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:
$188.50
Step-by-step explanation:
i got this answer by dividing $1,508 by 8 and you would get 188.5 which would turn into $188.50 and that is how much each person would get.
I hope this helps.
To solve this equation with algebra
4/7 = 1/x
(4/7)x = (1/x)x
4x/7 = 1
(4x/7)7 = 1(7)
4x = 7
4x/4 = 7/4
x = 1.75
1.75 yards of fabric are needed to make 1 dress.

Answer:
c=24
Step-by-step explanation:
c/3 = 8
Multiply each side by 3
c/3 *3 = 8*3
c=24
<em>Answer:</em>
<em> 56 tablets</em>
<em>Step-by-step explanation:</em>
Jonah knows that Mr. Robinson needs 14 tablets for a week's supply of an anti-inflammatory drug.
<em>Mr. Robinson is going on vacation and needs a 4-week supply. </em>
<em>So </em><u><em>multiplying 4 with the weekly supply</em></u><em> will yield the required result. </em>
So, number of tablets Jonia needs to fill is,
=4\times 14
=56
<em>Therefore, Jonah needs </em><u><em>56 tablets</em></u><em> in order to fill his prescription</em>
