Answer:
x = 18
Step-by-step explanation:
When two parallel lines are intersected by a transversal, then same-side exterior angles are supplementary, meaning their angle measures add up 180 degrees. Applying this knowledge here, one can state that;
( 6x - 3 ) + 75 = 180
Simplify,
6x - 3 + 75 = 180
6x + 72 = 180
Inverse operations,
6x + 72 = 180
-72 -72
6x = 108
/6 /6
x = 18
To find the range we need to find the vertex of the parabola which is at (-b/2a , y)
-b/2a would be 2/2 = 1 ... so find the y value at x = 1
12 - 2(1) - 15 = 1-17 = -16
So the vertex is at (1,-16)
Since the parabola opens upward from that point the minimum value of the range is y = -16
The range would include the point -16 so it is actually
R = [-16,infinity)
