The line that passes through the points (-6, p) and (-10, 2) has a slope of -1/6. What is the value of p?
yaroslaw [1]
<h3>Answer:  4/3</h3>

Work Shown:

Slope = rise/run

Slope = (change in y)/(change in x)

Slope = (2-p)/(-10-(-6))

Slope = (2-p)/(-10+6)

Slope = (2-p)/(-4)

Set this equal to the stated slope -1/6 and solve for p

(2-p)/(-4) = -1/6

6(2-p) = -4(-1)

12-6p = 4

-6p = 4-12

-6p = -8

p = -8/(-6)

p = 4/3

G(x) = 3x^2 + 10x-8<br> Use the drop-down menus to factor the expression and find the zeros of g(x).
REY [17]

Answer:

g(x) = (3x - 2)(x + 4)

x = {-4, 2/3}

Step-by-step explanation:

g(x) = 3x^2 + 10x - 8

Factor

g(x) = (3x - 2)(x + 4)

Zero I

3x - 2= 0

3x = 2

x = 2/3

Zero II

x + 4 = 0

x = -4

x = {-4, 2/3}
