Use slope formula to find the missing coordinate. (r, 1) and (5, -7) Slope = 8/3

Lena [83]

Answer:

r=8

Step-by-step explanation:

The formula for slope is

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

Substitute in what we know.

8/3 = (-7-1)/(5-r)

Simplify

8/3 = -8/(5-r)

We can use cross products to help us solve.

8 * (5-r) = 3 * (-8)

divide each side by 8

8/8 * (5-r) = 3 * (-8)/8

5-r = -3

Subtract 5 from each side

5-r-5 = -3-5

-r = -8

Multiply by -1

r = 8

∑ Hey, jillianwagler ⊃

Answer:

$\left(2x-1\right)\left(2x+5\right)$

Step-by-step explanation:

║Given info║:

Factor completely: $4x^2 +8x -5$

Solution~:

Breaking the expression~: $\left(4x^2-2x\right)+\left(10x-5\right)$

Factor out 2x from 4x² -2x : 2x(2x-1)

Factor out 5 from 10x - 5 : 5(2x - 1)

Put together: $=2x\left(2x-1\right)+5\left(2x-1\right)$

Factor out 2x - 1: $=\left(2x-1\right)\left(2x+5\right)$
