Is (2, 2) a solution of the system y = x and x + 2y = 6?
2 answers:
Answer:
Yes.
Step-by-step explanation:
2=2, yes
2+2(2)=2+4=6, yes
Answer:
yes
Step-by-step explanation:
Substitute x = 2 and y = 2 into both equations and if both are true then (2, 2) is a solution of the system.
y = x, that is
2 = 2 ← True
x + 2y = 6, that is
2 + 2(2) = 2 + 4 = 6 ← True
Thus (2, 2) is a solution of the system

I think I got this wrong I'm sorry if I couldn't help
He has to drive around the track about 1.5 times.
We first find the circumference:
C = 2πr = 2(3.14)(1.6) = 10.048
We now divide 15 by this:
15/10.048 ≈ 1.5

It could be any thing as long it is reasonable . I would say 250 because 500-250.
