Answer:
The equation has an Inifinite amount of solutions
Step-by-step explanation:
2 ( 3g + 2 ) = 1/2 ( 12g + 8 )
First use the distributive property of multiplication -
6g + 4 = 6g + 4
6g cancels out from both sides of the equation -
4 = 4
When both sides of an equation are the same there is an infinite amount of solutions.
Hope this helped! :)
Answer:C
Step-by-step explanation:
I seraph it up
Slope of line l (m1)=5
Slope of line w(m2)=-1/5
Since,m1×m2=-1 , line 'l' and 'w' are perpendicular.
Since line 'k' doesn't intersect line 'l' ,they must be parallel b'coz they are in the same plane as well.
Here, 'l' is perpendicular to 'w' and parallel to 'k'....so w and k must be perpendicular to each other.
It can be proven:
Since l and k are parallel, their slopes are equal.
So, slope of k (m3)=5
Since m3×m2=-1 ,w and k are perpendicular.
Hence, angle between w and k is 90°
