x+y-z+w = 10--------(1)
x+3y-4z+5w=26------(2)
x+4y-7z+7w = 37-------(3)
x+2y-3z+6w = 22--------(4)
Subtract equation (1) from (2)
x+3y-4z+5w - (x+y-z+w) = 26 - 10
2y + -3z - 4w = 16-----------------------------(5)
Subtract equation (1) from (3)
Let
A = (0,0)
B = (0,6)
C = (8,0)
Let point M be the midpoint of segment AB. In this case M = (0,3) since we just average the x and y coordinates of A and B. Similarly, N = (4,0) is the midpoint of segment AC.
Because AB is completely vertical, and because AC is completely horizontal, this means that the center is (4,3). Notice that the x coordinate is drawn from point N and the y coordinate is drawn from point M.
Final Answer: (4,3)See the image attachment for a visual.
4w is the answer that i believe is correct
Answer:
-1 5/9
Step-by-step explanation:
so first, simplify the signs so they don’t confuse you,
-5/6 - 17/18 + 2/9 (Since there are two negatives near the end, and their tecxhnically being mulitplied, -2/9*-1 (I added 1 for place holder) and when you multiply a negatives by a negative, you get a positive.
So find the lcm of the denominators which is 18 in this case
-15/18 - 17/18 + 4/18
Now solve the problem from left to right
you’ll get -1 5/9 if you simplified
