Last week Tina are in $2.50 less than twice what earned how much did Tina earn last week if add earn $6.50?

Tina earned $11.5

Step-by-step explanation:

From the question, we are told that Tiana earns 2.50 less than twice what is earned by Add

let us have x as what is earned by Add

Thus, we have what is earned as 2x-2.5

Now Add, earned 6.50, so we want to know what Tina earned

That would be;

2(6.5) - 2.5

= 13-2.5

= 10.5

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 : )
