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 =

k = 5</h2>
For a width of 25, the length will also be 25, so the area is 25² = ...
625.
_____
The rule is
area = width×(50 -width)
Marlene owes a total of $20,710.75 in taxes.
If we are using the same tax schedule then $95,000 belongs to this bracket:
Over - But not over - of the excess over -
$77,100 but not over $160,850.. 15,698.75 plus 28% 77,100
Get the 28% of the difference between $95,000 and $77,100:
$95,000 - $77,100 = $17,900
$17,900 * .28 = $5,012
$15,698.75 + $5,012 = $20,710.75
Answer:
true
2. If ab = 0, then a = 0 or b = 0. This statement is true. It is a property of the real numbers which was stated in class
