Answer:
x = 2 or x = 4
Step-by-step explanation:
Solve: 2 log x = log 2 + log(3x - 4)
log (x^2) = log 2 + log (3x - 4)
log (x^2) = log [2*(3x - 4)]
x^2 = 2*(3x - 4)
x^2 = 6x - 8
x^2 - 6x + 8 = 0
factor:
(x - 2 )(x - 4) = 0
x = 2 or x = 4
D because you have to use absolute value to solve.
Answer:
We have the following function:
f (x) = 5 • 2 ^ x
We can make a table to represent the function.
For this, we will evaluate the function for some values of x.
We have then:
f (0) = 5 • 2 ^ 0 = 5 * 1 = 5
f (1) = 5 • 2 ^ 1 = 5 * 2 = 10
f (2) = 5 • 2 ^ 2 = 5 * 4 = 20
f (3) = 5 • 2 ^ 3 = 5 * 8 = 40
f (4) = 5 • 2 ^ 4 = 5 * 16 = 80
f (5) = 5 • 2 ^ 5 = 5 * 32 = 160
Answer:
The table that represents the function is:
0 5
1 10
2 20
3 40
4 80
5 160
Answer:
1-True
2-True
3-False
Step-by-step explanation:
1- All negative numbers are <0 and to the left on a number line. All positive numbers are >0 and are on the right of a number line.
2- When the number line moves to the right, the number gets larger.
3- You could have a negative number that is smaller than another number, but its distance from 0 could be greater. For example, -12 < 2. However, -12 is 12 places away from zero on the number line, but the number 2 is only two places away from zero on the number line.
