Answer: 21
12
Log8(8 is under the log) the answer is 7
Step-by-step explanation:
Answer:
1. He traveled 3/ 10 by train
2. 3/4 is the greatest
Step-by-step explanation:
3/ 10 = Iorry
2/5 = taxi
? = train
2=4
5=10
4+ 3 = 7
10 + 10= 10
13/20
12/20
15/20
17/20
Step One
Factor f(x)
f(x) = (x + 5)(x - 2)
Step Two
The zeros occur when either (x + 5) = 0 or (x - 2) = 0
x + 5 = 0
x = -5
x - 2 =0
x = 2
Step 3
Record the zeros
(-5,0) or (2,0) <<<<<< answer.
Find the domain of
y = log(x + 3)
Logarithms can only be taken for positive numbers. So you must have
x + 3 > 0
x > – 3 ✔
So the domain of the function is
D = {x ∈ R: x > – 3}
or using the interval notation
D = (– 3, +∞)
I hope this helps. =)
5x + 2 -x = -4x
4x +2 = -4x
2 = -4x -4x
2 = -8x
x = - 1/4
hope this helps
