Answer:
1. {5,-9}
2.{4}
3.{9/2}
Step-by-step explanation:
The equation 
can be solved as follows:
Then, the solutions of the equation are 
.
Now, if 
, we can solve the equation 
as follows:
So, the unique solution of this last equation is 
The last equation is 
, where 
. To solve this equation we can proceed as follows:
But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.

You've selected wrong one
it's first row, last one
to find the graph is a function or not, it should pass vertical line test.
Draw a vertical line through each graph. It should not cut your graph more than once.
2nd graph from first row is passing vertical line test. so it is a function b

Answer:
The distance around a circle on the other hand is called the circumference (c).
Step-by-step explanation:
A straight line that passes from one side of a circle to the other through the center is called the diameter. The distance around the outside of a circle is called the circumference. All points on the edge of a circle are the same distance to the center.
Probability of coin flip = 1/2, probability of die roll = 4/6
1/2 * 4/6 = 1/3 chance
