Answer:
1. -x+12=8 =-x=8-12-= -x=-4 dbs= 4/x
1.) 4, 2, 1, 1/2, 1/4,... 2.)2, 6, 18, 54, 162, ...
3.) -4, -16, -64, -256, ... are geometric sequences because common ratio is same. Example: 1.) ratio of 1st and 2nd term is 1/2. Similarly ratio of 3rd and 4th term is 1/2 and so on.
Answer:
6 and 7
Step-by-step explanation:
The answer is B because 90 to 30 is 3 over 2
The midpoint of the given expression is (2, 5)
<h3>Midpoint of coordinates</h3>
The formula for calculating the midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;
M(x, y) = {(x1+x2/2), y1+y1/2}
We are to find the midpoint of A (-3,4) to B (7,6) since it is in the ratio 1:1
Substitute the given parameters
M(x, y) = (-3+7/2, 4+6/2)
M(x, y) = (4/2, 10/2)
M(x, y) = (2, 5)
Hence the midpoint of the given expression is (2, 5)
