Answer:..............................
Step-by-step explanation:
I think the answer is C ( 11 )
The answer to an absolute equation problem being equal to a negative is no solution.
The reason for this is because an absolute value symbol makes everything inside positive. Therefore, there is no way it could equal -5/2.
Note that the from
![-\infty](https://tex.z-dn.net/?f=-%5Cinfty)
to 0, that is the left part, the function is the line y=1.
Similarly, from 0 (not included) to
![\infty](https://tex.z-dn.net/?f=%5Cinfty)
, the function is y=-1.
Thus the function is given by the rule:
y=1, for x≤0,
y=-1, for x>0.
Remark: a horizontal line at height c, from the x-axis, is the graph of the function y=c.
Step-by-step explanation:
5(2x+4)=15
10x+20=15
10x=15-20
