1. No answer ( may be due to incorrect question)
2. x = -3
y = 4
3. x= 4
y = 2
4.x = -63/40
y= -19/20
Step 1
Multiply equation 1 by the coefficient of x in equation 2
Multiply equation 2 by the coefficient of x I'm equation 1
(after completing this step you will derive equation 3 and 4 )
Step 2
Subtract equation 4 from equation 3
Step 3
Divide both sides of the equation by the coefficient of y
Step 4
substitute your value for y in equation 1 or 2
(after this you will derive the values of x)
Note : This method is for the Elimination of x

Answer:
Yes, it is true that 
is a factor of 
.
Step-by-step explanation:
Let us try to factorize
Let us try to make a whole square of the given terms:
--------------
Formula used above:
In the above equation, we had 
.
--------------
Further solving the above equation, taking 
common out of 
Taking 
common out of the above term:
So, the two factors are 
.
The statement that is a factor of is <em>True.</em>
Answer:
38 times
Step-by-step explanation:
A coin has two sides, so there is a 50% chance it will land on either side (assuming perfect conditions and that the coin cannot land vertically). With that in mind, if you flip a coin 76 times, 50% or 1/2 of the times the coin should land on tails. That is 36 times. (Once again, this is under perfect testing conditions. In real life, you probably wouldn't get an even split after only 76 flips.)
Hope this helps :)
Answer: 4, 6, 8, 9 and 10
Why?: What is the only composite number?
A composite number is a positive integer. which is not prime (i.e., which has factors other than 1 and itself)
Step-by-step explanation:
well it represents
-1 < X ≥ 3
so answer is 0 1 2 3
