Answer:

\boxed {m = -\frac{3}{4}}

Step-by-step explanation:

Use the <u>Slope Formula</u> to help you determine the slope of two given points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

First point: (x_{1}, y_{1})

Second point: (x_{2}, y_{2})

-Substitute both given points onto the formula:

First point: (1, 2)

Second point: (-3, 5)

m = \frac{5 - 2}{-3 - 1}

-Solve for slope:

m = \frac{5 - 2}{-3 - 1}

m = \frac{3}{-4}

\boxed {m = -\frac{3}{4}}

Therefore, the slope is -\frac{3}{4}.

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

-4x - 2 = -18 POR FA AYUDENME
charle [14.2K]

Answer:

The answer is x=4

Step-by-step explanation:

so you have -4x-2=-18

so we get rid of -2 by adding it to the other side so you'll end up having -4x=-16

you then divide that by -4 on both sides and get x=4 as your remaining answer
