Answer:
(x,y)=(3/2, -1/2)
Step-by-step explanation:
2x+4y=1 /*3
3x-5y=7 /*(-2)
6x+12y=3
-6x+10y=-14
...........................
/ 22y=-11
y= -11/22
y= -1/2
2x+4*(-1/2)=1
2x-2=1
+2 +2
2x=3
x=3/2
so the solutionis (x,y)=(3/2, -1/2)
Answer:
176
Step-by-step explanation:
91/9.10=0.10
17.60/0.10=176
That is a perfectly horizontal line, and perfectly horizontal lines are "y=" lines. Which y point does it go through? It goes through at y = 2 and x = 0, so the equation for the line is y = 2, choice A from above.
The area is what is given. Find the base and height and multiply that. Since, you done that, you simplify if any fraction is there. Then, you have an answer!
