Question

Please can someone help me with this math problem my brother broke his arm and sadly have to do this math work.

Answer 1

it's d

rip u for his homework and i hope your brother gets better soon. the correct answer is (d)

Answer 2

A.

`\sf Slope = (y_2-y_1)/(x_2-x_1) \ where \ (x_1,y_1) \ and \ (x_2, y_2) \ are \ points`

Take two points for red slope: (0,100),(5, 250)

`\sf Red \ slope = (250-100)/(5-0) = 30`

Take two points for blue slope: (0,500),(5, 250)

`\sf Blue \ slope = (500-250)/(0-5) = -50`

Slope represents the balance in dollars per number of deposits.

B.

Red y-intercept = 100

Blue y-intercept = 500

The y-intercept represents balance in dollars when no deposits made.

C.

For Red Line:

• y - 100 = 30(x - 0)

• y = 30x + 100

For Blue Line:

• y - 500 = -50(x-0)

• y = -50x + 500

D. point of Intersection: (5, 250)

E. A system of Linear equations have only one solution.
