ANSWER
c. Domain: [0,18]
Range: [0,360]
EXPLANATION
The domain refers to the values of x for which the function is defined.
The given straight line graph is defined for x=0 to x=18.
Hence the domain is [0,18]
The range refers to the values of y for which x is defined.
The graph is defined for y=0 to y=360.
The range is [0,360]
Answer:
We just figure out what 3/4 of 20 is and it is 15 so 15 pens!
Step-by-step explanation:
Sum of interior angles = 180(n - 2)
in this case n = 5 so 180(5-2) = 180(3) = 540
120 + 120 + x + x + x = 540
3x + 240 = 540
3x = 300
x = 100
answer
B) 100
Answer:
85
Step-by-step explanation:
The discount is original price times the percent off
The sale price is the original price minus the discount
original price - original price * 20 % = 68
Factor out the original price and change the percent to a decimal
original price ( 1 - .20) = 68
original price ( .80) = 68
Divide each side by .80
original price = 68/.80
original price = 85
