For this case, we have that by definition, be given two functions f (x) and g (x). So:
We have:
So:
(f-g) (x) = - 3x-5- (4x-2)
We have to:
Equal signs are added and the same sign is placed while different signs are subtracted and the sign of the greater is placed
Answer:
Option D
Step-by-step explanation:
when intersecting 2 parallel lines by a third line the angles at the intersection points must be the same at both lines. otherwise they are not parallel, or the third one is not a straight line.
the second thing to know : all angles in top of a line (or below a line) are in sum 180 degrees. this is what is needed to e.g. rotate a stick around a point on the line from one side to the other.
knowing all this we then know, that the angle right "under" the (8x -9) degree angle is also 53 degrees (or the angle above the 53 degree angle is (8x - 9) degrees).
and we know then that the sum of both angles is 180 degrees.
(8x - 9) + 53 = 180
8x - 9 = 127
8x = 136
x = 17
First and foremost that is a quadrilateral, because it is a 4-sided figure. If it was a trapezoid it would have only 1 set of parallel lines. So NOT a trapezoid. It is a parallelogram because parallelograms have 2 pair of parallel lines. It is not a rhombus because a rhombus has 4 equal length sides. So it's not a square either. It is not a rectangle either because rectangles have 4 right angles and this one does not. So your choices are 1 and 3.

x = -1
