Answer: Make a chart of x values and corresponding outputs as y-values
Plot the points, draw the curve
Step-by-step explanation: Example of chart
x . y
-1 . 1/9
0 1
1 . 3
2 . 9
3 . 27
Once you do this you will have something similar to graph a or b.
It is difficult to tell from the photo; which graphed curve passes through (2,9) ?
Answer:
<h2>B. x² + 3x - 5</h2>
Step-by-step explanation:

Answer:
that is an obtuse angle and mixed with an aacute, you answer should be 45 or 50 degrees please correct me if im wrong.
Step-by-step explanation:
We know that it must equal 9, and that we do x•x-x+6 and find the square root
Answer:
Multiply the top equation by -3 and the bottom equation by 2
Step-by-step explanation:
Given <u>system of equations</u>:

To solve the given system of equations by addition, make one of the variables in both equations <u>sum to zero</u>. To do this, the chosen variable must have the <u>same coefficient</u>, but it should be <u>negative</u> in one equation and <u>positive</u> in the other, so that when the two equations are added together, the variable is <u>eliminated</u>.
<u>To eliminate the </u><u>variable y</u>:
Multiply the top equation by -3 to make the coefficient of the y variable 6:

Multiply the bottom equation by 2 to make the coefficient of the y variable -6:

Add the two equations together to <u>eliminate y</u>:

<u>Solve</u> for x:


<u>Substitute</u> the found value of x into one of the equations and <u>solve for y</u>:
