198 = -4x + 2(-6x+3)

1 answer:

4 0

198=-4x+2(-6x+3), 198=-4x-12x+6, 198=-16x+6, collect the like terms, 198-6=-16x, 192=-16x, divide both sides by -16, 192/-16=-16x/-16, x=-12

Answer:

My guess is $29

Step-by-step explanation:

So first I take the difference of the 10th and 6th month, which is 116.

I take that and divide it by 4, because that was the change in 4 months(10-6)

116÷4=29

Check the picture below.

recall the ambiguous SSA case, as the "12" side moves, it ends up with two supplementary angles on the base.

Find two "dots" where the line crosses the X and Y axis at real numbers.

(0,3) and (6,-1)

Now find the slope which is the difference in Y over the difference in x.

Slope = (-1 - 3) / (6-0) = -4 / 6 = -2/3

The answer is D.

X^2 + 3x - 4 = 6

x^2 + 3x -10 = 0

(x + 5)(x - 2) =0

x = -5 or x = 2

solution set is {-5,2}
