Answer:
B and C
Step-by-step explanation:
Uses my calculator and put the table in for worker be and thats how i found the slope was 12.5 . then i used to to figure out that when the hour got to 10 worker B starts making more money.
Similarities: same atomic number
Differences: they have a different number of neutrons
(2x + 3y = 12) x (-2)
(4x - 3y = 6) x 1
-4x - 6y = -24
4x - 3y = 6
You can cancel out the x values by adding the two equations together.
(-4x + 4x) + (-6y - 3y) = (-24 + 6)
-9y = -18
y = 2
Solve for x now...
4x - 3(2) = 6
4x - 6 = 6
4x = 12
x = 3
Check... (x = 3, y = 2)
2(3) + 3(2) = 12
6 + 6 = 12
12 = 12 <- this works!
4(3) - 3(2) = 6
12 - 6 = 6
6 = 6 <- this works!
