Molly and Nancy disagree about the value of the expression 2+3×4. Molly thinks it is 20 and Nancy thinks it is 14.how could
2 answers:
Molly- 2+3 equals 5 then she times that by 4 which gets 20 but Nancy used PEMDAS and did 4x3 then added 2 which gets 14. Nancy is correct
Molly : she calculated 2 + 3 x 4.....and she got 20......so she basically added 2 + 3 (which equals 5), then multiplied by 4...giving her 20.
Nancy : she calculated 2 + 3 x 4...and she got 14...so she basically multiplied the 3 x 4 (which is 12) and added the 2.
Nancy is correct because in PEMDAS (the order of operations) multiplication comes before addition

Yes he is right because if u have
-6 -(-4) u would multiply the 2 signs the - and the -4 and u would get +4
then ur equation becomes -6+4 = -2
Answer:
y>=1*x+2
Step-by-step explanation:
y>=k*x+n
we know that 2=k+n and 0=-2k+n
so 4=2k+n and 0=-2k+n
now 4=2n so n=2
now k=1
so y>=1*x+2
