6b < 42 implies b < 42 / 6 = 7, so it is <span>b < 7
</span>4b + 12 > 8 implies 4b > 8 - 12 = -4, 4b > -4, and then b > -4 / 4 = - 1
the answe is <span>b < 7 or b > -1 </span>

The answer is D Because in a tangent
this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5
1)We solve the first equation:
2x-1=5
2x=5+1
2x=6
x=6/2
x=2
2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2
The solutions of this equation /2x-1/=5 will be: x=3 and x=-2
Answer: x=3 and x=-2
