Answer:
250; 
Step-by-step explanation:
a. 15 minutes passed, so there would be 250 people who came in
b. You would create a formula, where t = time after 8:15 (in minutes), while p = people who are at the parade
, which equals 
Answer:
4 1/6
Step-by-step explanation:
A function is for every input, there is 1 output
aka
x never repeats with a different y
A. x doesn't repeat, it's a function
B. -8 repeats with 34 and 40, this is not a funciton (this is the answer0
C. x doesn't repeat, it's a function
D. x doesn't repeat, it's a function
answer is B
Answer:
4n + 8 = -48
n = -14
Step-by-step explanation:
Using key words from the problem, you can set up an equation with the proper operations to solve for the variable. Product = multiplication, so the 'product of 4 and a number' = 4n. Increased = addition, so increased by 8 = 4n + 8. The word 'is' means equal to, so:
4n + 8 = -48
In order to solve for 'n', you use inverse (opposite) operations and whatever you do to one side of the equation, you do to the other:
Subtract 8: 4n + 8 - 8 = -48 - 8 or 4n = -56
Divide 4: 4n/4 = -56/4
Solve for 'n': n = -14
