Answer:
x = (7 + √133) / 6
Step-by-step explanation:
0 = log₉ (3x + 2) + log₉ (x − 3)
Use log rules:
0 = log₉ ((3x + 2) (x − 3))
Raise 9 to both sides:
1 = (3x + 2) (x − 3)
Simplify:
1 = 3x² − 7x − 6
0 = 3x² − 7x − 7
Use quadratic formula:
x = [ -(-7) ± √((-7)² − 4(3)(-7)) ] / 2(3)
x = (7 ± √133) / 6
Since x > 3:
x = (7 + √133) / 6
x ≈ 3.089
Answer:
33 °C
Step-by-step explanation:
Put 92 where F is in the equation, and solve for C.
92 = 1.8C +32 . . . . substitute for F
60 = 1.8C . . . . . . . . subtract 32
60/1.8 = C ≈ 33.33 ≈ 33 . . . . . divide by the coefficient of C, round the result
The temperature is about 33 °C.
Answer:
Step-by-step explanation:
Cross multiply,
q(t+3) = 2 - 4t
Use distributive property: a*(b + c) =(a*b) + (a*c)
qt + 3q = 2- 4t
qt + 4t + 3q = 2
qt + 4t = 2 - 3q
t(q + 4) = 2 -3q
