20 bags of popcorn they were sharing
" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function ⇒ D
Step-by-step explanation:
The form of the linear function is f(x) = mx + b, where
- m is the slope (rate of change) of the function
- b is the y-intercept (initial amount) of the function
∵ f(x) = 37 x + 20 models the total cost for Rachel to be a member
at a gym for x months
∵ f(x) = m x + b
∴ m = 37 and b = 20
∵ m represents the rate of change
- That means she must to pay 37 per month for x months
∴ Rachel must pay $37 per month to use the gym
∵ b represents the initial amount
- That means she pays a fixed amount one time
∴ Rachel must pay a $20 membership fee to join the gym
" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function

Answer:

Step-by-step explanation:
(18)
Since BD is an angle bisector , then
∠ DBC = ∠ ABD = 57°
∠ ABC = ∠ ABD + ∠ DBC = 57° + 57° = 114°
(19)
Since BD is an angle bisector , then ∠ ABD = ∠DBC
∠ ABC = 110° , so
∠ ABD = ∠ DBC = 110° ÷ 2 = 55°

Start by subtracting 2 from both side which gives you [-3x<9] then divide by -3 which gets you [x<-3] so the answer is B
