PXrXt /100 is the formula
Answer:
If x is an integer, then for values of x ≤ 0 would -x be positive.
General Formulas and Concepts:
<u>Math</u>
Step-by-step explanation:
We know that integers comprise of the number line from -∞ to ∞. We can have numbers like -3, -2, -1, 0, 1, 2 ,3.
If we say that x is an integer, and that -x must be positive, then that means the integer x must be negative, because a negative times a negative is a positive.
∴ x can only be negative integers, thus giving us x ≤ 0.
So if 2 is the first term then if n=1 then n+1=sequence so far but
second term is 9 so if n=2 then the 2nd term=9
you must use trial and error to find
so it is
7n-5 so if n=1 then
7(1)-5=7-5=2
if n=2 then
7(2)-5=14-5=9
sucess
the equation is 7n-5
Answer:
Step-by-step explanation:
Let the original fraction be 
Then adding 1 to the numerator gives
= 
( cross- multiply )
⇒ y = 5x + 5 → (1)
Subtracting 1 from the denominator gives
= 
(cross- multiply )
y - 1 = 7x → (2)
Substitute y = 5x + 5 into (2)
5x + 5 - 1 = 7x ← subtract 5x from both sides
4 = 2x ⇒ x = 2
Substitute x = 2 into (1)
y = (5 × 2) + 5 = 10 + 5 = 15
Hence original fraction =
