A local bakery sells cookies for 5.50 per pound and brownies for 7.50

Mathematics
1 answer:
uysha [10]3 years ago
6 0

Answer:

I may be wrong but i think the answer is D

Step-by-step explanation:

We know that y=10, so if we were to multiply 10 by 7.50, it would be 75, not 63, so A and B wouldn't be correct. and we don't know the value of x, so I think D is the best answer.

An entrepreneur estimates his total profit (total revenue minus total cost) for his proposed company as p(x) = x3 − 4x2 + 5x − 2
nikitadnepr [17]
To "break even" means that the costs are equal to the money made, so profit would have to be 0. Therefore, we can rewrite the equation to be
0 = x3 -4x2 +5x -20

From here, all you have to do is factor to be able to solve for the values of x

First, since the first two numbers both have an x2, we can factor that out
x2(x-4) + 5x -20 = 0

The next two can factor out a 5
x2(x-4) + 5(x-4) =0

Since both of these terms share an (x-4), they can be factored to become:
(x-4) (x2 +5) = 0

So now we just solve for x, and get x = 4, and +- (sqrt) 5i

Since 4 is the only answer present in the options (and since 5i is a non-real number), the answer would be 4

ANS: D

Oman said that it is impossible to raise a number to the power of 2 and get a value less than the original number. Do you agree
Eva8 [605]
Oman is wrong, if you raise any decimal number less than one to a power of 2 the number just gets smaller
