Function notation replaces the 'y' with a letter, usually 'f' and then puts the variable in parenthesis.
f(x) = 3x
Other equivalent examples would be:
g(x) = 3x
f(z) = 3z
h(a) = 3a
All of these represent the same function, just written in different forms of function notation. The variable can be represented as any letter and the function name can be different letters as well.
Answer: y = 3
<u>Explanation:</u>
Parallel to the x-axis means slope (m) = 0
Input the given point (1, 3) and the slope into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - 3 = 0(x - 1)
y - 3 = 0
y = 3
2 15 is the probability? I don't see that making sense
The problem does not clearly give us the distance from Buffalo to Chicago, so let this be x (in mile) just so I can show you how the total cost is solved.
The total cost is equal to the sum of the rental fee plus the cost of the additional fee per mile which is equal to 1.50x, and also of the cost of the gasoline which is equal to (x/16)(2.15). Thus, the final answer should be expressed as,
total cost = 29.95 + 1.5x + 2.15x/16
When the distance is available, this should be easily substituted in the equation above.
Answer:
3125
Step-by-step explanation:
If there are 5 vowels: A, E, I, O, U
and each obe can be used more than once, then you have 5 options for each of the 5 slots
<u> </u><u> </u><u> </u><u> </u>×<u> </u><u> </u><u> </u><u> </u>×<u> </u><u> </u><u> </u><u> </u>×<u> </u><u> </u><u> </u><u> </u>×<u> </u><u> </u><u> </u><u> </u> = <u>5</u>×<u>5</u>×<u>5</u>×<u>5</u>×<u>5</u> = 3125 possibilities
hope this helps!
