Answer:

Answers A and B respectively

Step-by-step explanation:

In the first pic, they are asking you for the value of the function at the points x = -1 and x = 5. Then you are asked to subtract your results. When the value of 'x' is -1, the 'y' value is 3. When the value of 'x' is 5, the 'y' value is -4. Therefore:

\(f(-1)-f(5)=3-(-4)=7\)

Answer A

For the second problem, they are saying that the line connecting points A and B is undefined. This means the slope is undefined along that line. An undefined slope is due to a zero in the denominator. Begin by taking the change in 'y' over the change in 'x' to get:

\(\frac{y_1-1}{x_1+2} =m\)

In order for our slope 'm' to be undefined, set the denominator to zero and see at what 'x' value this occurs at:

\(x_1+2=0\)

\(x_1=-2\)

Then they say that the line connecting points C and D is zero. A zero slope would mean a zero in the numerator. Again, begin by taking the change in 'y' over the change in 'x' to get:

\(\frac{3-y_2}{-5-x_2} =m\)

Set the numerator equal to zero to get:

\(3-y_2=0\)

\(y_2=3\)

Answer:

x = 1

Step-by-step explanation:

1) plug the given f-value into the equation

13 + 14 = 3xf;   f = 9

13 + 14 = 3x(9)

2) isolate x

27 = 3 · 9 · x

27 = 27x

1 = x

x = 1

Answer:

3rd and 4th answer

Step-by-step explanation:

400 × 1.32

or

400 + 400×0.32

why ?

400 × 1.32 = 400 × (1 + 0.32) = 400×1 + 400×0.32 =

= 400 + 400×0.32

in general, this means that the price is 32% higher than the old 100% ($400). so, in total 132% compared to the old price.

therefore the 1.32 factor, which creates 132% out of 100%.

Answer:

0.04

Step-by-step explanation:

Rewrite 3.5 as 3.50, with two decimal places, to match 2.46 and 1.16 in having two decimal places.

Then 3.5 - 2.46 = 1.16 becomes

3.50

-2.46

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer:

y = 50°, x =50°

Step-by-step explanation:

y + 70 + 60 = 180° .......straight line has 180°

y = 180° - 60° -70° =50°

x = y.......here vertical angles are always equal. So,

x = 50°
