Answer:
one solution
Step-by-step explanation:
2(2b-4)+5=7+2b
4b - 8 + 5 = 7 + 2b
4b -3 = 7 + 2b
4b - 2b = 7 + 3
2b = 10
b = 10/2
b = 5.
it can have only 5 as solution that will be only one solution if we change the value of 5 to other number then the answer will be wrong
Answer:
m= -4
Step-by-step explanation:
use the slope formula m=rise/run y2-y1/x2-x1
Answer:
Step-by-step explanation:
x+y≥-4
consider x+y=-4
when x=0,y=-4
point is (0,-4)
when y=0,x=-4
point is (-4,0)
draw a line through (0,-4) and (-4,0)
put x=0,y=0
0+0≥-4
which is true.
Hence origin lies on the graph.
graph is on and right of the line.
