Answer:

f(x)= 4x+9

F(x)=1/x

Step-by-step explanation:

An odd function accomplish the following condition:

f(-x) = -f(x) (1)

By checking (1) on each of the next functions, we have:

f(-x) = (-x)^3 - (-x)^2 $\neq$ -f(x) = - (x^3- x^2)

f(-x) = (-x)^5 -3(-x)^3 + 2(-x) $\neq$ -f(x) = -x^5 +3x^3 +2x

f(-x)= -4x +9 = -f(x)

F(-x) = -1/x =-F(x)

Answer: option 2 is the better option

Step-by-step explanation: well in this case as you are trying to find the individual prices of the candy bars, you would divide the total price by the amount of candy bars. So in this case for the first problem, you would take the total price: $6.75 and divide it by 10. The answer to this would be .675 but you would round it up to .68 so that you have a two digit decimal. Therefore the answer is .68 cents for each candy bar.

you would repeat this process for the second problem. Total price: $7.25 divided by 12 (candy bars). The answer in this problem would then be .60 cents per candy bar. Once we see how much each would be, it is just a matter of seeing which price is higher. In this case, the second option is the better option.

Sorry this was long, that's how i explain things, but i hope this helps

OlgaM077 [116]

Answer:

$about \: 1.01551$

Step-by-step explanation:

No it isn't, because:

${1.08}^{ \frac{1}{5} } = { \frac{108}{100} }^{ \frac{1}{5} } = { \frac{27}{25} }^{ \frac{1}{5} } = \sqrt[5]{ \frac{27}{25} } = 1.01551$

Seventeen members of Tim's family are going to an amusement park during the week of their family reunion. Adult tickets cost $34

baherus [9]

Answer:

Step-by-step explanation:

Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.

We have $34x + $31.5(17 - x) = $558.

$34x + $31.5(17 - x) = $558

$34x + $535.5 - $31.5x = $558

$2.5x = $22.5

x = 9

Hence the answer is c.

we know,

% change = (final- initial) / initial * 100

=(1125-2050)/1125 *100

=45.122%

Hence, percentage change be 45.122% decrease.
