Determine the range of the following relation.

Basile [38]

Answer:

The range of the relation is:

Range R = {1, 2, 7}

Therefore, option B is true.

Step-by-step explanation:

Given the relation

Input Output

-4 1

0 7

2 2

7 7

<u>Determining the domain:</u>

We know that the domain of relation consists of all the inputs or x-coordiantes of the ordered pairs.

Thus, the domain of the relation is:

Domain R = {-4, 0, 2, 7}

<u>Determining the range:</u>

We know that the range of relation consists of all the outputs or y-coordiantes of the ordered pairs.

Thus, the range of the relation is:

Range R = {1, 2, 7}

Please note that the duplicated elements in the domain or the range of the function are written only once.

Therefore, option B is true.

A choice got cut off and it’s “-11x+6y=13”. Thank you! And this is a quiz and I have other questions on my account! I need fast

Marrrta [24]

–11x + 6y = –13

Solution:

The points on the line are (5, 7) and (–1, –4).

Here, $x_1=5, y_1=7, x_2=-1, y_2=-4$ \

Slope of the line:

$$m=\frac{y_2-y_1}{x_2-x_1}$

$$m=\frac{-4-7}{-1-5}$

$$m=\frac{-11}{-6}$

$$m=\frac{11}{6}$

Using point-slope formula,

$y-y_1=m(x-x_1)$

$$y-(-4)=\frac{11}{6} (x-(-1))$

$$y+4=\frac{11}{6} x+\frac{11}{6}$

Subtract 4 on both sides of the equation.

$$y=\frac{11}{6} x+\frac{11}{6}-4$

$$y=\frac{11}{6} x+\frac{11}{6}-\frac{24}{6}$

$$y=\frac{11}{6} x-\frac{13}{6}$

Multiply by 6 on both sides of the equation.

$6y=11x-13$

Subtract 11x from both sides of the equation.

–11x + 6y = –13

Hence option A is the correct answer.

What is the measure of AC ? (First Picture)

kondaur [170]

Answer:

Part 1) $arc\ AC=33\°$

Part 2) $arc\ BC=130\°$

Step-by-step explanation:

Part 1) What is the measure of AC ?

we know that

The inscribed angle is half that of the arc it comprises.

$m$

substitute the values and solve for x

$2.5x+4=\frac{1}{2}(7x-2)$

$5x+8=(7x-2)$

$7x-5x=8+2$

$2x=10$

$x=5\°$

Find the measure of arc AC

$arc\ AC=7x-2=7(5)-2=33\°$

Part 2) What is the measure of BC ?

we know that

The inscribed angle is half that of the arc it comprises.

$m$

substitute the values

$65\°=\frac{1}{2}(arc\ BC)$

$2*65\°=(arc\ BC)$

$arc\ BC=130\°$
