Answer:

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

     = - 2(x + 3)² + 18 - 16

     = - 2(x + 3)² + 2 ; y = 2

Answer:

A. x = 6.08, x = -0.58

Step-by-step explanation:

[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{x^2-10x+24}=\frac{-3}{x-6}[/tex]

1. Factor the denominator.

[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]

2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.

[tex]\displaystyle \Big ( \frac{x-6}{x-6} \Big ) \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]

3. Simplify.

[tex]\displaystyle \frac{2x^2-12x}{(x-4)(x-6)}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]  

4. Combine like terms.

[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6}[/tex]  

5. Multiply the right side of the equation by (x-4)/(x-4).

[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6} \Big ( \frac{x-4}{x-4} \Big )[/tex]  

6. Simplify.

[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3x+12}{(x-6)(x-4)}[/tex]

7. "Cancel" out the denominators because they are equivalent.

[tex]2x^2-14x+5=-3x+12[/tex]

8. Set the equation equal to 0.

[tex]2x^2-11x-7=0[/tex]

Quadratic formula:

[tex]\displaystyle x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]  

9. Factor using the quadratic formula.

[tex]\displaystyle x = \frac{-(-11)\pm \sqrt{(-11)^2-4(2)(-7)} }{2(2)}[/tex]

10. Multiply and simplify.

[tex]\displaystyle x = \frac{11 \pm \sqrt{177} }{4}[/tex]

11. Plug this into your calculator and solve for x.

[tex]x=6.07603367 \approx 6.08[/tex] [tex]x=-0.57603367 \approx -0.58[/tex]

The correct answer is A. x = 6.08, x = -0.58.

Who can help me on my math I’m failing can y’all please help me on some questions.
It’s solving systems of equations

Answers

Answer:

7 quarters, 8 nickels

Step-by-step explanation:

So the system of equations you have is:

x + y = 15

0.25x + 0.05y = 2.15

Here's how to solve:

first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:

25x + 5y = 215

Then, you can divide both sides by 5 to simplify it more:

5x + y = 43

Now, you have the system of equations:

5x + y = 43

x + y = 15

Now subtract the two equations:

4x = 28

divide both sides by 4

x = 7

plug x = 7 into the equation x + y = 15 to solve for y:

7 + y = 15

subtract 7 from both sides

y = 8

So you know that there are 7 quarters and 8 nickels.

Find the inequality represented by the graph.

Answers

Answer:

y > 1/3 x - 3

Step-by-step explanation:

First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).

Find the change of y over the change of x to get the slope of the line.

(-2 - (-3))/(3 - 0) = 1/3

Since the line intercepts the y axis at (0, -3), the equation of the line would be

y = 1/3x - 3

We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents

y > 1/3 x - 3

A cylinder has a base diameter of 20in and a height of 17in. What is its volume in cubic in, to the nearest tenths place?

volume = area of base * height

volume = 3.1415 * 10^2 * 17

The volume of the cylinder is 533.8 cubic inches to the nearest tenths place

Volume of Cylinder based problem:

What information do we have?

Diameter of cylinder = 20 inch

Height of cylinder = 17 inch

Volume of Cylinder = πr²h

Volume of Cylinder = (3.14)(20/2)²(17)

Volume of Cylinder = (3.14)(10)(17)
