Answer:
Step-by-step explanation:
The profit function is:
Where
P is the profit
and
d is the number of units sold
Now, there is a 50% increase in number of units sold, so d will become:
50% = 50/100 = 0.5
d + 0.5d = 1.5d
So, we have to replace "d" with "1.5d" in the function, which makes it:
From the equations shown, last answer choice is correct.
Answer:
4-x
Step-by-step explanation:
The number 4 is being decreased by a number. Decreased means that something is being subtracted. Since you do not know the number, the number will be x.
Answer:
x=0 x = 1/6
Step-by-step explanation:
5x -30x^2 = 0
Factor out the greatest common factor which is 5x
5x(1 -6x) =0
Use the zero product property
5x =0 and 1-6x =0
x =0 -6x = -1
x = -1/-6
x = 1/6
Answer: OPTION B.
Step-by-step explanation:
1. By definition, the line intercepts the x-axis when y=0. Therefore, you must susbtitute y=0 into the equation of the line given in the problem and solve for x, as you can see below:
2. Knowing that the x-intercept of the line from the equation and is -2 and the x-intercept from the description is (0,0), you can conclude that the correct option is B.
