Answer:
see explanation
Step-by-step explanation:
given that V is directly proportional to u and inversely proportional to f , then the equation relating them is
V = 
← k is the constant of proportion
(a)
to find k use the condition when u = 1 and f = 3 , V = 
, then
= 
( cross- multiply )
6k = 3 ( divide both sides by 6 )
k = 
= 
V = 
← equation of proportion
(b)
when f = 4 and V = 1 
= 
, then
= 
= 
( cross- multiply )
4u = 40 ( divide both sides by 4 )
u = 10

Step-by-step explanation:
$40 per day represents the slope
<u>Finding the y-intercept:</u>
<u>The function is then:</u>
Answer:
0
Step-by-step explanation:
8x + 4 = 3x - 3 +7
u first expand the bracket as I have done above
then u evaluate those who have like terms close like -3 + 7
8x + 4 = 3x + 4
then u group like terms ie. the values with the variable x on one side of the equation and the ones without x on the other side of the equation
8x - 3x = 4 - 4
8x - 3x = 0
5x = 0
then u divide both side by the coefficient of x
0/5 but any number divided by 0 is 0, so x = 0
