Answer:
The rule is 3(5)^(n-1) where n is the term number.
Step-by-step explanation:
The constant multiplier = 15/3 = 5.
Checking that this is correct 75/15 = 5, 375 / 75 = 5.
So for term number 1 , the value is 3 , the expanded form is 3 * (5)^(1-1) and the simplified form is 3*5^0 = 3.
Term number 2, the value is 15 , the expanded form is 3 * 5^(2-1) and the simplified form is 3 * 5^1 =15.
The other rows are calculated in the same way.
This is a Geometric sequence with common ratio 5.
The rule for the sequence is 3(5)^(n-1).
1 3/7 - 4/5
10/7 - 4/5
(50/35) - (28/35)
(50-28)/35
22/35
The answer is 22/35
Substitute -x-5 for y
Gets you:
3x-2(-x-5)
Distribute the 2
3x-(-2x-10)
Distribute the -1
3x+2x+10
Combine like terms
5x+10
Subtract 10 from both sides
5x=-10
Divide by 5
x = -2
