Answer:
Step-by-step explanation:
Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be 
Because the sequence multiplies by 3 each time, The base number in that equation would be 
.
So 
of the equation would be:
.
Compare the 2 equations:
4, 12, 36
3, 9 ,27
The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is: 
.
Combine these 2 equations together and you get:
.
Lets smaller number is x
<span>The greater number is 8 more than the smaller number : x + 8
</span><span>The sum of two numbers is 72: x +( x + 8)= 72
answer
</span><span>x + (x + 8) = 72</span>
Answer:
3x+6>12
X=4
3x4=12+6=18
18>12
Step-by-step explanation:
Hi there!
A horizontal line has no slope, or the slope of 0.
Since a horizontal line is just a straight line across a point, and it never has an x intercept, the slope is always either "no slope", 0, or undefined.
Hope this helps!
Answer:
1. In order for Pattern B to be linear, the common difference of the number of dots between each step should be constant. As it is not constant, the pattern is not linear.
2. In order for Pattern B to be exponential, the common ratio of the number of dots between each step should be constant. As it is not constant, the pattern is not exponential.
3. In order for Pattern B to be quadratic, its sequence of second differences must be constant.
First differences:
Second differences:
Therefore, as the sequence of second difference is constant, the patten is quadratic.
The function for pattern B is: 
(where x is the step number)
