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:
360 for his expenses. Now if he extends his tour for 4 days then total days of the tour turns out to be x+4 days. Answer is 20 because -24 is not possible as days cannot be negative. So option (d) is the answer.

Let f(x) represents function that tells us Derek's earning depending on square feet of lawn mowed which is x.
First we construct function:
f(x) = x/1000 * 1 + 30
x/1000 is a number that tells us the number of mowed units. for x = 1000 square feet he earns 1 dollar that is why we have to divide x by 1000.
if he earned 204 first week that means that x =:
204 = x/1000 + 30
x/1000 = 174
x = 174 000
if we check for each week that he worked we will see that square footage of the lawns he mowed match forth (last) option.
Answer is D.

The bank which will charge a customer more in fees if she writes 18 checks per month, and by how much is Bank A by $0.30
<h3>How to write and solve equation?</h3>
let
Bank A = 2.50 + 0.15x
= 2.50 + 0.15(18)
= 2.50 + 2.7
= $5.20
Bank B = 4 + 0.05x
= 4 + 0.05(18)
= 4 + 0.9
= $4.9
Difference in charges = $5.20 - $4.90
= $0.30
