Well the answer is 2,169,490, but what’s the whole question
Answer:
x = 16
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
a) linear. Cost per minute is a constant.
b) f(x) = 40 -0.15x
d) f(100) = 25. The remaining value is $25 after using 100 minutes.
Step-by-step explanation:
a) Since the cost per minute is a constant, the remaining dollar value of the phone decreases by the same amount for each minute used. The cost as a function of minutes used is a linear function with a constant rate of change.
__
b) The value starts at $40 and decreases by $0.15 for each increment of x (minutes used). The function can be written as ...
f(x) = 40 -0.15x
__
d) Put 100 where x is in the function definition and do the arithmetic.
f(100) = 40 -0.15×100 = 40 -15
f(100) = 25
According to the variable and function definitions, x=100 means 100 minutes have been used; f(x) = 25 means the remaining value of the phone is 25 dollars.
f(100) = 25 means the phone's remaining value is $25 when 100 minutes have been used.
Answer:
Answer is 1/2 or .5.
Step-by-step explanation:
Out of a die, numbers 2, 4, and 6 are even. So 3/6 numbers on a dice are even. Reduced, the answer is 1/2.
