Answer:
5x-2y=-20
Step-by-step explanation:
y-y1=m(x-x1)
y-5=5/2(x-(-2))
y-5=5/2(x+2)
y-5=5/2x+10/2
y-5=5/2x+5
y=5/2x+5+5
y=5/2x+10
y-5/2x=10
-5/2x+y=10
2(-5/2x+y)=2(10)
-10/2x+2y=20
-5x+2y=20
5x-2y=-20

Step-by-step explanation:
1.
Dependent variable: a
Independent variable: c

x = 9
x = 15
x = 4
x = 36 (assuming that says x = 12 * 3)
In the graph you can see the point are crossing Y -1 and x= 2,
x-y=xy
2-1=1
Y=1
8/ 712 is 72
First see if 8 can go into 71
8 goes into 71 8 times then subtract 71 and 64 since 8*8 is 64
Finally you will get the solution 72 so find how many time 8 can go into 72 and that will be 9.
