What the answer to this equation be?

If you expand the square, you have

\dfrac{1}{4}x^2-3x=7x+8-10x

Simplify the right hand side:

\dfrac{1}{4}x^2-3x=-3x+8

Cancel the -3x appearing on both sides:

\dfrac{1}{4}x^2=8

Multiply both sides by 4:

x^2=32

Consider the square root of both terms (using the doubles sign):

x=\pm\sqrt{32}=\pm4\sqrt{2}

I need help with this problem down below
Misha Larkins [42]

Answer:

y = 4

Step-by-step explanation:

Given:

y = \frac{7x + 1}{3x - 6},

To find the value of y, let's find x by solving 3x = 15.

3x = 15

Divide both sides by 3

x = 15/3

x = 5

Plug in the value of x into y = \frac{7x + 1}{3x - 6}

y = \frac{7(5) + 1}{3(5) - 6}

y = \frac{35 + 1}{15 - 6}

y = \frac{36}{9}

y = 4

Because the vertex of the parabola is at (16,0), its equation is of the formy = a(x-10)² + 15
The graph goes through (0,0), thereforea(0 - 10)² + 15 = 0100a = -15a = -0.15
The equation is y = f(x) = -0.15(x - 10)² + 15
The graph is shown below.
Part A
Note that y = f(x).
The x-intercepts identify values where the function or  y=0. The x-intercepts occur at x=0 and x=20, or at (0,0) and (20,0).
The maximum value of y occurs at the vertex (10, 15) because the curve is down due to the negative leading coefficient of -0.15.
The curve increases in the interval x = (-∞, 10) and it decreases in the interval x = (10, ∞).
Part B
When x=12, y = -0.15(12 - 10)² + 15 = 14.4When x=15, y = -0.15(15 - 10)² + 15 = 11.25
The average rate of change between x =12 to x = 15 is(11.25 - 14.4)/(15 - 12) = -1.05
This rate of change represents the slope of the secant line from A to B. It approximates the rate at which f(x) decreases in the interval x =[12, 15].
