Rudiy273 years ago
3 0

Answer:

y = -2/3 + 3

Step-by-step explanation:

y2 - y1 / x2 - x1

-3 - 1 / 9 - 3

-4 / 6

-2/3

y = -2/3x + b

1 = -2/3(3) + b

1 = -2 + b

3 = b

y = -2/3 + 3

Which of these tables represents a function
Sauron [17]

The table that represents a function is:

  • C. Y

<h3>What is a Function?</h3>

A function is an expression that represents the relationship between two variables. The variables in this case are the dependent and independent variables.

To identify a function, you need to note that no variable of x should be equal to y.

The formular is represented this way: y = f(x). The table that satisfies this condition is the Y table.

How many solutions does this system have? 12 x - 4 y = - 8. y = 3 x + 2.
Contact [7]

Answer:

infinite

Step-by-step explanation:

if you graph the  equation it would overlap.

overlap = infinite

parallel = no solution

intersect = one solution

How do you graph 24x−6y=18
nikklg [1K]

Answer:

You will graph a function with the equation being y = 4x - 3, to plot this function read step by step explanation.

Step-by-step explanation:

First we have to find the equation of the line so we do....

24x - 6y = 18

24x = 18 + 6y

6y = 24x - 18

y = 4x - 3

Now that we know the equation we just have to find two point by using this equation and connect them between each other in order to graph the function represented by this equation. For example

For x = 0

y = 4x - 3

y = -3

So we know that there is a point (0, - 3)

For x = 1

y = 4x - 3

y = 4 - 3

y = 1

So we know that there is a a point  (1, 1)

Connect the two point and you will get the function graph

WILL GIVE BRAINLIEST! Match the equations that are the same
wolverine [178]

Answer:

1. 1/x = 8

Answer = 8x-1

2. 8x+1=3

Answer ; x=1/4

3. 7= 14/X

Answer ; x = 2

4.1/2x^2 = 2

Answer ;x=2

Step-by-step explanation:

\frac{1}{x} =8 \\8x = 1\\\\\\8x+1=3\\Collect -like- terms \\8x =3-1\\8x = 2\\Divide -both -sides- by ;8\\\frac{8x}{8} =\frac{2}{8} \\x = 1/4\\\\\\7= \frac{14}{x} \\Cross -multiply\\7x =14\\Divide-both-sides-by-7\\x = 2\\\\\\\frac{1}{2} x^{2} =2\\\frac{x^{2} }{2} =2\\Cross-multiply\\x^{2} =4\\Squre-root -both-sides\\\sqrt{x^2}=\sqrt{4}  \\x = 2\\
