Initial fee: $25
Per hour fee: $7
Your budget: $60
x = # of hours you can rent the surfboard
$25 + $7x ≤ $60
Subtract $25 from both sides.
$7x ≤ $35
Divide both sides by $7
x ≤ 5
You can rent the surfboard for less than or equal to 5 hours.
Answer:
no, they are not functions
Step-by-step explanation:
this is because a single domain has multiple range.
i.e. domain 2 has ranges 2 and 4
Answer:

Step-by-step explanation:
Given



Required
Determine CD
Since, C is a point on BD, the relationship between the given parameters is;

Substitute the values of BD, BC and CD

Collect Like Terms


Divide both sides by -4


To determine the length of CD;
Substitute 3 for x in 
Hence;

C = 2πr
C = 2π5
C = 2 (3.14) (5)
C = 2 (15.7)
C= 31.4
