Answer: 16a² + 15a + 9

Step-by-step explanation:

16a² + 15a + 9 = 0

Then plug into the quadratic formula which I attached.

a = -(15) ± √ (15)²- 4(16)(9) / 2(16)

a = -15 ± √225 - 576 / 32

a = -15 ± √-351 /32

a = -15 ± i√351 /32

*FYI: It is divide by 32

The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y $\leq$ -3x+8

Jet001 [13]

Return rate, r = 3% = 0.03
x = initial investment
b = final balance

After 1 year, the balance i
b = initial investment + interest
b = x + r*x = (1 + r)*x

Because r = 0.03,
b = 1.03x (after 1 year)
