Answer:
9×2
Step-by-step explanation:
(-3x)2=-3x×-3x=9×2
I'm pretty sure it's 7 and 1/7
8 percent (C)
To find 1% you divide 4.50 by 100, which is 0.045.
Then you have to find what is added on.
4.86-4.50 is .36
Now you divide .36 by 0.045. An easier way to do this is 360 divided by 45. This equals 8.

To find the slope of the above equation, it is easiest to put it into slope-intercept form, y=mx + b, where the variable m represents the slope. To do this, we must isolate the variable y on the left side of the equation by using the reverse order of operations. First, we should subtract 3x from both sides of the equation.
3x + 6y = 9
6y = -3x + 9
Next, we should divide both sides of the equation by 6 to undo the coefficent of 6 on the variable y.
y = -1/2x + 3/2
Therefore, the slope of the line is -1/2 (the coefficient of the variable x in slope-intercept form).
Hope this helps!
