substitution to determine which value of x makes the equation true.
kotykmax [81]
11 if you multiply 11 by both the number and and the variable you’ll get 11x-55=66. Add 55 to each side which will give you 121 then divide that by 11

(a) Derive an equation of the line passing through the points A(0, 545) and B(4, 726). (Let t be the independent variable and y
a_sh-v [17]

Answer:

The equation of the line is y=45.25t+545

Step-by-step explanation:

The general for of a line is:

y=mt+n       (1)

where:

m is the slope of the line and m is the intercept with the axis of the dependent variable, y in this case.

In order to obtain the value of the slope (m) we can use the corresponding slope formula:

m=\frac{y_{2}-y_1 }{t_2-t_1}         (2)

where t_1, t_2, y_1 and y_2 are the corresponding coordinates of the given points. In this case:

t_1=0\\t_2=4\\y_1=545\\y_2=726\\

Substituting these values in equation (2) we obtain:

m=\frac{726-545}{4-0}=\frac{181}{4}=45.25\\m=45.25

Hence, the line equation is now:

y=45.25t+n     (3)

Now to obtain the value of n you can follow two options:

  1. You can substitute one of your points, A or B, in equation (3). In this way, you will obtain an equation where the variable is n

Note that for this question, it is easier to select point A because of having the independent variable equals to zero t=0. Hence, substituting point A in equation (3):

45.25*0+n=545\\n=545

Therefore, the line equation is: y=45.25t+545

The second option to find n is to think of the meaning of the <em>intercept</em>. The <em>intercept </em>of a line is defined as the point in which the line crosses the axis of the dependent variable, which also means that the value of the independent variable for this point is zero. From this, we could have automatically said that n is equal to 545.

See the attachment for a plot of the line.
