Find the difference. (-5ab+6a-1)-(-5ab-8)

Mathematics
1 answer:
vovangra [49]3 years ago
7 0

Answer:

6a - 9

Step-by-step explanation:

First off, let's put all of the identical variables besides each other, to make this equation easier.

-5ab - (-5ab) + 6a - 8 - 1

Then, we simply solve.

-5ab + 5ab = 0

6a = 6a

-8 - 1 = -9

So you're left with 6a - 9 as your answer.

Hope that helps!

The Table Shows a proportional relationship between x and y for each Value of x and y match it to the correct unit rate y/x in i
Elden [556K]

The correct proportions are given as follows:

  • x = 3, y = 27: 9/1.
  • x = 9, y = 81: 9/1.
  • x = 21, y = 126: 6/1.
  • x = 14, y = 84: 6/1.
  • x = 12, y = 36: 3/1.
  • x = 15, y = 45: 3/1.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The proportions for this problem are given dividing y by x, hence:

  • x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
  • x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
  • x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
  • x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
  • x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
  • x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.

Find the slope using the formula LaTeX: \frac{y_2-y_1}{x_2-x_1}y2−y1x2−x1 (9, 10) and (7, 2)
guapka [62]

Answer:

<h2>slope = 4</h2>

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (9, 10) and (7, 2).

Substitute:

m=\dfrac{2-10}{7-9}=\dfrac{-8}{-2}=4
