Answer:
$2.55 per person
Step-by-step explanation:
Byron plus his 3 friends = 4 friends total. If there are 8 1/2 of candy total and there are 4 people, you would need to divide 8 1/2 by 4 which would give you 2.125. From there, you would need to multiply that by $1.20, the amount per pound which would give you $2.55. So, each person paid $2.55 for candy.
To do this, we have to multiply the 7 feet diameter by pi to get the circumference because the formula for circumference is

, or circumference = pi times diameter. 7 x 3.14 (pi rounded) = 21.98
Answer: 21.98 feet
Answer:
Value of b is all the numbers.
All the numbers will satisfy the value of b.
Step-by-step explanation:
4b + 21 = b + 3 ( b + 7 )
4b + 21 = b + 3b + 21
4b + 21 = 4b + 21

restrict the domains of quadratic functions and absolute value functions, because these functions are

functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are

functions, so their domains

to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
