Answer:
Yes it is.
Step-by-step explanation:
Answer:
m<√-3 OR m<√3i
Step-by-step explanation:
f(x)=x²+2m(x+1)-3
with x<0
b²-4ac<0
(2m)²-4(1×-3)<0
4m²+12<0
4m²<-12
m²<-12/4
m²<-3
m<√-3 OR m<√3i
Step-by-step explanation:
given Tony can type at a constant rate of 110 words every 2 minutes.This means tony can type 55 words in every minute.
A- Tony can type W words in T minutes. W*T=M (M=Minutes Tony typed)
B- Tony can type 1100 words in 20 minutes. as 55*20=1100.
C- Yes, Tony can type the essay. Why: because in this equation w=55 and t=30 minutes so t*w=30*55=1650 so yes, Tony can write the essay.
