When a number is increased by 9 it is five times its opposite. find the number.

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: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
