Pretty sure it’s..jk do your class
The second one is the correct equation. The constant to the right should be the diameter squared, while the numbers inside the parentheses should be the opposite.
The answer is no y varies 8 x varies 2
I would think it would be b for task 3
First, we write the first equation where the left side contains x and y in the right side. We do as follows:
x = 2y + 6
You, then substitute the equation to the second one.
3(2y + 6) + y = 8
6y + 18 + y = 8
7y = -10
y = -10/7
x = 22/7
