Answer:

Step-by-step explanation:
Linear function:
A linear function has the following format:

In which m is the slope and b is the q-intercept.
One week you charged $4 per guest and averaged 80 guests per night. The next week you charged $10 per guest and averaged 44 guests per night.
This means that we have these following points: (4,80), (10,44).
Finding the slope:
With a pair of points, the slope is given by the change in q divided by the change in p.
Change in q: 44 - 80 = -36
Change in p: 10 - 4 = 6
Slope: 
So

Finding b:
We replace one of the points. Replacing (4,80).



So

I'm here buddy,
so, let's take the value of the two bags with equal weight as x.
= x + x + (x +
) = 
= 3x +
= 
= 3x =
- 
( let's take the LCM of 4 and 5 = 20
= 3x =
- 
= 3x = 
= x =
÷
=
×
= 
So, the weight of the equal bags are
and the weight of the third bag ( heavy one ) is
+
=
+
= 
1st bag =
kg
2nd bag =
kg
3rd bag =
kg
Hope it helps...
Answer:
B
Step-by-step explanation:
Rate, in this case, is mph which can be written as miles/hours.
HTH :)
#4 is actually f(x) + 18. #5 is f(x) + 201, #5 is f(x) + 316.
