Step-by-step explanation:
Which of the following is the correct equation for this function?
A. v=2x² + x - 2
B. v= 2x^2 - 4x
C. 1= (x+1)(x-2)
D. V+1=2(x - 3)^2
Answer:
B. y = 2x^2 - 4x
Step-by-step explanation:
The point (0, 0) lies on the graph, so the equation has no constant term (the constant is zero). Only one answer choice has this characteristic:
y = 2x^2 -4x
What is the equation of the line in slope intercept form? Help 30 points!
Answer:
y = 2/3x - 7
Step-by-step explanation:
(3, -5) (-3, -9)
and y = -7 when x = 0 from graph
so c = -7
m = -9 - (-5) / -3 - 3
= -4 / -6
= 2/3
line equation is y = mx + c
y = 2/3 x + (-7)
y = 2/3x - 7
[tex]\\ \sf\longmapsto m=\dfrac{-9+5}{-3-3}[/tex]
[tex]\\ \sf\longmapsto m=\dfrac{4}{6}[/tex]
[tex]\\ \sf\longmapsto m=2/3[/tex]
b=-7Now
Equation of line

How does the equation of a quadratic function in vertex form highlight key features of the function’s graph?
9514 1404 393
Explanation:
Vertex form of a quadratic can be written as ...
a(x -h)² +k = 0 . . . . . . vertex (h, k); scale factor 'a'
First of all, it highlights the vertex (x, y) = (h, k), which is the extreme maximum or minimum of the function. That also tells you the axis of symmetry, (x = h).
Vertex form also shows you the vertical scale factor. The sign of that tells you whether the graph opens upward (positive) or downward (negative). The numerical value of it tells you the vertical distance from the vertex to points ±1 unit either side of the vertex.
The roots of the quadratic will be ...
x = h ±√(-k/a)
These will be complex if the graph does not intersect the x-axis.
Answer:
From the vertex form ()=(−)+ , you can find the vertex (,) and see whether the parabola opens upward (if > ) or downward (if < ). From a graph, you can read the coordinates of the vertex and substitute into the vertex form. With the coordinates of one other point, you can solve the equation to find a and write the equation of the quadratic function in vertex form.

Which of the following describes the parabola with the equation y = −x2 − 3x + 6?
A. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
B. The axis of symmetry is x = 1.5 and the vertex is (1.5, 12.75).
C. The axis of symmetry is x = −1 and the vertex is (−1, −3).
D. The axis of symmetry is x = 0 and the vertex is (0, 6).
Answer:
B. The axis of symmetry is x = 1.5 and the vertex is (1.5, 12.75).
Step-by-step explanation:
I will solve the problem by applying the perfect square trinomial. In this way we obtain the canonical form. Another way would be to derive the function, but I don't know if you're familiar with it.
First: let us take out the common factor: , since we remember that the canonical form is characterized as follows:
Then, it remains:
Then: the coefficient of the variable We divided it between , And we square it (they will be one positive and one negative). In our case:
Let's accommodate terms to make it easier:
Can be written as :
Now, what is underlined is our perfect square trinomial, let us recall its form:
Applying the same principle we are left:
Applying distributive property we get:
Therefore it will have its vertex in:
The axis of symmetry is a straight line that makes the function to be projected being , for this you need some reference point, for the parabola you need the coordinate in of the vertex.
For which the axis of symmetry is .
-1.5

The fee for a cleaning service is described in the table below.
Write an equation to represent the data in the table.
Answer:
y=16x+36
Step-by-step explanation:
cleaning services start at $36 for one hour and add $16 to total price per hour.
16(1)+36=52
16(2)+36=68
16(3)+36=84
16(4)+36=100
RS = 2x + 10
ST = x - 4
RT = 21
Answer:
x = 5
Step-by-step explanation:
RS +ST = RT
2x + 10 + x - 4 = 21
2x + x + 10 - 4 = 21 {Combine like terms}
3x + 6 = 21
Subtract 6 from both sides
3x = 21 - 6
3x = 15
Divide both sides by 3
x = 15/3
x = 5

1. Describe the difference between a relation and a function.
Answer:
The difference between a relation and a function is that a relationship can have many outputs for a single input, but a function has a single input for a single output. This is the basic factor to differentiate between relation and function. Relations are used, so those model concepts are formed.

Answer:
Discount: $2.10
Final Cost: $11.90
Step-by-step explanation:
14 times 15% is 2.10.
So, you would take that $2.10 and subtract it from $14.00 to get your answer of $11.90
Please explain step by step.
(Good answers with good explanation only please.)
Answer:
A
Step-by-step explanation:
x= total number of sets bought
y= total cost
Since each set costs 3 dollars, we can represent that with the equation y=3x, and the teacher also had a 2 dollar coupon, so we can subtract 2 from the equation, giving us y=3x-2
So, by looking at the charts, plug in x (the input), and see if the y (output) is the same as the equation represents.
So, the answer is A. To test, plug in the x and see if it gives the right y.
For example, 3 sets bought (x), so it will be represented as,
y=3x-2
y=3(3)-2
y=7
So when 3 is x, y is 7. Which is what answer choice A shows.
