Answer 1

Explanation:

We're given one equation, we have to find the other equation and solve each for 200, and whichever has the lower x is the winner

for Jayden we are given

`(0, 48), (1, 56), (2, 64), (3, 72), (4, 80)`

This looks to be a line. The y values are each separated by a common difference

We can use two points to describe the line

`m = (y_2-y_1)/(x_2-x_1) = (80-48)/(4-0) = (32)/(4) = 8\\ K = 8m + b\\48 = 8(0) + b\\b = 48\\so\\K = 8m + 48`

Now we can set both
`K = 8m + 48` and
`K = m^2 + 10` equal to 200

`200 = 8m + 48\\152 = 8m \\m = (152)/(8) = 19`

`200 = m^2 + 10\\m^2 = 190\\m = √(190) = 13.784`
