Q: write the rules for determining the sign of the product when multiplying integers. then, write the the rules for determining the sign of the quotient when diving integers. i don't need a full answer just me understand what they mean by the "sign of the product/sign of the quotient"

Here is the rule for multiplication:

Negative * negative = positive; example (-2)*(-2) =+4

Negative* positive = Negative. example (-2)*(2) = -4

Positive * negative = negative; example (2)*(-2) =-4

Positive * positive = Positive ; example (2)*(2) =4

Sign for quotient in division

Negative / Positive = NEgative ; (-2)/(2) =-1

Positive / negative = negative; (2)/(-2) =-1

Negative / negative = positive; (-2)/(-2) =1

positive / positive = positive; (2)/(2)=1

The sign of the product means if it is negative or positive after multiplying. Example: -2 x -2 = 4.

Hope I could help! Let me know if there's anything else you need. Brainliest is greatly appreciated!

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
