-5t2 + 40t = 0
5t(-t+ 8) = 0
5t = 0 or t = 8
Answer:
y=1
Step-by-step explanation:
since there is no slope all you have is the y intercept so all you have to put is the y-intercept. That easy!
The answer to this question is 8 for $6
Answer:
The correct answer is t < 60.
Step-by-step explanation:
Lauren wants to keep her cell phone bill below $60 per month.
Lauren's current cellphone plan charges her a fixed price of $30 and per text price for one text is $0.50.
Let Lauren sends t texts in a complete month.
Total money spent on texts in a month is given by $ (0.50 × t)
Therefore Lauren's total spent in a month is given by $ (30 + (0.50 × t)).
But this amount should be under $60 as per as the given problem.
∴ 30 + (0.50 × t) < 60
⇒ (0.50 × t) < 30
⇒ t < 
⇒ t < 60.
So in order to keep her phone monthly bill under $60, Lauren should keep her number of texts below 60.
No, because 30.4+84.6+66=181
the sum of a triangle=180
so they are not similar.
