Answer:

-0.5

Step-by-step explanation:

For an increase of 1 in x (as from 1 to 2, for example), the corresponding change in y-value is -0.5 (as from 0 to -0.5, for example).

The slope is the ratio of these changes:

-0.5 / 1 = -0.5 . . . . slope of the relation in the table

15. A rectangle has a length of 2x - 1 and a width of 3x + 7. Find the perimeter of this rectangle.

andrew11 [14]

Answer:

10x + 12 and 6x² + 11x - 7

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is length and w is width )

= 2(2x - 1) + 2(3x + 7) ← distribute parenthesis

= 4x - 2 + 6x + 14 ← collect like terms

= 10x + 12

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

The area (A) of a rectangle is calculated as

A = lw

= (2x - 1)(3x + 7) ← expand using FOIL

= 6x² + 14x - 3x - 7 ← collect like terms

= 6x² + 11x - 7

P − 10p + -5p + 14p − -9p − 2 = -20

djverab [1.8K]

You will need to work left to right.

p - 10p + -5p +14p - -9p - 2 = -20

-9p + -5p +14p - -9p - 2 = -20

-14p +14p - -9p - 2 = -20

0p- -9p - 2 = -20

9p - 2 = -20

Then you will want to eliminate 2 by adding it to both sides

9p = -18

Then divide by 9 to isolate P

p=-2

Which choice shows the result of substituting 3x – 5 into the second equation for y?

ahrayia [7]

Answer: The answer is (B) 2x + 3(3x – 5) = 51 .

Step-by-step explanation: We are given three options and we are to select which choice shows the result of substituting 3x – 5 into the second equation for y.

So, y = 3x - 5.

Since the standard form of a linear equation i two variables is ax + by = c, so the second equation as given in the options must be of the form 2x + 3y = 51.

If we substitute y = 3x - 5, then this equation becomes

2x + 3(3x - 5) = 51.

Thus, (B) 2x + 3(3x – 5) = 51 is the correct option.
