Answer:
k=5
Step-by-step explanation:
We are provided with function, f ( x ) = 3
+ kx − 13
which is divided by x+4 gives 15.
Here,
since f(x) is divided by x+4 so we can put :
x+4 = 0
x= -4
Putting this in f(x) -----> f(-4)
f(x) = f(-4) = 3 (
) + k(-4) − 13
f(-4) = 3(16) - 4k - 13
f (-4) = 48 - 4k - 13 ------------------------------------------Equation 1
Since, when f(x) is divided by x+4 , the remainder is 15 so we can say,
f(-4) = 15
putting in equation 1
f (-4) = 15 = 48 - 4k - 13
48 -4k - 13 = 15
35 - 4k = 15
35 - 15 = 4k (Moving - 4k on right hand side and 15 on the left)
or 20 = 4k
or 4k = 20
k =

Answer:
A Rational number is a number that can be written as a ratio in fraction form.
An Irrational number is a number that, when in decimal form, does not terminate or repeat.
Step-by-step explanation:
1.485 can be written as 1 485/1000 - it is rational
0.187345911... continues on and does not repeat - it is irrational
333.051422218... continues on and does not repeat - it is irrational
0.2268715 can be written as 2268715/10000000 - it is rational
1.24 can be written as 1 24/100 - it is rational
Answer:
If your payment didn’t go through, change your preferred payment method/add another payment method.
For example, if your preferred payment method is your bank account, we'll always try to use your bank account first for payments. If there's an issue with your bank account, you can change your preferred payment method to a different one, such as a debit or credit card. If you only have a card registered on your account, try adding and confirming a bank account.
