The function h(x) = –2x2 + 8x written in vertex form is h(x) = –2(x – 2)2 + 8. The function h(x) is shown on the graph along with the parent function, f(x) = x2.Which statement is true concerning the vertex and axis of symmetry of h(x)?

The vertex is at (0, 0) and the axis of symmetry is x = 2.
The vertex is at (0, 0) and the axis of symmetry is y= 2.
The vertex is at (2, 8) and the axis of symmetry is x = 2.
The vertex is at (2, 2) and the axis of symmetry is y = 2.

Answers

Answer 1

Answer: The general vertex form of a quadratic function is this: h(x) = -a(x-h) + k.
The vertex is at (h,k) and the axis of symmetry is at x=h.

Using this, the true statement among the choices is this:
The vertex is at (2, 8) and the axis of symmetry is x = 2.

Answer 2

Answer:

Answer: C. The vertex is at (2, 8) and the axis of symmetry is x = 2.

the coordinates of the endpoints of line AB and line CD are A(x1, y1), B(x2, y2), C(X3,Y3), and D(x4, y4). which condition proves that line AB is parallel the CD?

Answers

Find the slope for the two lines and state that they are equal (condition for parallel lines)

Slope of line AB

[y2 - y1] / [x2 - x1]

Slope of line CD

[y4 - y3] / [x4 - x3]

Condition

[y2 - y1] / [x2 - x1] = [y4 - y3] / [x4 - x3]

Problem 2

Midpoint: Think 1/2. A midpoint cuts a line segment in 1/2 (in this question). That means that the left segment = the right segment. Remember: midpoint means 1/2.

LN is given as 14.

LM is 1/2 the distance of 14

LM = 1/2 * 14

LM = 7

Problem 3

If the midpoint = the 1/2 way point, the two halves are equal. Remember a midpoint divides the 2 parts into 2 EQUAL parts.

4a - 2 = 18 Add 2 to both sides

4a = 18 + 2

4a = 20

a = 20 /4

a = 5

Problem 4

Remember that midpoint means 1/2. That a midpoint cuts a segment into 2 equal segments

Equation

2n + 2 = 5n - 4

Solve

2n + 2 = 5n - 4 Add 4 to both sides

2n + 2 + 4 = 5n Subtract 2n from both sides.

6 = 5n - 2n

6 = 3n Divide both sides by 3

6/3 = n

n = 2

Answer: B

Problem 5

And again the whole line segment is divided into 2 equal parts.

Equation

6p - 12 = 4p Add 12 to both sides

6p = 12 + 4p Subtract 4p from both sides.

6p - 4p = 12

2p = 12 Divide by 2

p = 12/2

p = 6 <<<<< Answer

A greenhouse that specializes in growing carnations is divided into sections. The number of plants in each section depends on the number of sprinklers in that section.There are y(5y − 4) red carnation plants and (9 + y)2 white carnation plants in a section with y sprinklers.

Which simplified expression represents the total number of red and white carnation plants in a section with y sprinklers?
5y2 + 18y +77
5y4 + 14y + 81
6y2 + 14y + 81
6y2 + 18y + 77

Answers

Answer:

C. $6y^2+14y+81$

Step-by-step explanation:

We have been given that the expression $y(5y-4)$ represents number of red carnation plants and expression $(9+y)^2$ represents number of white carnation plants in a section with y sprinklers in a green house.

To find the simplified expression that represents the total number of red and white carnation plants in a section with y sprinklers, we will add our both expressions.

$y(5y-4)+(9+y)^2$
