Using the 4 points that are given as the solution on the graph, replace t he x and Y in the original equation to solve and see which is the greater value.

Point (0,3) P = -0 +3(3) = 0+9 = 9

Point (1,4) P = -1 + 3(4) = -1 +12 = 11

Point (0,0) P = -0 + 3(0) = 0 + 0 = 0

Point (3,0) P = -3 + 3(0) = -3 + 0 = -3

The correct solution to maximize P is (1,4)

All log graphs contain the points (1,0), (a,1), and (1/a,-1). True . False.

Bumek [7]

The correct answer is: True

Explanation:
1. $log_a1 = 0$ (Straightforward)
2. $log_aa = 1
$ (log to base of itself is always 1)
3. $log_a \frac{1}{a} = log_aa^{-1} = -1(1) = -1$ (Using log power property)

Hence the correct option is True.

Chet needs to buy 4 work shirts, all costing the same amount. The total cost before Chet applies a $25 gift certificate can be n

Alborosie

Let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount. - Credits, Taskmasters and Hegans

Solve: A = 4pir2 for r.

Airida [17]

r means radius so it can't be negative.

<=>

A = 4 pi r²

r = sqr (A / 4pi)
