Answer:
A
Step-by-step explanation:
Antonia: 150 x 12 + 4,500 = 6,300
Cal: 250 x 12 + 3,400 = 6,400
Answer:
The function notation is given as:
$6 + $30 × x
f(x) = $6 + 30x
The dog walker charges $28.50
Step-by-step explanation:
Let the hourly rate be represented by x
A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30.
The function notation is given as:
$6 + $30 × x
F(x) = $6 + 30x
How much does the dog walker charge for a 45 minute walk?
We have to convert 45 minutes to 1 hour
60 minutes = 1 hour
45 minutes = x
x = 45/60
x = 3/4(hour)
Putting that in the function notation:
f(x) = $6 + 30x
x = 3/4
$6 + 30(3/4)
$6 + $22.5
= $28.50
Therefore, the dog walker charges $28.50
F(x) = x/4
so
f(-8) = -8/4 = -2
answer
f(-8) = -2
16.92 × 8.4 = 142.128
This is called the product
Change in value = 87 - 42 = 45
percentage change = 45/42 x 100 = 107%
