Answer:

b

Step-by-step explanation:

\frac{ {x}^{2} + 1 }{1}  \times  \frac{1}{x}  =  \frac{ {x}^{2} + 1 }{x}

X cannot equal zero so all real numbers expect zero.

The relation you have shown is not a function.

In order to be a function, a relation's domain must be continuous in that no x-value is not repeated in any of the points. Since the first two points of the relation are (5,1) and (5,3), you can see that they have the same x-value, meaning that this is not a function.

One quick way you could test this is to quickly sketch a graph and use the vertical line test to see if the relation in question is a function. If it cross the vertical line once in all places, it is a function - if it crosses the vertical line more than once in any place, it is not a function.

Answer:

y = -x-3

x-y = -3

x - 2y = 10

Step-by-step explanation:

x − 3y = 6

Slope intercept form is y = mx +b

We need to solve for y

Subtract x from each side

x-x-3y = -x+6

-3y = -x +6

Divide each side by -3

-3y/-3 = -x/-3 +6/-3

y = 1/3 x -2

Standard form is Ax +By = C

y = -x-3

Add x to each side

x-y = -x+x-3

x-y = -3

y = 1/2x -5

We do not like fractions in standard form, so multiply by 2

2y = 2*1/2x -2*5

2y =x-10

Subtract x from each side

-x +2y = x-x-10

-x+2y = -10

We like to have the coefficient on x be positive

Multiply by -1

x - 2y = 10

Answer:

Y=4 X= -6 or (-6,4)

Step-by-step explanation:

Okay so

3x+10y=22

-3x-8y=-14

  1. basically, it's like one big equation. First, subtract 3x from -3x which cancels out and gives us 0
  2. 10y minus 8y gives us 2y.
  3. 22 minus 14 gives us 8

3x+10y=22

<u>-3x-8y=-14</u>

0+2y=8

Now that we have this, we can solve for y. in order to do this, we have to divide both sides by 2.

\frac{2y}{2}  =  \frac{8}{2}

From here we know that y=4 because the 2s cancel out leaving y and 8 divided by 2 is 4.

y= 4

Now we can fill in. You can pick any equation for this but I'm going to chose the first one.

3x+10y=22

we can fill in 4 for y

3x+10(4)=22

3x+40=22

Next we are going to subtract 40 on both sides.

3x+40=22

-40 -40

3x= -18

Next, we're going to divide -18 by 3.

\frac{3x}{3}  =  \frac{  - 18}{3}

The 3s cancel out leaving us x. -18 divided by 3 is -6.

x= -6

Hope this helped!! :)
