Assuming the logarithm is base

, you have
11)
3x = 180
x = 60
12)
6x + 18 = 180
6x = 162
x = 27
X can equal -7 or 1
X = -7 and 1
Answer:
n/4-6
Step-by-step explanation:
n/4-6
This is the expression because we need to divide n by 4 and subtract 6
The number is 68
68 divided by 4= 17
17-6=11
Slope formula : (y2 - y1) / (x2 - x1)
now pick 2 points on ur line...
(1,2)......x1 = 1 and y1 = 2
(3,0)......x2 = 3 and y2 = 0
now sub
slope = (0 - 2) / (3 - 1) = -2/2 = -1 <== ur slope is -1
