First we will find the total measure of all the interior angles:
180(n-2)
180(5-2) = 540
So the sum of the interior angles is 540.
Now add all the angles and set them equal to 540
84 + 12x + 92 + 9x - 16 + 13x + 6 = 540
166 + 34x = 540
34x = 374
x = 11
x is 11
Hope this helps :)
The missing angle is 49 :)
The correct answer is 'C'
If X = 2, and Y = 4:
2(2) + 3(4) - 2 - (8 + 1) = 5
4 + 12 - 2 - 9 = 5
16 - 2 - 9 = 5
14 - 9 = 5
= 5
(2) + 3(4) - 9 = 5
2 + 12 - 9 = 5
14 - 9 = 5
= 5
So, your answer would be 'C' X + 3Y - 9
The explicit rule is in the pic
4
1) Examining that graph, we can see that this is a decreasing function, due to the line direction. And that the initial value is the y-intercept.
2) Hence, the initial value is 4. Notice that all values after that goes decreasing for y.
