You withdraw 260$ from your bank account in 5 trips to the ATM. what is the average change in your account balance for each trip
N76 [4]
To find the average over 5 times, we have to divide the total by 5. Therefore, 260/5 = 52 = the average change in your account balance each trips. 260 = amount of money you withdraw, 5 = number of trips made by the ATM. We need to divide due to that if something is spread out equally 5 times, what you get in one time clearly won't be all of it

How would u do 1 over 3 y + 1 over 4 = 5 over 12? I forgot my notes:(
malfutka [58]
Is it
\frac{1}{3y} + \frac{1}{4} = 5
or
\frac{1}{3} y + \frac{1}{4} = 5
?

both start out the same, just remember what you do to one side you have to do to the other, so subtract both sides by 1/4, then you want to get y alone, so either divide or multiply the 3 on both sides! let me know which it is and I can help you out more

[edit] it's the second, and not going to use cross multiplication.
added a picture that walks you through it :)

If the domain of f(x)=-x² is integer values of x such that -3≤x<0, find the range.
slamgirl [31]

The range is the resulting y-values we get after substituting all the possible x-values.

\text{The domain:}\\\\-3\leq x < 0\to\{-3,\ -2,\ -1\}\\\\\text{The range:}

Substitute the values of x to the equation of the function:

f(-3)=-(-3)^2=-9\\\\f(-2)=-(-2)^2=-4\\\\f(-1)=-(-1)^2=-1\\\\\boxed{\{-9,\ -4,\ -1\}}

Owen runs a pet store that sells rabbits. He wants to ensure he has more than 1 pound of dry food for every four rabbits he has
Lana71 [14]

Answer:

B) Owen can have a maximum of 22 rabbits in the store.

Step-by-step explanation:

Consider:

"He wants to ensure he has more than 1 pound of dry food for every four rabbits he has in the store."

It means, at least 0.25 pounds per rabbit. (1 pound divided by four)

"He currently has 5.7 pounds of dry food."

Inequality (r is the number of rabbits):

5.7\leq  0.25r\\22.8\leq r

According to the inequality, he can only have a maximum of 22 rabbits.
