At the very least 42.15 x 2 = 84.30 + 20 =104.30 + taxes
-1/4 because you have to do ride over run which is y2-y1 divided by x2-x1. Then you get your answer.
Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>
We can easily silve it by splitting the middle term or by using the discriminate method *
<h3>* <u>splitting</u></h3>
x 2 +3x -70
x2 + 10x - 7x -70
x(x + 10) -7(x +10)
(x / 7) ( x + 10)
x = 7 or -10
