First, remove the parentheses
-7+2x+7=-7
Cancel the equal terms.
2x+7=0
Subtract 7
2x= -7
Divide both sides by 2
Final answer is:
X= -3.5
1/2x-2/5=3/5 (BTW I got 2/5 by reducing 4/10)
1/2x=7/5 (BTW I got 7/5 by moving 2/5 to the other side)
Then do 7/5 times 2 and you get 14/5
14/5

Step-by-step explanation:
In order for it to be a function, it has to pass the vertical line test. So draw a line down the middle of the graphs. If it passes once, then it is a function, if it passes more than once it is not.
5pi/6 r^2 = 15pi
R^2 = 18
R= 3sqrt(3)
