Answers

Using it's concept, it is found that the vertical asymptote of the function [tex]f(x) = \frac{3}{x+5}[/tex] is of x = -5.

What are the vertical asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.

In this problem, the function is fraction given by:

[tex]f(x) = \frac{3}{x + 5}[/tex]

At the denominator, we have that:

x + 5 = 0 -> x = -5

What is coordinate geometry?

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

We have the coordinates of the point A = (0, 0) and D is  (0, b).By applying the formula to find the distance between A and D.

AD = [tex]\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b[/tex].

Answer:

x:     y :

Step-by-step explanation:

y = 10x + 1

(Table)

x:      y:

-5  |

-1   |

0   |

1    |

Lets begin plugging in our (x) into the function(x = -5)

y = -10(-5) + 1

y = 50 + 1     (if you multiply a negative by a negative it will be positive)

y = 51

(x = -1)

y = -10(-1) + 1

y = 10 + 1

y = 11

(x = 0)

y = -10(0) + 1

y = 0 + 1

y = 1

(x = 1)

y = -10(1) + 1

y = 10 + 1

y = 11

Got this right on the segment exam. Good luck, my FLVS fellows!

geometry please help!

Answers

Answer:

x = 3

Step-by-step explanation:

Angle S and Angle T are consecutive interior angles. Therefore, we know that T + S = 180°.

First, we need to solve for T, and since angles S and T are consecutive interior angles, we know that T + S = 180°. If we reorganize the equation to include the things we know (S = 105°), then we get 180° - 105° = 75°. So T is 75°.

Now, we use T = 75° and the information given to us in the picture to set up an equation. 75 = 24x + 3. Now, we can find x by isolating it. Do this by:

1) Subtracting 3 from both sides to give you 72 = 24x. We do this to get rid of the 3 from the "x side", but we must also do it to the other to keep the equation true. This moves the 3 from the "x side" to the other since we're trying to isolate x.

2) Divide 24 by both sides to get 3 = x. We use the same logic as we did for 3, except this time we divide since that's the opposite of multiplying.

In conclusion, x = 3.

#24. you and your friends go to the county fair the cost to get in is $8 and the tickets per game to my cost $0.25 each. Write an equation to create a table of reasonable values and identify the domain and range for the scenario.​

Answers

The equation of the scenario is y = 8 + 0.25x and the domain is x ≥ 0 and the range is y ≥ 8

How to determine the equation?

The given parameters are:

Entrance fee = $8Rate = $0.25 per person

Let the total cost be y, and the number of people be x.

The equation would be:

y = Entrance + Rate * x

This gives

y = 8 + 0.25x

Hence, the equation of the scenario is y = 8 + 0.25x

The table of values

Set x = 0 to 5, and calculate the function values

y = 8 + 0.25 * 0 = 8

y = 8 + 0.25 * 1 = 8.25

y = 8 + 0.25 * 2 = 8.50

y = 8 + 0.25 * 3 = 8.75

y = 8 + 0.25 * 4 = 9.00

y = 8 + 0.25 * 5 = 9.25

So, the table of values is:

x    y

0    8

1      8.25

2     8.50

3     8.75

4     9.00

5    9.25

The domain and the range

The domain is the set of people that can get in (i.e. at least 0), while the range is the total amount (i.e. at least the entrance fee)

Hence, the domain is x ≥ 0 and the range is y ≥ 8
