I^2 is negative 1, but I see you have a negative sign there. So it is -(-1), which is 1.
You add the second equation to the first which eliminates x and leaves you with 2y=18 so you divide 18 by 2 which is 9 so y=9 now you fill in one question for y so do x+4(9)=9 you get x+36=9 now subtract 36 from 9 and you get -27 so x=-27 and y=9
Answer: STOP
Step-by-step explanation:
Answer: 42
Step-by-step explanation:
First you have to subtract 450 from 6750 to get 6300
Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450
Third you have to do 6300 / 42 to get 150 so if you times 150x 42 equals 6300.
Answer:
x = (h-12y-2)/4
Step-by-step explanation:
Here, we want to make x the subject of the formula
We have this as:
h = 4x + 12y + 2
4x = h-12y-2
x = (h-12y-2)/4
