Answer:
225
Step-by-step explanation:
360 - 135 = 225
To find the intersection points, you take x^2 - 4x + 9 = -2x + 17
This gives x^2 - 2x - 8 = 0,
which factorises to (x - 4)(x + 2) = 0, giving the solutions x = 4 or x = -2
From the graph, we can see that x is positive, meaning x = 4, so a = 4.
Substituting x = 4 into y = -2x + 17, we get y = -2(4) + 17 = 9, so b = 9.
a + b = 4 + 9 = 13. The answer is B.
All you have to do is try both of the equations by filling in the variables with the choices.
-5 > -3 (2) + 3
-5 > -5 + 3
-5 > -2
-5 > (2) + 2
-5 > 4
So, this does not work.
--------------------------------------------
5 > -3 (-2) + 3
5 > 5 + 3
5 > 8
5 > (-2) + 2
5 > 0
So, this does not work.
-------------------------------------------
5 > -3 (2) + 3
5 > -5 + 3
5 > -2
5 > 2 + 2
5 > 4
So, this works.
-----------------------------
-5 > -3 (-2) + 3
-5 > 5 + 3
-5 > 8
-5 > (-2) + 2
-5 > 0
So, this does not work.
The answer would be C.
I hope this helps!
Answer: 
Step-by-step explanation:
g°h indicates that you must plug the function h(x) into the function g(x) as you can see below:
Now you must simplify by adding like terms, as following:
By definition you have that:
Theen you must solve for x:
Therefore, the domain is:
{
∈R:}
Then the answer is
