Answer:

There is no table in your question.

Step-by-step explanation:

Describe how to write an equation from a table of values using a graph. No there is not a graph that is all I was given for the question.

Answers

Answer:

Look that the coordinates and trace those points to a corresponding number on the x or y axis. Then write the first number in the coordinate in the x value and the second number for the y value, repeat the process for the rest of the points.

An example is (-3,2), if you see the point (-3,2) on your graph, plug in -3 for the x value and 2 for the y value (don't include this example into your response - it was just for you to see what I mean)

Answer:

just look at the step by step

Step-by-step explanation:

To Write an equation for a table using a graph each point on the coordinate plane. Draw a line through the plotted points. Then,find the y intercept(where the line crosses the Y-axis.) Figure out from the graph what the rise and the run are and calculate the slope.Then,put the equation in y=mx+ b format.

Answers

Answer: 9

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle.

[tex]a^2+b^2=c^2[/tex]

[tex](\sqrt{63}) ^2+x^2=12^2\\63+x^2=144\\x^2=81\\x=9[/tex]

X=9

A squared + b squared = c squared

C is the hypotenuse (the side opposite of the right angle)

X*2 + square root of 63 squared = 12*2
Squaring 63 would cancel out with the square root. You are left with x*2 + 63 = 144. 144-63= 81. X*2=81 ; square root both sides. You are now left with x=9
