Answer:
α + β = - ba and αβ = ca.
⇒ x2 + bax + ca = 0 (Since, a ≠ 0)
⇒ x2 - (α + β)x + αβ = 0, [Since, α + β = -ba and αβ = ca]

Answer:
2. Reason: Addition Property of Equality
3. Statement: 3x=18
4. Reason: Division property of Equality
5. Statement: x=6 Reason: Simplifying.
Step-by-step explanation:
I'm pretty sure this is correct.
No the inequality symbol only changed when you divide a negative number from both sides.
Answer:
0.40
Step-by-step explanation:
Sin(T) is Opposite over Hypotenuse, which is RS/ST.
ST = sqrt(43) so we can plug that in.
To find RS, use the Pythagorean theorem, so, 6^2+ (RS)^2= 43.
36 + (RS)^2 = 43
RS^2 = 7
RS = sqrt(7)
Thus, Sin(T) = sqrt(7/43) or 0.40
