Hello,
y=2x+5
==========
(y-5)=2(x-0)
Answer:
$3
Step-by-step explanation:
23-17=6
6/2=3
To check:
6+17=23
Answer:
5/32
Step-by-step explanation:
If a coin if flipped five times with four heads, then it has exactly one tail. The number of way to arrange four heads and one tail are as follows:
T H H H H
H T H H H
H H T H H
H H H T H
H H H H T
Essentially, there are five way because there are five "positions" where the tail could be.
Then, you need to find the total amount of possibilities for flipping a coin five times. Every time you flip it, there are two possibilities- heads and tails. Therefore, for five flips, the total amount of possibilities is
2x2x2x2x2 = 32
You know that
probability= # of desired outcome
----------------------------------
# of total outcomes
So the probablity is 5/32.
Answer:
Step-by-step explanation:
We can add the two equations to eliminate 
and solve for 
.
Now, we can find for by using substitution:
