Lina20 [59]

Answer:

2 and 4.

Step-by-step explanation:

(x+2)^2 - x^2 = 12

x^2 + 4x + 4 - x^2 = 12

4x + 4 = 12

4x = 8

x = 2.

Hence the integers are 2 and 4.

What is the equation in point -slope form of a line that passes through the points (7,-8) and (-4,6)? A. y-6=-2/3(x+4) B. y+6=-1
Lapatulllka [165]
Given two points  (x₁,y₁) and (x₂,y₂)the slope passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)

In this case the slope will be:
(7,-8)
(-4,6)
m=(6+8)/(-4-7)=14/-11=-14/11

point-slope form of a line: we need a point (x₀,y₀) and the slope (m).
y-y₀=m(x-x₀)

In this case, we know the slope (m=-14/11), and we can choose either of two points. The line will be the same.

(-4,6)
m=-14/11
y-y₀=m(x-x₀)
y-6=-14/11(x+4)        ⇒ (point-slope form)

<span>Answer:  D.  y-6=-14/11(x+4)</span>

Expand 2(m+5)+4(m-6)
Vlad1618 [11]

Answer:

6m - 14

Step-by-step explanation:

2(m + 5) + 4(m - 6) \\  = 2m + 10 + 4(m - 6) \\  = 2m + 10 + 4m - 24 \\ =  (2m + 4) + (10 - 24) \\  = 6m - 14
