Answer:
-5
Step-by-step explanation:
Let's rewrite the given sequence :1/3, 1, 5/3, 7/3 . Notice that 1 =3/3, then
1/3, 3/3, 5/3, 7/3,...We also notice that the common difference d is equal to:
3/3 - 1/3 = 2/3 and 5/3 - 3/3 = 2/3 & 7/3 - 5/3 = 2/3
Hence this sequence is NOT A GEOMETRIC PROGRESSION but an ARITHMETIC PROGRESSION,instead with d = 2/3
Answer:
Step-by-step explanation:
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
5x + 2y = 7
6x –2y = 4
Why is this multiplication allowed? (1 point)
Because the entire equation was multiplied by the same number, the equation remains the same.
What variable will be eliminated when the equations are combined after the multiplication? (1 point)
The Y variable
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
11x = 11
Solve the equation for x. (1 point)
X = 1
What is the solution to the system of equations? (1 point)
X = 1 and Y = 1 so the answer is (1, 1)
(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)
Answer:
1/4
Step-by-step explanation:
There are two possible outcomes when we flip a coin, heads or tails
P(heads) =1/2
Then we flip again
P(heads) =1/2
P (heads, heads) = P(heads) * P(heads) since they are independent events
=1/2(1/2 )= 1/4
