Answer:
(a)
Step-by-step explanation:
using the following
The sum of the 3 angles in a triangle = 180°
The sum of the angles on a straight angle = 180°
To find x subtract the sum of the 2 given angles in the triangle from 180
x = 180 - (56 + 38) = 180 - 94 = 86 ( sum of angles in a triangle )
To find z, subtract x from 180
z = 180 - 86 = 94 ( angles on a straight angle )
To find y subtract the sum of the 2 angles from 180
y = 180 - (94 + 19) = 180 - 113 = 67
x = 86, y = 67 and z = 94
Answer:
-6/5
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
Plug in
Slope = (4 + 2)/(-2 - 3)
Slope = -6/5

Answer:
When A is positive there is a minimum vertex.
Step-by-step explanation:
When a parabola is positive the opening goes upwards. When a parabola is negative it goes downwards. The negative sign on the A coefficient means that you reflect your equation across the x-axis
