Is there one solution, none, or infinite to the following without graphing?
y=3x+1 and y=3x
None-Parallel Lines
2y+7>11
y>2
| x + 5 | = 9
x = 4 , x = -14
5 (x + 6) = -9x + 2
x = -2
1/3x=10
x = 30
Is there one solution, none, or infinite to the following without graphing?
y=5x+15 and y=5x+15
Infinite-Same Line
5+m+8≥14
m≥1
| x - 6 | = 10
x= 16 , or x = -4
2x + 3 = 19 + x
x = 16
1/3y-1=2/3
y = 5
Is there one solutions, none, or infinite to the following without graphing?
y=2x+8 and y=1x+8
One Solution-Different x amounts
-1-3x>1-4x
x>2
3 | x - 4 | = 21
x = 11, or x = -3
8(1 + 5x) + 5 = 13 + 5x
x = 0
1/10y-1/5=9/10
y=11
Is there one solution, none, or infinite to the following without graphing?
y=8x+10 and y=-8x+10
One Solution-Different x amounts
-3-4x>-3-5x
x>0
6 | x - 3 | = 42
x = 10 or x = -4
2(4x - 5) = 7x + 1
x = 11
1/8y-1/4=7/8
y=9
Is there one solution, none, or infinite to the following without graphing?
y=5x+15 and y=5(x+3)
Infinite-Same Line
-5x≥15
x≤-3
4 | x + 2 | + 3 = 7
x=-1 or x=-3
-3x + 4 = 2x +19
x = -3
1/12y-1/6=11/12
y=13
