Answer: it will take 2 months for both accounts to have the same amount and the in each account would be $65

Step-by-step explanation:

Let x represent the number of days that it will take the amount in either accounts to be the same.

Let y represent the amount in Christiana's account after x days

Let z represent the amount in Marlena's account after x days

Christiana opened her account with $45 and plans to deposit $10 every month. This means that in x days, the amount in Christiana's account would be

y = 45 + 10x

Marlena opened her account with $35 and plans to deposit $15 every month. This means that in x days, the amount in Marlena's account would be

z = 35 + 15x

To determine the number of months before the amount in both accounts becomes the same, we will equate y to z. It becomes

45 + 10x = 35 + 15x

15x - 10x = 45 - 35

5x = 10

x = 10/5 = 2

The amount would be

45 + 10×2 = 45 + 20 = $65

Answer:

After 2 months their accounts have same amount of money that is $65.

Step-by-step explanation:

Initial amount Christiana deposits = $45

Amount Christiana deposit  each month = $10

Initial amount Marlena deposits = $35

Amount Marlena deposit  each month = $15

Let x be the number of months after which amount in accounts is same.

Christiana balance in x months = 45 + 10x

Marlena balance in x months = 35 + 15x

After x months their balance becomes equal i.e.

                                 45 + 10x = 35 + 15x

dividing both sides by 5

                                  9 + 2x = 7 + 3x

                                         x = 2

After two months:

Christiana balance  = 45 + 10(2)

                                 = $65

Marlena balance = 35 + 15(2)

                             = $65

2. What would a point on the horizontal axis represent? What about on the vertical axis?
Nikitich [7]
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.


A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin. The numbers on a coordinate grid are used to locate points.
