Answer:
Step-by-step explanation:
The interior angles of a heptagon add up to 5*180 = 900
So
x + 143 + 116 + 135 + 135 + 116 + 155 = 900 Add up the known angles
x + 800 = 900 Subtract 800 from both sides
x + 800 - 800 = 900 - 800 Combine
x = 100
Any point in that shaded area is a solution
(0,0) is a solution
(-1,-1) is a solution
(-3,3) is a solution
etc
Answer:
3
Step-by-step explanation:
Answer:
The answer is 70.
Step-by-step explanation:
You replace x with -5.
So you get:
K(-5) = 6(-5)+100
6(-5)= -30
-30+100=70
Therefore K(-5)=70
