3n + 7 ><span> 4n
-3n -3n
7 > n
n</span> < 7
X=2
subtract 5x on both sides
-2x=-4
divide by -1 on both sides
2x=4
divide by 2 on both sides
x= 2
Answer: -3
Step-by-step explanation:
The common ratio of the geometric sequence –4, 12, -36,... is -3.
12/(-4) =-3
-36/(12) = -3
They both multiply -3 for the next number.
The rate of change of the linear equation is 
Explanation:
The given two coordinates are
and 
To determine the rate of change, let us use the formula,

Substituting the coordinates in the equation, we get,

Simplifying, we have,

Dividing, we get,

Thus, the rate of change of the linear equation is
