Answer:
4
Step-by-step explanation:
Since the base is the same, 3, you can just get rid of it using the principles of log. What you're left with is:
2x + 1 = x + 5
Now just solve for x:
2x - x = 5 - 1
x = 4
Answer:
The slope of a horizontal line is zero
Step-by-step explanation:
All horizontal lines are parallel to the x-axis.
The x-axis has a zero slope.
All parallel lines have the same slope.
Therefore the slope of a horizontal line is zero.
This means there is no rise in y.
So rise over run will become:
0/run=0
To find the missing value divide both sides by -7:
28/-7 = 4
The missing value is 4
70. 180-120=60, and 180-60+50=70
