If I have an 83% percentage as my grade and I got 90% or 100% in one of my tests, what would be my final grade percentage?

Step-by-step explanation:

if u got 90% then (83+90)/2=86,5%

if u got 100% then (83+100)/2=91,5%

86.5% or 91.5%

Step-by-step explanation:

83+90=173

173÷2=86.5%

OR

83+100=183

183÷2=91.5%

what is the graph

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
