Answer:
The correct option is (a) i.e.
h(-4) = -2
Step-by-step explanation:
The mathematical expression is given as :
......(1)
Where
h(x) is dependent on x
We need to find the value of h(x) at x = -4 . Putting the value of x in equation (1) we get :
h(-4) = -2
The value of h(-4) is -2. So, the correct option is (a). Hence, this is the required solution.

1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula to find the distance from point
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
