The amount of hours you worked would be 7.5, you divide 600 by 80.
x^2 + 4x + 3 + 1 = (x + 2)^2
So 1 need to be added.
it has gone up 4 lines and left -2 making it go for a (4,-2)
Answer:
B
Step-by-step explanation:
1) lets use elimination to solve this:
multiply 10x+4y=24 with 3 in order to get "4y" into "12y"
3(10x+4y=24)
30x+12y=72
now subtract both equations to eliminate 'y"
30x+12y=72
-
6x+12y=48
---------------------
24x=24
x=1
now substitute 1 in the above equation:
6(1)+12y=48
6+12y=48
12y=42
y=7/2
3 divided by 5 is 0.6 so 0.65 is bigger
