@tonypr_18

Answer 3

equation of a line is
y=mx+c

Answer 4

Huh

Answer 5

@random231

Answer 6

ur given equation of a line is
y=(1/5)x-2

Answer 7

so slope m=1/5

Answer 8

c=-2

Answer 9

can i ask another :)

Answer 26

12. Which function is a quadratic function? (1 point)
y = –3x2 + x
y = 2x – 1
y = 3 over x
y = –|x|

Answer 27

13. Mia charges $2.25 per hour when she babysits, plus $5.00 for transportation expenses. Which function rule represents the amount y Mia charges to babysit for x hours? (1 point)
y = 2.25x + 5.00
x = 5.00y + 2.25
y = 5.00x + 2.25
y = 7.25x

Answer 28

14. The sale price of apples at a local grocery store is $1.35 for the first pound and $1.10 for each additional pound. Which function rule shows how the cost of apples, y, depends on the number of pounds, x? (1 point)
y = 1.10(x – 1) + 1.35
y = 1.10x + 1.35
y = 1.35x + 1.10
y = (1.10 + 1.35)x

Answer 29

well what is a a quadratic well
A marathon of tension-filled reality shows can’t deliver the drama of quadratic functions. Peaks, valleys, hitting rock bottom – these plot twists do not exclusively belong to Hollywood. Quadratic functions depict the changing behavior of a set of data. Refer to the graph, Pop Star’s Record Sales.

Within 3 years after she inked her 1st record deal, the singer had sold over 15 million records in 1 year. Two years later, the pop fizzled and she sold zero records. Algebra can depict a rags to riches to rags spectacle better than any melodrama.
Characteristics of Quadratic Functions

1. Standard form is y = ax2 + bx + c, where a≠ 0.

2. The graph is a parabola, a u-shaped figure.

3. The parabola will open upward or downward.

4. A parabola that opens upward contains a vertex that is a minimum point.
A parabola that opens downward contains a vertex that is a maximum point.


5. The domain of a quadratic function is all real numbers.

6. To determine the range of a quadratic function, ask yourself
two questions:

Is the vertex a minimum or
maximum?
What is the y-value of the vertex?

If the vertex is a minimum, then the range is all real numbers greater than or equal to the y-value.
If the vertex is a maximum, then the range is all real numbers less than or equal to the y-value.

7. An axis of symmetry (also known as a line of symmetry) will divide the parabola into mirror images. The line of symmetry is always a vertical line of the form x = n, where n is a real number. Click More Images to view Parabola that opens upward. Its axis of symmetry is the vertical line x =0.

8. The x-intercepts are the points at which a parabola intersects the x-axis. These points are also known as zeroes, roots, solutions, and solution sets. Each quadratic function will have two, one, or no x-intercepts.

urm yea

Answer 38

The function rule C = 10n + 26 relates the number of people n who attend a small concert to the cost in dollars C of the concert. Make a table of the input/output pairs to show the cost if 27, 39, and 43 people attend. (3 points)
(explain

Answer 39

27 : $296
39 : $416
43 : $456

That's the table for the question above. ^

Answer 41

18. Explain how to write a function rule from the table below. Then write a function rule.

x 2 4 6
y 1 0 –1
(3 points)

Answer 42

First let us plot those points to check what kind of a function we need. Whether it has to be a linear or a quadratic function. In this case, it is linear. The linear function that best fits this relationship is y=2-0.5x.
