Answer:
x = 4.25
Step-by-step explanation:
First, alter the equation until both exponents have the same base. We know that 9^3 is 27. Therefore, we can change 27^(x-3) into 9^3(x-3).
Now, the equation can be written as 9^(8-x) = 9^(3x-9)
Now that the bases are the same, we can cancel them out and just solve for the exponents. This will look like:
8-x = 3x-9.
8 = 4x - 9
17 = 4x
x = 4.25
Answer:
-4
Step-by-step explanation:
-√16
-4
These are all linear equations, which means their graph is a straight line.
So, you need only two points in your chart to draw them accurately.
If you choose them sufficiently far apart, your graph is the most accurate.
For y=2x, lets use -3 and +3:
x y
-3 -6
3 6
Draw dots on the graph paper, then a straight line through them. You can add additional points to the table, they should all fall on the line.
