Not sure how I would solve this

<h3>Answer:   -6/5</h3>

Explanation:

The blue diagonal line goes through the two points (0,2) and (5,-4). These are shown as the dark blue enlarged points. You can pick any other points you want that are on the diagonal line, though these are the easiest as they stand out the most.

Use the slope formula to find the slope through these points

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

m = (-4-2)/(5-0)

m = (-6)/(5)

m = -6/5

The negative slope means the line goes downhill as you move from left to right along the diagonal line.

Is 18-3(2p+4) -3p equivalent to 3(2-3p)
Murljashka [212]

Answer:

<u>Yes they are equivalent.</u>

Step-by-step explanation:

Use PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

Distribute or multiply -3 with 2p and 4 to get -6p and -12.

You will then have 18-6p-12-3p, simplify to get 6-9p

For the second equation multiply 3 with 2 and -3p, you will then get 6-9p as well.

They are equal, hope the helps ;)
