The demoin is all real numbers greater than 6
Answer:
1.3917
Step-by-step explanation:
logb 15 =
We know that log (ac) = log a + log c
logb 15 = logb (3*5)
= logb (3) + log b (5)
logb(3) = 0.5646 and logb(5) = 0.8271
= 0.5646 + 0.8271
1.3917
Answer:
(-2, 3).
Step-by-step explanation:
x + 3y = 7
2x + 4y = 8
1 . x = 7 - 3y.
2. 2(7 - 3y) + 4y = 8
3. 14 - 6y + 4y = 8
-2y = -6
y = 3
4. Substitute y in the second equation:
2x + 4(3) = 8
2x = -14
x = -2..
