For this case we have that by definition, a direct variation is given by:

Where:
k: It is the constant of proportionality of the variables.
On the other hand, we have that the inverse variation is given by:

Where:
k: It is the constant of proportionality of the variables.
In this way, the correct option is:

Answer:
c = 150p + 1000
Step-by-step explanation:
We know the variable cost is 150 per phone, so the total cost will be ...
c = 150p +b . . . . for some value b
We also know the value of c for 8 phones, so we can find b:
2200 = 150(8) + b
2200 -1200 = b = 1000
Then the desired equation is ...
c = 150p + 1000
Answer:
D pi/4, 3pi/4
Step-by-step explanation:
Differentiate the function then equal it to zero and solve for the interval (see attached workings)
Answer:
where is the table
Step-by-step explanation:
Isolate the x. Do the opposite of PEMDAS.
−4 ≤ 11 −3x
First, subtract 11 from both sides
-4 (-11) ≤ 11 (-11) - 3x
-4 (-11) ≤ - 3x
-15 ≤ - 3x
Isolate the x. Divide -3 from both sides. Remember to flip the sign.
(-15)/-3 ≤ (-3x)/-3
-15/-3 ≤ x
5 ≥ x
x≤5 is your answer
hope this helps
