The answer is 4 because the bottom and line DE form a right angle
Answer:
Step-by-step explanation:
Let's start by using distributive multiplication:
So:
Grouping like terms:
Now, is equal to:
In this sense:
In order to satisfied the equality:
Hence, from (1), let's solve for a:
And from (2), let's solve for b:
Let's verify the result evaluating the values of a and b into the original equation:
As you can see, the values satisfy the equation, therefore, we can conclude they are correct.

Answer:
(a)
(b)
Solution is not viable
Step-by-step explanation:
(a)
Total number of red ping pong balls
Total number of red ping pong balls
Now, probability of an event
Then, theprobability of randomly choosing a blue ping pong ball is
Given that this probability is
Thus, we have that,
(b)
Solving, the above equation,
This solution is not viable as, number of ping pong ball must be an integer and not a decimal number.
Y = 1/4 x^3 + 2
1/4 x^3 = y - 2
x^3 = 4(y - 2)
x = cube root (4y - 8)
inverse y = cube root (4x - 8)
Its D.
