Find the slope (0, -3) and (9, 0) PLEASE SHOW YOUR WORK, WILL MARK BRAINLEIST

<h3>Answer: slope = 1/3</h3>

===================================================

Work Shown:

Use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (0 - (-3))/(9 - 0)

m = (0 + 3)/(9 - 0)

m = 3/9

m = 1/3

----------------

Basically we subtract the y coordinates, and do the same for the x coordinates as well (subtract in the same order). Afterward, divide the two results. Reduce the fraction as much as possible.

A slope of 1/3 means we move up 1 unit each time we move to the right 3 units.

The slope being positive means the line goes uphill as you read from left to right.

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?
Vera_Pavlovna [14]

Answer:

(-8, 0), (0,0) and (7, 0)

Step-by-step explanation:

When f(x) = 0 the curve of f(x) intercept x-axis, that is, y = 0. This points are called roots or zeros of the polynomial.

From the picture, we can see that f(x) = 0 at points (-8, 0), (0,0) and (7, 0)

How many gallons of pure water should be added to 10 gallons of a solution containing 15% juice so that the remaining solution c
jok3333 [9.3K]

Answer:

20 gallons

Step-by-step explanation:

10 gallons of solution w/ 15% juice means 1.5 gal of juice

to make it into 5%, multiply 1.5 by 20

1.5 x 20 = 30

5% of 30 gallons is 1.5 since 10% of 30 is 3.

Since there was already 10 gallons, the # of gallons of pure water added should be 20 gal.

I hope this helps thanks
