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:
$ 60
Step-by-step explanation:
p(x) = 7x + 25
f(1) = 2.1² + 3 = 5
p(f(1)) = p(5) = 7 . 5 + 25 = 35 + 25 = 60
so he get $ 60 for 5 hours work with tips
The college student spends 45 dollars on laundry.
To find this you have to divide 495, by 11. This is because the question states "the college student spends 10 times more on pizza than laundry", which means the cost of the laundry (l) is added to the cost of pizza (10p). Dividing 495 by 11, you get 45.
As I stated earlier, the cost of laundry is added to the cost of pizza. 45 * 10 is 450. 450 + 45 = 495. Thus making 45 the answer.
I hope this helps!
