Answer:
Step-by-step explanation:
The nth term of the sequence is
To get the first term, substitute n=1,
To get the second term, substitute n=2,
To get the third term, substitute n=3,
The sum of the first three terms is
We could also use the formula
to get the same result.
Answer: x = 0 or x = 2
Step-by-step explanation:
To solve this, we must note that the two equations speaks of a single function of y. So
y = 2x - 3 = x² - 3
So from.here we can equate the two together and solve for x.
x² - 3 = 2x - 3, biw convert to a quadratic expression
x² - 2x - 3 + 3 = 0
x² - 2x = 0
Now factorize
x( x - 2 ) = 0, so solving for x
x = 0 or x = 2. .I believed getting the 2 won't be a problem
When x - 2 = 0
Then x = 2.
6.2w = 18.6....divide both sides by 6.2
w = 18.6 / 6.2
w = 3 <==
