Answer:
and 
Step-by-step explanation:
Given:
.......................... equation i
........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have
Add 
to both sides , we have
subtract 3 from both sides , we have
divide both sides by 4 , then
substitute into equation i to get the value of y , that is
Therefore :
and
Alright, so [-2.99] is -2.99, and [2.99] is 2.99, so -2.99+2.99=0
Yes it can, be cause 13 is greater than 12
subtract
13-12=1 so
7 and 13/12=7+1 and 1/12=8 and 1/12
87=(T1+T2+T3+T4+T+T6)/6
87=(93+87+82+86+x+(x-4))/6
87*6=93+87+82+86+2x-4
87*6=344+2x
178=2x
89=x implies 85, 89
