Answer:As you can see, this line is vertical! It goes directly up. We know that because the equation says that X is equal to -3. It is telling us that no matter what the Y value is, X will be -3.

Step-by-step explanation:

The equation to find slope is to take two points

(A,B) and (C,D) and to do the following equation: D−B

                                                                               ______

                                                                                  C−A

So, let's take two points. Let's say that Y is equal to 3 and 2. In that case, since X is always -3, our points would be (−3,2) and (−3,3).

Now, let's substitute into our formula.

3−2                       1         1

------ =                  ----- =   ---

3 (−3) (subtract)  -3 + 3   0

As you can see, the final slope is 1/0

. If you put that into your calculator, it will come out as undefined, because any number divided by zero is undefined. And so your slope for any vertical line is undefined.

The average rate of change of the function at the interval x = 5 to x = 9 is 1.25

The interval is given as

x = 5 to x = 9

From the question (see attachment), we have the following parameters that can be used in our computation:

x = 5 and y = 15

x = 9 and y = 20

This means that

f(5) = 15 and f(9) = 20

The average rate of change is then calculated as

Average rate of change = [f(9) - f(5)]/[9 - 5]

Substitute the known values in the above equation, so, we have the following representation

Average rate of change = [20 - 15]/[9 - 5]

Evaluate

Average rate of change = 1.25

What is PPG Statistics?

First, consider the PPG of the current leader of the season from among the two basketball players.

The total number of points obtained by the current leader is equal to 2112.

The total number of games played by the current leader is equal to 77.

The points per game obtained by the current leader can be calculated as follows,

PPG = Total Points Obtained / Total Number of Games

[tex]\implies PPG=\frac{2112}{77}\\\implies PPG=27.42[/tex]

Now, consider the PPG of the second place player for the season.

The total number of points obtained by the second place player is equal to 2020.

The total number of games played by the second place player is equal to 74.

The points per game obtained by the second place player can be calculated as follows,

PPG = Total Points Obtained / Total Number of Games

[tex]\implies PPG=\frac{2020}{74}\\\implies PPG=27.29[/tex]

Subtracting the points per game of both players, we get

[tex]27.42-27.29=0.13[/tex]

Hence, the leading team has scored 0.13 points per game (PPG) for the season compared to the second place player.

The domain of a function is defined by the set of the values of independent variables and the ranges are the set of values of dependent variables.

The domains act as an input of function where ranges act as an output.

We select domain randomly as domain are the set of independent variables. But how will be the ranges must depend on the function given us.

we are given 2 function u(x) = -2x²+3 and v(x)

for the 1st function the set of domain and ranges are different, but the domain and ranges have the same values for the 2nd function.

we select domain x= {-3, -2, -1, 0, 1, 2, 3}

the ranges for u(x) ={ -15, -5, 1, 3, 1, -5 , -15}

because, u(-3) = -2(-3)²+3 = -15

                u(-2) = -2(-2)²+3 =-5

               u(0) = 3

similarly, for the same set of x value, v(-3) = -3

Answer:

1.  y=2x−5

2.  y=-x-4

3. y=-1/2x+1

Step-by-step explanation:

First Question:

We are given (3, 1) and (1, -3)

The slope is the difference of y-values over x-values. From this we get:

(1−−3)/(3−1)=4/2=2

Now, we want to find the y-intercept. To do this, we plug our slope and one of our points into the slope intercept equation: y=mx+b

Plugging in (3, 1) gives us         1=3∗2+b    ⇒    b=1−6 = −5

We have our slope and y-intercept now, so the equation is y=2x−5.

Second Question:

We are given (-4, 0) and (1, -5)

The slope is

(-5-0)/(1--4)=-5/5=-1

Now, we want to find the y-intercept. To do this, we plug our slope and one of our points into the slope intercept equation: y=mx+b

Plugging in (-4, 0) gives us         0 = -1∗-4+b    ⇒    b = -4

We have our slope and y-intercept now, so the equation is y=-x-4.

Third Question:

We are given (-6, 4) and (-2, 2)

The slope is

(4-2)/(-6--2)=2/48=-1/2

Now, we want to find the y-intercept. To do this, we plug our slope and one of our points into the slope intercept equation: y=mx+b

Plugging in (-2, 2) gives us         2 = -1/2∗-2+b    ⇒    b = 2-1 = 1

We have our slope and y-intercept now, so the equation is y=-1/2x+1

Answer:

f(x) = -2x +7

Step-by-step explanation:

The 2-point form of the equation for a line is suitable for this. For points (x1, y1) and (x2, y2), the equation is ...

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

For the given points (0, 7) and (3, 1), the equation is ...

y = (1 -7)/(3 -0)(x -0) +7

y = -6/3x +7 . . . . . . . . simplify.

We can use f(x) for y to get ...

f(x) = -2x +7

The expression -16x^(-3/2) represents a term that has a coefficient of -16 and a variable x raised to the power of -3/2.

Generally, The expression -16x^(-3/2) represents a term that consists of a coefficient of -16 and the variable x raised to the power of -3/2.

In general, the exponentiation operator (^) represents the idea of raising a number (called the base) to a certain power (called the exponent). For example, x^2 means "x raised to the power of 2" and can be calculated as x * x = x^2.

Similarly, x^3 means "x raised to the power of 3" and can be calculated as x * x * x = x^3.

The exponent -3/2 means that the base (in this case, x) is raised to the power of -3/2. This can be simplified as follows:

x^(-3/2) = 1 / x^(3/2) = 1 / (x^(3/2))

The expression -16x^(-3/2) can then be simplified as follows:

-16x^(-3/2) = -16 * 1 / x^(3/2) = -16 / x^(3/2)

The distance the pear will be in the air if his Dad sees him and catches if at 6 feet above the ground is 19/30 meters.

The term distance can be defined as a numerical qualitative measurement of how far apart  points are from each other.

Distance is defined by the formula

d=v*t

The given parameters are:

v=30

s=6

height=25

Applying these parameters into the formula

d=30*t

d=30t

If the Dad stands 6 feet above the ground, we have

1 hot dog cost is $1.20 .

What is costs?

A cost is the value of money that has been expended to produce something or provide a service and is therefore no longer available for use in production, research, retail, and accounting. In the case of an acquisition cost, the money spent on the acquisition is considered the cost.

Let's say that each drink costs $x and each hot dog costs $y.

Using the provided information, 3 drinks and 2 hot dogs cost $4.80. In equation form, it reads as follows:

3 x+2 y=4.80

1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:

x+y=2

x=2-y

Using this value of x in first equation, we get:

3(2-y)+2 y=4.80

6-3 y+2 y=4.80

6-y=4.80

y=6-4.80
