Answer:
Step-by-step explanation:
Donald's score, rewritten as a decimal fraction, is 0.625.
Karen's, similarly rewritten, is 0,8.
Because both of these scores are greater than 0.6, both students passed.
15 - -6 = 21. 21 points!
m(x)= 0 when X= 3
2*3=6
6-6=0
For (2x-6)
3-4=-1
So -1*0=0
it can also be look at like this (0,-1)
