Answer: 5x(x-1)
Step-by-step explanation:
2(x2 - x) + 3 (x2 - x)
5x(2 power) - 5x
= 5x(x - 1)
Answer:
25/6
Step-by-step explanation:
The direct variation tells you that y is proportional to x. That means a reduction by a factor of 5/6 as x changes from 6 to 5 will result in a reduction of y by the same factor.
y = (5/6)(5) = 25/6
I think it would be y plus 3 times 2 equals 5x. I'm not sure if that is what they are asking for.
The maximum profit is the highest point on the curve at (3, 45), and since the y-value is the profit in hundreds of dollars, the maximum profit is $4500.
The shop is making a profit as long as the curve is above the x-axis, so this is over the given interval (0, 10).
The maximum profit is earned at x = 3, and the x-value is the money spent on advertising in hundreds of dollars, so this means that $300 was spent of advertising.
