5/1x or simply 5x is the slope
2/3x +12/3 =7
2/3x + 4 =7
2/3x=7-4
2/3x=3
x=3*3/2
x=3
10y + 70= 12y
12y-10y=70
2y=70
y=70/2=35
Answer:
D. y<u>></u><u> </u>1
The shaded area on the graph is y>1 but since the line is solid it is also equal to 1.
3z - 7 = 14 |add 7 to both sides
3z = 21 |divide both sides by 3
z = 7
