On the first day of the year, you have $700 in your bank account. you spend $35 per week. your friend starts the year with $450 in his bank account. he saves $15 per week. solve the equation 700 – 35w = 450 + 15w to find out how many weeks, w, it will take for you and your friend have the same amount of money in your accounts.

A number of weeks are 5.

So this is just a basic algebra equation where we need to solve for an unknown variable.

First we should put all the w's on one side and regular numbers on the other, so:

250  =  50w

If we divide by 50 on both sides, we get:

w  =  5

It will take 5 weeks for you and your friend to have the same amount of money in your back accounts.

Were the multiply choice?

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
