Answer:
80 degrees
Step-by-step explanation:
Sum of the interior angles of a triangle = 180
a + 50 + 50 = 180
a = 80

Answer:
y = 4x - 9
Step-by-step explanation:
Take 2 points:
(0,-9) and (4,7)
Find the slope:
(7 - (-9))/(4 - 0)
16/4 = 4
so we have y = 4x + b
Now find b:
Insert a point for y and x:
7 = 4(4) + b
7 = 16 + b
b = -9
y = 4x - 9
The answer is D
Because in dividing fraction the second fraction has to be reversed so for example: 6/5 is suppose to be 5/6
So in this case the answer is D
