Is this question correct ?
Answer:
K = 11
Step-by-step explanation:
3(k - 6) = 15
3k - 18 = 15
3k = 15 + 18
3k = 33
K = 33/3
K = 11
Thus, the value of K is 11
Answer:
Step-by-step explanation:
Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is
f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49
g(- 4) = (- 4)² + 12 = 16 + 12 = 28
Then
= =
4(9+7) = 36+28 = 64
open the parentheses, then simplify.
Sales tax: tax rate * cost before tax = 6% * $299.00 = $ 6*299.00/100 = $ 17.94
Total bill = cost before tax + tax = $299.00 + $17.94 = $ 316.94
