A store is having a 20%-off sale on all merchandise.

lyudmila [28]

This is easy . There is a 20 percent discount which means now it’s only (100-20%) discount.
This is 80% discount.
Money saved is equal to 100-80%
=20%
And that 20% is equal to 13$ as per the passage.
So now we need to calculate 1 percent of the item without discount .
This is equal to 13/20
This is equal to .65
Now to find the original price you will need to multiply .65 to 100 this is equal to 65$.

Hey guys!

GaryK [48]

The value of c from the given expression is -

<h3>Function and values</h3>

Given the following function

c(n)= −c(n−1)+1

Given the following parameters

c(1)=3

Substitute

3 = −c(3−1)+1

3 = -2c + 1

-2c = 3-1

-2c = 2

c = -1

Hence the value of c from the given expression is -1

Choose the equation that has solutions (5,7) and (8,13).

Alekssandra [29.7K]

<h2>Answer:y=2x-3</h2>

Step-by-step explanation:

$(x_{1},y_{1})$ is called solution of a equation if $(x_{1},y_{1})$ satisfies the equation.

Consider the equation $y=2x-3$ ,

For point $(5,7)$ ,

$LHS=y=7$

$RHS=2x-3=2(5)-3=10-3=7$

So, $RHS=LHS$

The point $(5,7)$ satisfies the equation.

For point $(8,13)$ ,

$LHS=y=13$

$RHS=2x-3=2(8)-3=16-3=13$

So, $RHS=LHS$

The point $(8,13)$ satisfies the equation.

So,both the points satisfy the equation $y=2x-3$

Angelique is thinking about buying a house for $179,000. The table below shows the projected value of two different houses for t

marusya05 [52]

Answer:

A) both functions are linear

B) f(x) = 7446.4x + 178713.6 and f(x) = 11000x + 179000

C) House 2 will value $106894.4 more than house 1.

Step-by-step explanation:

A) Value Increase from year 1 to year 2:

House 1: 193,606.40 - 186,160 = 7446.4

House 2: 201,000 - 190,000 = 11000

Value Increase from year 2 to year 3:

House 1: 201,350.66 - 193,606.40 = 7744.26

House 2: 212,000 - 201,000 = 11000

This means that a constant increament in x variable gives a constant increament in both houses vales. Then, both functions are linear.

B) The slope is the same as the value increment from one year to the next one.

slope (m) of House 1: 7446.4

slope (m) of House 2: 11000

General formula of a line:

f(x) = mx+b

Replacing with a known point:

<u>House 1</u>

186,160 = 7446.4(1) + b

b = 186,160 - 7446.4 = 178713.6

equation: f(x) = 7446.4x + 178713.6

<u>House 2</u>

190,000 = 11000(1) + b

b = 190,000 - 11000 = 179000

equation: f(x) = 11000x + 179000

C) Replacing x = 30 into each equaiton:

<u>Value of House 1 after 30 years</u>

f(x) = 7446.4(30) + 178713.6 = 402105.6

<u>Value of House 2 after 30 years</u>

f(30) = 11000(30) + 179000 = 509000

Then, house 2 will value 509000 - 402105.6 = $106894.4 more than house 1.
