Cai bought popcorn for herself and 2 friends, plus a drink only for herself. The popcorn cost $2 for each person, and
the total cost for Cai's purchase was $7.50. If d is the
cost of a drink, which equation below could be used to
determine the cost of Cai's drink?

b.-4 units

all you   do is count how many times you move

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
