Answer:
tangent: y- 
= -4(x - 
)
Step-by-step explanation:
differentiating
isolating y' to one side and simplifying
when x = 
,
y' = 
y' = 
tangent: y- = -4(x - )

Answer:
25 minutes left for reading.
Step-by-step explanation:
(1/3)*(1 hour)= 20 minutes
(1/4)*(1 hour)=15 minutes
Add the two answers: 35 minutes total spent on her phone and brushing her teeth, leaving 25 minutes to read.
Remember there are 3ft in a yard and 12in. in a foot.
To convert 5.5ft to yd, divide by 3.
To convert 2.5yd to ft, multiply by 3 to get 7.5ft.
To convert 7.5 ft to in, multiply by 12.
Just remember when converting to a larger quantity (yards, for example) to a small (feet, for example), you multiply, and from smaller quantity to larger, divide.
