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)
Cookies=x
brownies=y
.5x+.75y=100
.5x=100-.75y
x=200-1.5y
400-3y+.75y=100
-2.25y=-300
y=133.333
x=0
Answer:
The equation of this line would be y = -8
Step-by-step explanation:
Since y = 9 is a horizontal line, the parallel line must also be horizontal. All horizontal lines can be written as y = (a number). That number can be found as the y-coordinate in the ordered pair, which is -8.
y = -8
