When Cat sold her car for $14,000, she put all of the money into a savings account. If the account earns 3.9% interest, how many YEARS will it take her to earn $1365 in interest?

Roughly 7.35169 years

Step-by-step explanation:

So we want an increase of money of $1365

So our target value is 15,365

Let's model the expression: target = initial_value * (1.39)^y, where y is years

This should immediately spark logarithms into your head

Use change of base formula:

y = 7.35169 years

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
