Answer:
(A) -7
Step-by-step explanation:
The function is continuous if you can draw its graph without lifting your pencil. In this case, that means each of the piecewise function definitions must have the same value at x=3.
x^2 +2 = 6x +k . . . . . must be true at x=3
3^2 +2 = 6(3) +k . . . . substitute 3 for x
9 +2 -18 = k . . . . . . . . subtract 18
k = -7 . . . . . . . simplify
Answer:

Step-by-step explanation:
Answer:
k + 1
v(s) = -------------
S
Step-by-step explanation:
Solve the equation S=k/v(s)+1/v(s) for v(s).
To do this, combine the two terms on the right side, which is easily possible becuse they have the same denominator: v(s):
k + 1
S = ------------
v(s)
Now interchange S and v(s), obtaining:
k + 1
v(s) = -------------
S
Answer:
The equivalent expression is 10x-6.
