Answer:

y = - 8x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 8 , then

y = - 8x + c ← is the partial equation

To find c substitute (9, - 73 ) into the partial equation

- 73 = - 72 + c ⇒ c = - 73 + 72 = - 1

y = - 8x - 1 ← equation of line

Jenny bought 3 CDs that were each the same price. Including sales tax, she paid a total of $45.30 Of that total, $1.50 was tax.

enot [183]

Answer:

$13.6

Step-by-step explanation:

Jane bought 3 CDs that were each the same price. So let the price of each CD be ‘x’.

It is given that including sales tax, she paid a total of $45.30.

Also each CD had a tax of $1.50. We need to find out what the price of each CD was before tax.

Since the tax for all 3 CDs was same, the total amount of tax that she paid was:

3 * 1.50 = 4.50

Therefore the total tax on 3 CDs is $4.50

Since we already know the total price she paid for the CDs including taxes, we can find the price of each CD by the following way:

3x + 4.50 = 45.30

3x = 45.30 - 4.50

3x = 40.8

x = 13.6

Therefore the price of each CD before tax is $13.6.

2 5/8 as a rational number ??

arlik [135]

Answer:

It's already a rational number?

Step-by-step explanation:

A rational number is any number that can be written as a fraction/ratio, and $2\frac{5}{8}$ is certainly a fraction. If you meant $2\frac{5}{8}$ as a decimal, then it'd be 2.625.
