So she has 400 and 500 so far.
now if she were to have an average of 2300 for the next 5 years, that means some years she made more, some she made less, but in the 5 years run, she made 2300 * 5 or 11500 total.
Neverminding the lows and highs, if we bundle up the 11500 bucks and divide by 5, that'd 2300, which is what's called the average, the average amount doesn't take into account that some numbers are higher than others, it kinda just flattens them out.
so in total she would have made 11500 in each account.
so in the account with 400, she needs 11100 more, how much will it be 1100 for the next three years on average? 11100/3 or 3700.
so if she earns 3700 each year, for the next 3 years in the account with 400 already, she'd have 11500 bucks in 5 years with an average of 2300.
now let's look at the 500 account, she needs 11000 more, how much will it be for 11000 for the next three years on average? 11000/3 or about 3666.67.
so if she earns 3666.67 each year, for the next 3 years, she'd have 11500 bucks in 5 yeas with an average of 2300.
I'm going to go right ahead and assume that we're talking about a linear equation.
The linear equation passing through the points given is y=3x+4, since it satisfies both of the points given.
-2 or -2/1 because the ratio is y over x and the line is going down 2 (-2) every time it goes to the right once (1)
Answer:
It will take Rosa 5 and a half (5.5) weeks to have the same amount of money in both accounts.
Step-by-step explanation:
For this problem, we will have to set two expressions equal to each other. The first expression will represent Rosa's saving account, which already has $117 in it. Every week (
), she adds $21 to her savings account:

The second expression will represent Rosa's checking account. Rosa's checking account already has $95 in it. Every week (
), she adds $25 to her checking account:

Now that we have our two expressions, set them equal to each other. This is our equation that will be used to find the number of weeks (
) it takes until Rosha has the same amount of money in both accounts:

Subtract
from both sides of the equation:

Subtract
from both sides of the equation:

Divide both sides of the equation by the coefficient of
, which is
:


So it will take five and a half weeks for her accounts to have the same amount of money.

Check your work by substituting
into the initial equation:



Since the accounts have the same amount, the answer is correct!
Answer:
undefined
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 9-3) / ( 2-2)
= 6/0
When we divide by zero, the result is undefined
This means the slope is undefined
