The table C is a linear function
For a function to be a linear function, then the x and the y values must change at a constant rates.
From the question, as the x values of table C constantly change by 1, the y values constantly change by -2
This means that the table C is a linear function

The table shown in option 3 represents a linear function with a constant rate of - 3. Hence option 3 is true.
Used the concept of the linear function that states,
If a function has a constant average rate of change, the function is called a linear function.
Given that,
There are four tables shown in the image.
Now apply the formula for the rate of change with two points (x₁, y₁) and (x₂, y₂),
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
From the third table,
Take two points (1, - 3) and (2, - 5).
Hence the rate of change is,
[tex]m = \dfrac{(- 5 + 3)}{(2 - 1)}[/tex]
[tex]m = \dfrac{- 2}{1}[/tex]
[tex]m = - 2[/tex]
Take two points (2, - 5) and (3, - 7).
Hence the rate of change is,
[tex]m = \dfrac{(- 7 + 5)}{(3 - 2)}[/tex]
[tex]m = \dfrac{- 2}{1}[/tex]
[tex]m = - 2[/tex]
Therefore it shows the constant rate.
Hence option 3 is true.

Step-by-step explanation:
It is a parallelogram so the opposite angles are the same.
All angles sum to 360 degrees.
This means that the adjacent angles sum to 180 degrees.
4a + 11 + 9a = 180 = 13a + 11
13a = 169

Answer(s):
y = 2(x - 1)2 + 3
y = 2(x2 - 2x + 1) + 3
y = 2x2 - 4x + 2 + 3
y = 2x2 - 4x + 5
Answer:
y = -3/4(x + 2)² + 6Step-by-step explanation:
Vertex form of quadratic function:
y = a(x - h)² + kGiven a graph with:
Vertex = (-2, 6)Points: (-6, -6), (2, -6)We can see that:
h = -2 and k = 6, a is negative (parabola opens down)The equation becomes:
y = a(x + 2)² + 6Substitute coordinates (-6, -6) into the equation to find the value of a:
-6 = a(-6 + 2)² + 6-6 = 16a + 616a = -12a = -12/16a = -3/4The function becomes:

Find the measure of each interior angle.
Answer:
d. m<R = 128, m<S = 52, m<T = 128, m<U = 52
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 360°
6x - 4 + 2x + 8 + 2x + 8 + 6x -4 = 360° add like terms
16x + 8 = 360 subtract 8 from the both sides
16x = 352 divide both sides by 16
x = 22 now to find the value of each angle replace x with 22

Jordan walks 250 m North towards school. He forgets his backpack and walks 250 m South back to his house. He then finds his backpack and walks 900 m North. He gets to school in 9 minutes. What is his velocity in meters per minute
Answer:
10 m / minute
Step-by-step explanation:
Starting position = North ; back to North gives a Displacement of 0 ; the from that position to 900 m south gives a final Displacement of 900
Displacement / time
Displacement = 900
Time = 9 minutes
900 / 9
= 10 m / minute

When Groundhog Day is
on a weekday,
around15,000 people
attend the events in
Punxsutawney, PA. If two-
thirds take the shuttle bus
to the park for $5 and the
rest pay $25 for parking,
how much money does
the city earn?
====================================================
Work Shown:
2/3 of 15,000 = (2/3)*15000 = 10,000
This means 10,000 people take the shuttle bus to the park. If each person pays $5 to take the bus, then the city earns 5*10,000 = 50,000 dollar through this option.
The rest pay for parking, so 15,000-10,000 = 5,000 people pay for parking. At $25 each, this amounts to 25*5,000 = 125,000 dollars earned through this option.
Overall, the city earns a total of 50,000+125,000 = 175,000 dollars
Side note: this assumes that the remaining 5,000 people all take separate cars and no single car has more than one person. This is very unrealistic as there are likely to be families or carpools of some kind. So in reality, the answer shown above is an upper estimate of the total revenue.

A large university accepts 40% of the students who apply. Of the students the university accepts, 35% actually enroll. If 30000 students apply, how many actually enroll?
Answer:
the students enroll is 4,200
Step-by-step explanation:
The computation of the students enroll is shown below:
= Number of students × applied percentage × enrolled percentage
= 30,000 × 40% × 35%
= 4,200
hence, the students enroll is 4,200
together teammates Bella and Ricky got 2,686 base hits last season Bella had 278 more hits than Ricky how many hits did each player have
Answer:
Bella: 1482
Ricky: 1204
Step-by-step explanation:
Form an equation:
let x be the number of hits ricky has
then bella would have x + 278 hits
So the equation would be:
[tex]x + x + 278 = 2686[/tex]
now, solve
combine like terms
[tex]2x+278=2686[/tex]
subtract 278 from both sides
[tex]2x = 2408[/tex]
divide both sides by 2
[tex]x=1204[/tex]
since bella has x + 278, she has 1204 + 278 = 1482 hits
Factor this equation using the Zero product property , What are the x-intercepts?: f(x)=2x^2+5x-3
Answer:

Step-by-step explanation:
[tex]f(x)=2x^2+5x-3[/tex]

Zero Product Property
X-Intercepts
____________________
To find the x intercepts, we need to first factor our given polynomial. The quickest trick I use to factor is to find two numbers that multiply to c (in this case -3) and the same two numbers that add to b (in this case 5).
The two numbers would be -1 and 3, but along with 2x to help out.
Therefore the binomial for this factor is :
[tex](2x-1)(x+3)[/tex]
Now to solve the x-intercepts, we separate the binomials into an algebraic expressions :
2x - 1 = 0
x + 3 = 0
Isolate for x in both of them :
2x - 1 = 0
Add 1 to both sides :
2x = 1
Divide both sides by 2 :
x = 1/2
x + 3 = 0
Subtract 3 from both sides :
x = -3
