if i currently have a 65% in a class and my final is worth 20% of my grade, what do i need to get on my final in order to have a 60% at the end of the class? What do I need to get on my final in order to have a 50%. Thank you

60%= 40

50%=not possible

Step-by-step explanation:

x=grade on final

(65*.8) + (x*.2)=60

52+.2x=60

.2x=8

x=40

(65*.8) + (x*.2)=50

52+.2x=50

.2x=-2

x=-10

not possible

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
