Answer:
(x, y) =(2,-3)
Step-by-step explanation:
4x+3y=-1
3x-9y=33 /:3
4x+3y=-1.....(1)
x-3y=11... (2)
(1)+(2): 5x=10
x-3y=11
x=10/5
x-3y=11
x=2
2-3y=11
x=2
-3y=11-2
x=2
-3y=9
x=2
y=9/(-3)
x=2
y=-3
(x,y)=(2,-3)
Answer:
if that line follows y=mx...then answer is A
But it seems not....when we divided valuse like 60/2=30
75/3=25....
ratio is not the same
Its hard to tell....You must know exact cordinations
I can tell you this
I can say this if y=60 and x=2 and....y=120 and x=4...then it is propotional...but it seems not..
6d+23=14(d-2)
6d+23=14d-28
6d+51=14d
51=8d
51/8= 6.375 or 6 3/8
Hope this helps :)
Answer:
m<5= 46 degrees
m<8= 134 degrees
Step-by-step explanation:
m<5: all you need to do is subtract 134 from 180
m<8: m<2 and m<8 have the same angle
Answer:
y=4, x=8
Step-by-step explanation:
system:
x+y = 12, x=2y
convert to 1 variable, simplify:
2y+y=12
3y=12
y=4
x=2y=4*2=8
