Answer:
That would be :
4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y)
PROOF: y + 5x = x² + 10
(4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10
0 = x2 – 9x + 20 (liked terms are grouped and simplified)
PROOF: 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20
Solving:
x² - 9x + 20 = 0
x² - 5x - 4x + 20 = 0
(x - 5) (x - 4) = 0
⇒ x = 4 (as question says) OR x = 5

Answer:
That's the way it should be graphed
Answer:
Let's try and figure it out yearly:
So for the first year the deposits would amount to 40 * 12 = $480
Now since the interest rate is applied yearly we will assume that the interest rate will be applicable to the amount that is left after the first year of deposits
So that would be 889.98 - 480 = 409.98
409.98 * 14.99 % = 61.45
The new amount owed for the second year would be 409.98 + 61.45 = 471.43
So by the end of the second year the debt would of been wiped clean with $8.57 to spare.
So the answer would be 24 months
