If y = 4x – 1, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

Helga [31]

Hello!

To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.

y=4(0)-1
y=-1

So here, an ordered pair could be (0,-1)

We can try this again for different x-values.

y=4(1)-1
y=3

This gives us the ordered pair (1,3)

y=4(100)-1
y=399

This would give us the ordered pair (100,399)

I hope this helps!

The slope of the graphed line is. Which formulas represent the line that is graphed? Check all that apply. Y – 1 = (x – 2) y – 2

IceJOKER [234]

The formula or equation which represent the graphed line with point (1,2) (4,4) and slope 2/3 are,

$(y-2)=\dfrac{2}{3}(x-1)\\$

$(y-4)=\dfrac{2}{3}(x-4)\\$

<h3>What is the equation of a graphed line?</h3>

The equation of a graphed line is a way to represent the line which lies on a point on the xy-coordinated with and informed about the steepness and the direction of the line.

The standard form of the equation of a graphed line can be given as,

$y=mx+c$

Here, (<em>c</em>) is the y intercept of the line and (<em>m</em>) is the slope of the line.

Here, the slope of the graphed line is 2/3. The graph for this problem is attached below.

The two point in the graph below are (1,2) and (4,4). Then the equation of the line, for this two points with slope 2/3 can be given as,

$(y-2)=\dfrac{2}{3}(x-1)\\$

Using the points (4,4), we get,

$(y-4)=\dfrac{2}{3}(x-4)\\$

Thus, the formula or equation which represent the graphed line with point (1,2) (4,4) and slope 2/3 are,

$(y-2)=\dfrac{2}{3}(x-1)\\$

$(y-4)=\dfrac{2}{3}(x-4)\\$

What is the volume of a sphere with a radius of 1/2

krok68 [10]

Step-by-step explanation:

$Volume = \frac{4}{3} \pi r^3$

$V = \frac{4}{3} \pi (\frac{1}{2} )^3$

$V=\frac{4}{3}\pi (\frac{1}{8})$

$V= 0.5233..$

So, the volume of the sphere would be 0.523.

Plz find x and y WILL GIVE BRAINLIEST!!!!!!

Elina [12.6K]

Answer:

x=-2 and y=2

Step-by-step explanation:

Do simultaneous equations

-8x + 4y = 24 <em>(multiply everything in the equation by -7)</em>

-7x + 7y = 28 <em>(multiply everything in the equation by 8)</em>

56x - 28y = -168

-56x + 56y = 224

<em>(add equations, ie add 'x' parts, 'y' parts, and numerical parts)</em>

<em> </em>28y = 56

∴y = 2

-8x + 4y = 24

-8x + 4(2) = 24

-8x = 16

∴x=-2

Lemme know if you have questions :D
