Find two numbers if their sum is 7.2 and their difference is 2.7.

The two numbers are 4.95 and 2.25.

Let the two numbers be x and y. Given conditions,

...............................(1)

................................(2)

Adding equations (1) and (2), we get

Therefore

x=4.95 .......................(3)

Substituting value of x from (3) in (1), we get

y=2.25 ........................(4)

From (3) and (4), the two numbers are 4.95 and 2.25.

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 : )
