Y=-2x+2
y=x2-2x+4
is the value of x such that when you plug it into both equations, they both produce the same value of y, or the value of x such that
-2x+2=x2-2x+4
solving this equation----------> x2=-2, taking square root of both sides gives x= ±√2i, or the system has no real solutions but has 2 complex solutions. If you graph both functions in the xy-plane, where x, y are real numbers, you' ll see they do not intersect, which implies there is no real number solutions.
This is a classic problem I think that you mean
Answer:
This problem clearly states to use proof by induction, follow the complete answer below.
Step-by-step explanation:
To prove something by induction we have to make a proposition first, in this case:
is divisible by 9
Where is the order of the proposition.
First we have to prove the first few orders, let's just check P(1):
which is clearly divisible by 9
Now let's assume that P(n) is true that means, our original proposition is true. Now let's try to find out whether P(n+1) is true:
The is divisible by 9 because we assumed that " is divisible by 9" was a true proposition. On the other hand has a factor of 9 regardless of n, thus is also divisible by 9 that means that P(n+1) is true and it follows that P(n) must also be true, thus proving our initial statement.

Answer:
3.75 feet.
Step-by-step explanation:
Given:
The volume of a right octagonal prism is 30 cubic feet.
The area of the octagonal base is 8 square feet.
<u>Question asked:</u>
What is the height of the prism ?
<u>Solution:</u>
<em>As we know:</em>
<em />
Therefore, height of the prism is 3.75 feet.
If W=20 put it in for W, Same with all the other letters: so now we have: 20+1/23+1/19+1/28. Now divide: 1/23=.043, 1/19=.053, 1/28=.036... Now add: 20+.043+.053+.036=20.132. The answer is 20.132 :)
