Answer:
She deposits $350 into the account at the beginning of the year.
Step-by-step explanation:
Let us assume that Keegan deposits $P into her savings account at the beginning of the year.
The account earns 3% simple interest each year and she has $360.50 in her account at the end of the year.
If Keegan did not make any additional deposits or withdrawals during the year.
So, we can write that
⇒ P = $350 (Answer)
Answer:
Condition 1: y>0
Condition 2: x+y>-2
Step-by-step explanation:
We are told that we have a set of points in the Cartesian system (i.e. x-y coordinate), so we can define our point as:
We are given two conditions and we want to create a system of inequalities. Now, generally speaking, inequalities are expressions relating mathematical expressions through 'comparison' (i.e. less than, greater than, or less/greater and equal to) usually recognized by ,
,
and
, respectively.
So in our case let set up our inequalities.
Condition 1: the y-coordinate is positive
This can be mathematically translated as
(i.e. is greater than 0, therefore positive)
Condition 2: the sum of the coordinates is more than -2
This can be mathematically translated as
(i.e. the summation of the two coordinates is greater than -2 but not equal to).
The system of inequalities described by the two conditions is:
