Answer:
x=8
Step-by-step explanation:
If the value of x varies directly as the value of y we can say they are directly proportional. This implies that when y increases x will increase too, and when y decreases x will also decrease.
If x=16 when y=3/4 we can write their relation as:
x/y = 16/(3/4) = 16*(4/3) = 64/3
So, for every value of y, the ratio x/y must maintain equal to 64/3 because both values are proportional.
Now we can see what happens to x when y varies. If y=3/8:
x/(3/8) = 64/3
Multiply both sides by 3/8 to eliminate the 3/8 in the denominator.
x/(3/8) * (3/8) = (64/3) * (3/8)
See that we have a 3 multiplying and another dividing, we can eliminate them.
x = 64/8
x = 8
So, if y decreases to 3/8 x will decrease to 8. Notice that y is decreasing in a half as 3/8 is the half of 3/4, and x is also decreasing in a half from 16 to 8, what makes sense.

Step-by-step explanation:
From the information given from the question, the initial function representing her photo sharing is:
F(x) = 3(4)^2
F(x) = 3 × 16 = 48 photos
Then the new graph has an upward shift ( translation) of 45 units
The new function representing her photo sharing is:
F(x) = 3(4)^2 + 45
F(x) = 48 + 45
F(x) = 93 photos.
Answer:

Answer:
22.28
Step-by-step explanation:
the inequality would be 29.99+0.18x≤34 because 29.99 is the constant. and the 0.18 is the 'slope' if this were being graphed. and it and it can be equal to but no more than $34.
you subtract 29.99 from both sides
0.18x=4.01
divide by 0.18
x≤22.28
but you cant send a partial text so it rounds down to 22
Answer:
a) 
b) 
Step-by-step explanation:
From the question we are told that:
Rate r=90 units per hour
Setup cost =20
Operating Cost =26
Units=40000
Generally the equation for Total cost is mathematically given by
