If you are to distribute then the answer would be 12x+6. Because 3(4x−(−2))

=(3)(4x+2)

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

=12x+6.

What is the equation of the line that passes through the point (-4, -6) and has a slope of -1/2?

Sedaia [141]

Point slope form

y - -6 = (-1/2)(x - -4)

y + 6 = (-1/2)x - 2

y = (-1/2)x - 8

Answer: y = (-1/2)x - 8

Check. Clearly slope is -1/2, good. (-1/2)(-4)-8=2-8=-6 good

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

Rufina [12.5K]

Local Calls = 36

In short, Your Answer would be Option A

Hope this helps!
