Answer:
This system has no points of intersection.
Step-by-step explanation:
The lines are parallel, so they don't intersect.
I graphed the equations below to show you how they are parallel.
Answer:
107 degrees
Step-by-step explanation:
For an inscribed quadrilateral, the opposite angles are supplementary. Thus, B+D = 180 and you can solve for x.
3x+9+2x-4 = 180
5x = 175
x = 35
Next, plug the x value into angle A.
2(35) + 3 = 73
Angle C is the supplement of this which is 180-73 = 107
Answer:
I think the answer to the first question is "B"
and the second one is "D"
Step-by-step explanation:
Answer: you just have to memorize it it will take time but its better doing it now than in 20 years
Answer:
x=-1/2
Step-by-step explanation:
Solving
2x-1+8=6
2x+7=6
2x=6-7
2x=-1
x=-1/2
Checking
put x=-1/2 in equation
LHS 2(-1/2)-1+8
=-1-1+8
=8-2
=6
RHS =6
