Vertex x = -b/2a so x = 1/2. Plug in x and u get 3/2

Vertex = (.5, 1.75)
First, you must find your x-value, which is represented by h in the formula h=-b/2a. In this equation, A = 1, B = -1, C = 2, which gives you -1(-1)/2(1) = 1/2 = .5. Now that you know your x-value is .5, you can solve for y. Plug in your x-value accordingly: (.5)^2-.5+2 = 1.75. x = .5, y = 1.75, therefore, your vertex is (.5,1.75)

(9 x 10) + (20x + 21) = 571<br><br> What does (x) equal
creativ13 [48]
(9 × 10) + (20x + 21) = 571
90 + 20x + 21 = 571
111 + 20x = 571
- 111
20x = 460
÷ 20
x = 23

Please answer them. 25 points.
diamong [38]

Step-by-step explanation:

<u>Initial value is the y-intercept:</u>

  • b = 1200

<u>Rate of change is the difference in the charge amount per year:</u>

  • m = (1350 - 1200) / (8 - 5) = 150 / 3 = 50

<u>The equation would be:</u>

  • y = 50x + 1200

What is the solution set of the equation 6x^2 - 18x - 18 =6?
dybincka [34]

Answer:

The solution set is {4, -1}

Step-by-step explanation:

6x²- 18x -18 = 6

6x²- 18x -18 - 6 = 0

6x²- 18x -24 = 0

6(x² - 3x - 4) = 0

6(x - 4)(x + 1) = 0

6 = 0 not true

x - 4 = 0 ;   x + 1 = 0

x = 4           x = - 1

The solution set is {4, -1}
