Answer:
Please, see attached picture
Step-by-step explanation:
We can easily solve this question by using a graphing calculator or any plotting tool.
The equation is
y = 3 ^ √(x)
Which can also be represented as
y = 3 ^(x^(1/2))
Let the unknown number be
.
Then the opposite of this unknown number will be
.
It is given to us in the question that when this unknown number,
is increased by 9, or in other words when 9 is added to this unknown number,
, then this becomes 5 times it's opposite, which is
.
Thus, from the given condition in the question, the equation we get is as:

We will solve this by isolating
as:



Thus the required number is -1.5
Answer: 7/3
Step-by-step explanation: let the original real number be x. After moving the decimal point of this real number two digits to the right, the number becomes 100x. The positive difference between the two numbers is 100x - x = 99x. Dividing the difference by 11, we have 99x/11 = 9x, which we are told is 21, so we have the equation 9x = 21/9, which equals 7/3. Thus, the original real number is 7/3.
First, you can factor them into (x-8)(x+9)=0 then set x-8=0 and x+9=0, in which you get X = 8 or X = -9
If 36x^3a+45xa^2=9a() then 9a is a factor the other factor, (), is the left side divided by 9a
(36x^3a+45xa^2)/(9a)
4x^3+5xa
So the () term is (4x^3+5xa)
