Answer:
Step-by-step explanation:
You can start by rewriting the equation so that the right side equals zero. Add

and

to both sides.

You can now use the quadratic equation (below), where

and

, to find solutions. Plug in these values for

and

into the equation and simplify.




The final answer is the combination of both solutions.

Or approximately...

The image of (0,6) after a reflection over the y-axis is (0, 6)
<h3>How to determine the image of (0,6) after a reflection over the y-axis?</h3>
The point is given as:
(0, 6)
The rule of reflection is given as:
Reflection over the y-axis
The rule of reflection over the y-axis is represented as:
(x, y) = (-x, y)
So, we have:
(0, 6) = (-0, 6)
Evaluate the expression
(0, 6) = (0, 6)
Hence, the image of (0,6) after a reflection over the y-axis is (0, 6)

The probability that Gina randomly selected two red marbles is 1/19
<u>Explanation:</u>
Total number of marbles = 7 + 5 + 8
= 20
The probability of getting two red marbles in the fraction form is given as:
P(first red marble) = number of red marbles / total number of marbles
P(first red marble) = 
P(second red marble) = number of red marbles after 1 white marble is removed / total number of marbles after 1 red marble is removed.
P(first red marble) = 
P(two red marbles) = P(first) X P(second)
= 
= 
Therefore, the probability that Gina randomly selected two red marbles is 1/19
