Step-by-step explanation:
<u>Step 1: Define Systems</u>
6x - 5y = 15
x = y + 3
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: 6(y + 3) - 5y = 15
- Distribute 6: 6y + 18 - 5y = 15
- Combine like terms: y + 18 = 15
- [Subtraction Property of Equality] Subtract 18 on both sides: y = -3
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x = y + 3
- Substitute in <em>y</em>: x = -3 + 3
- Add: x = 0
D, its (x,y) and (8.2,5.7) are the only ones that match up

he probability that a randomly selected 40-year-old female will live to 41 years old is 0.998 according to a study. What is the probability that none of two randomly selected 40-year old females will live to be 41 years old?
Answer:
sqrt(10)
Step-by-step explanation:
Since the second number ends and does not continue it wouldn't be the second one, and since the third is able to be predicted it wouldn't be the thrid one either and since the fourth one is 7 and is a whole number the only answer choice possible would be the first one.
