Answer:
<NKM = 77⁰.
Step-by-step explanation:
< KMN = 1/2 * 116 = 58⁰
<JNK = <KMN = 58⁰
Consider the quadrilateral JKMN:
<NJK = 360 - 103 - 58 - 122 = 77⁰
So < JKN = 180 - 58 - 77 = 45⁰.
<NKM = 122-45 = 77⁰.

Step-by-step explanation:
Part 1
<h3>Answer: 13</h3>
---------------------
Explanation:
We'll replace every copy of x with -3. Then use PEMDAS to simplify.
f(x) = -2x+7
f(-3) = -2(-3)+7
f(-3) = 6+7
f(-3) = 13
===========================================================
Part 2
<h3>Answer: -11</h3>
---------------------
Explanation:
We work backwards in a sense compared to what part 1 did. Instead of finding f(x) based on x, we determine what x must be for a given f(x).
We'll replace f(x) with 29 and solve for x like so
f(x) = -2x+7
29 = -2x+7
-2x+7 = 29
-2x = 29-7
-2x = 22
x = 22/(-2)
x = -11
Note how if you replaced x with -11, we'd get,
f(x) = -2x+7
f(-11) = -2(-11)+7
f(-11) = 22+7
f(-11) = 29
which helps confirm we have the correct answer.
Answer:
2%
Step-by-step explanation:
First do 42840/42000 on calculator (or use your brain to solve but i didn't XD)
the answer is 1.02 the percent increase is 2% but 42840 is 102% or 42000
