Answer:
He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
8 can't be square rooted as an integer. Therefore the answer can only result in a being a decimal, in double brackets or it can be a trick question.
I’m pretty sure the answer is y = x - 2. If not then sorry..
