To find slope, we must find the change in y values divided by the change in x values, also called the rise/run. This is modeled below:

Slope = m = (y1 - y2)/(x1-x2) = (6-(-3))/(1 - (-6)) = (6+3)/(1+6) = 9/7

We can check that this answer is correct by consulting the graph. The graph shows a positive correlation (means that the slope should be positive), and if you count the graph unit squares, you get that the graph moves up 9 squares and over 7 squares between the two points shown, letting us know we got the right answer.

Hope this helps!

How can you tell if the expression 7x-4 and 6x-4-x are equivalent

olga_2 [115]

Answer:

see below

Step-by-step explanation:

7x-4 6x-4-x

Combine like terms on the second expression

7x -4 6x -x -4

5x -4

These are not equivalent expressions

7x -4 does not equal 5x-4

"5. Multiple-choice questions each have five possible answers (a,b,c,d,e), one of which is correct. Assume that you guess the an

Nina [5.8K]

Answer:

A) P(WWC) = 0.128

B) P(WCC) = 0.032

P(CWC) = 0.032

P(CCW) = 0.032

C) probability of getting 2 correct answers when 3 guesses are made is i.e P (1 wrong and 2 correct) = 0.064

Step-by-step explanation:

A) Using the multiplication rule, we have; P(A and B) = P(A) x P(B)

Probability of a wrong answer = 4/5 = 0.8

Probability of a correct answer = 1/5 =0.2

Thus; P(WWC) = 0.8 x 0.8 x 0.2 = 0.128

B) Beginning with one wrong and two correct answers, a complete list of all possibilities is;

P(WCC), P(CWC), P(CCW)

Hence the complete list is;

(0.8 x 0.2 x 0.2); (0.2 x 0.8 x 0.2); (0.2 x 0.2 x 0.8)

So we have;

P(WCC) = 0.032

P(CWC) = 0.032

P(CCW) = 0.032

C) Based on the results above, the probability of getting 2 correct answers when 3 guesses are made is i.e P(1 wrong and 2 correct) = 2 x 0.032 = 0.064

Which is not a valid way to determine the perimeter of a rectangle with side lengths of 18 inches and 22 inches?

Andreyy89

Answer:

P = 2(18) + 22

Step-by-step explanation:

The formula for the perimeter for a rectangle is P = 2(l + w). Take this equation and expand to find its equivalents.

P = 2(l + w) This is P = 2(18 + 22)

P = 2l + 2w This is P = 2(18) + 2(22)

P = l + l + w + w This is P = 18 + 22 + 18 + 22

It is only P = 2(18) + 22 that is not equal to the others. It does not have the fourth side of 22.
