Please help me i beg of u due today my teacher be buggin
mart [117]

Answer:

1) 35+5w=110

2) the starting heart rate is 73 beats per minute

3)B

4) 6mins

Step-by-step explanation:

1) since she deposits 5 dollars each week we can multiply 5 and w to find out how much money hes depositing after all the weeks are done. We need to add that with 35 to get the TOTAL money in the bank account.

2) 73 is the y intercept. The y intercept is the number when "x" is 0. So when hes just starting out/not excersizing his heart beats 73 beats per min.

3) we know that 10% of her tips is given back to her hence x(number of tips) is multiplied by 0.1, and added to 50 to find the total amount of money she receives

4) 6 mins for 1 order
