Answer:

Domain : { -3, 0, 3}

Range : { 1 , 1 , 1 }

Function : These set of ordered pairs are functions as every x-value has only one y-value associated with it.

The quotient of a number and 3 less than twice the number

sweet-ann [11.9K]

"The quotient of a number and 3 less than twice the number" would translate to the expression x/(2x-3)

Basically we have x up top the fraction and 2x-3 in the bottom denominator of the fraction. The slash / means divide

What is the equation of the line that goes through (-5,0) and (-4,4)

Tasya [4]

Answer:

$y=4x+20$

Step-by-step explanation:

To write an equation, use the slope-intercept equation:

$y=mx+b$

M is the slope and b is the y-intercept.

First, find the slope by using the slope formula for when you have two points:

$\frac{y(2)-y(1)}{x(2)-x(1)}=\frac{rise}{run}$

Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:

$(-5,0)(-4,4)\\(-5(x1),0(y1))\\(-4(x2),4(y2))\\\\\frac{4-0}{-4-(-5)}$

Simplify parentheses (two negatives make a positive) and simplify:

$\frac{4-0}{-4+5}\\\\\frac{4}{1}=4$

The slope, m, is 4. Insert this information into the equation:

$y=4x+b$

Now, take one of the points and insert into the slope-intercept formula:

$(-5,0)\\(-5(x),0(y))\\\\0=4(-5)+b$

Solve for b, the y-intercept. Simplify multiplication:

$0=-20+b$

Add 20 to both sides and simplify:

$0+20=-20+20+b\\20=b\\b=20$

The y-intercept, b, is 20. Insert this value into the equation:

$y=4x+20$

Done.

The volume of a solid cylinder is 1584 cubic cm and its height is 14 cm. The radius is

enyata [817]

Answer: 6 cm

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder (V): π x radius ² x height

Replacing with the values given and solving for v (Volume)

1584 = π x r ² x 14

Solving for r:

1584 / (π x 14) = r²

36.01 = r²

√36.01 = r

6 cm = r

In conclusion, the radius of the cylinder is 6 centimeters.

Feel free to ask for more if needed or if you did not understand something.

Solve these plz and give a explanation <br>

Answer:

$\large{ \tt{☄ \: EXPLANATION}} :$

✎ Firstly , Remember these things :

To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : $12\% = \frac{12}{100} = \boxed{ 0.12}$

$\large{ \tt{☥ \: LET'S \: SOLVE}} :$

$\large{1. \: \: 52\% \: \text{of} \: 210 = \frac{52}{100} \times 210 = 0.52 \times 210 = \boxed{109.2} }$

$\large{ 2. \: \: 35\% \: \text{of} \: 500 = \frac{35}{100} \times 500 = 0.35 \times 500 = \boxed{175} }$

$\large{3. \: 28\% \: \text{of} \: 866 = \frac{28}{100} \times 866 = 0.28 \times 366 = \boxed{102.48} }$

$\large{ \tt{✺ \: REPEAT \: DAILY} }:$

I will remain focused on my goals. Even if I have a moment of difficulty , I will not give up. I know Success comes with consistency. I know that I will make it. Things will get better. No problem or challenge will stop me. Everything I deserve is coming my way.
