Cassie added two numbers together on her calculator for her biology homework. The calculator showed the sum as 9.62E-6. She knows she used 0.000009535 as one of the numbers. What number did she add to 0.000009535 to get 9.62E-6? A. 8.5 × 10-8 B. 1.8 × 10-8 C. 1.8 × 10-6 D. 8.5 × 10-6 the answer is ...
8.5 × 10-8

maybe i can

i think the correct option is the second option.

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
