Answer:

The equation of the line is y = 7/2x + 8

Step-by-step explanation:

The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept.  To find m, you just have to subtract the two points from each other.

\frac{8 - 1}{0 - (-2)}   = 7/2

The y - intercept always has an x-value of 0, so the y-intercept would be 8.

So, the equation is y = 7/2x + 8

Isabella buys a digital camera and pays $7.20 in sales tax. The tax rate is 6%. What is the original cost of the camera?
Oksi-84 [34.3K]
<span>The original cost of the camera is $120.

Explanation:
6%=6/100=0.06. This means to find 6% tax on a sale, we multiply the amount of the sale by 0.06; this gives us 0.06x, since we don't know the cost of the camera.

We know the amount of tax is $7.20, so we have the equation 0.06x=7.20.

Divide both sides by 0.06:
0.06x/0.06 = 7.20/0.06
x=120.</span>

Vilka [71]

Answer:

Number of cookies produced in 8 hour are 10,600 cookies.

If the production rate of cookies in a bakery is 1325 cookies per hour, we need to tell how many cookies will be produced in 8 hour shift.

Number of cookies produced in 1 hour = 1325 cookies

Number of cookies produced in 8 hour = 1325 * 8

                                                                 = 10,600 cookies.

So, Number of cookies produced in 8 hour are 10,600 cookies.
