Answer: no solution
Reason: the 9x on one side cancels out the other, and 3 is not equal to 7.
Answer:
667 boxes
Step-by-step explanation:
-Given that x is the demand and p the price.
-Let k be the constant of proportionality. We then express the inverse relationship as:
#We substitute for the new x value and the calculated k to solve for p:
Hence, the demand at a price of $6 is approximately 667 boxes
Answer:
D) [2,5]
Step-by-step explanation:
Multiply f(x) and g(x) to get (f•g)(x). It is a semicircle that has all values from x=2 to x=5
Answer:
C and B.
Step-by-step explanation:
f(x) = 4 - x^2.
The degree of f(x) is 2, which means it is a quadratic graph. The coefficient of x^2 is negative, which means the curve is pointing downwards. The only curve that satisfies this is Graph C.
f(x) = 2^x + 5.
Notice that 2^x is positive for all real values of x. Therefore the answer is Graph B.
In the second one I'm pretty sure you just measure the length of the points.
