Answer:
C. one line
Step-by-step explanation:
A plane is a two-dimensional figure which is a flat in surface.
Imagine two planes, like you can take two plain plate of the same size, when you intersect one by another by vertical, you will get a line.
Let me show you a figure here.
You can see the green line.
So the two planes insect in exactly one line.
Answer: C. One line
Answer:
Option A is correct.
4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5
Step-by-step explanation:
Given the expression:
If n = -5
then, by substituting in given expression we get;
Option A:
4n + 8
Substitute the value of n = -5 we have;
Option B:
2n + 2
then;
2(-5) + 2 = -10 + 2 = -8
Option C :
then;
Option D:
n + 8
then;
-5 + 8 = 3
Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5
Answer:
2
Step-by-step explanation:
A commutative function means that when you insert one function in space of x in the other function, they will equal x. The equation is f(g(x)) = g(f(x)) = x
So, 2() - 1 =
If you multiply both sides by <em>a</em>, you get 2<em>a</em>() - a = (2x-1)+1
Simplify it 2<em>a</em>() - <em>a</em> = 2x
Add <em>a</em> to both sides 2<em>a</em>() = 2x +<em>a</em>
The two <em>a</em>s on the left cancel out 2(x+1)=2x+<em>a</em>
Distribute the 2 2x+2=2x+<em>a</em>
Then subtract 2x from both sides 2 = <em>a</em>
Therefore, <em>a</em> = 2
Hope this helps!
