Number (x) 1 -1 2 -2
Fourth power of the number (y) 1 1 16 16
(a) Does the table represent y as a function of x?
From the table we can see that every x value has a corresponding y value
The x values are not repeating. So It is a function.
If we graph the table then it will pass vertical line test.
B: The total cost f(x), in dollars, for renting a truck for x hours is shown below: f(x) = 17x + 50 What is the value of f(30) and what does f(30) represent?
Total cost f(x) = 17x + 50
To find f(30), we plug in 30 for x
The rent of the truck for 30 hours is $560
For this case we have that by definition, an equation of the second degree is given by:
We have the following equation:
Then, according to the definition above, we have to:
Thus, b equals 5.
Answer:
Option C
Answer:
see below
Step-by-step explanation:
The square root function produces a non-negative output for a non-negative input. When its output is negated, it produces a non-positive output for a non-negative input.
The input (domain) is from 0 to infinity: [0, ∞).
The output (range) is from negative infinity to zero: (-∞, 0].
____
A graph of the function is included for your convenience.
Answer:
The answer to your question is ∠ABE = 46
Step-by-step explanation:
Data
BE is a bisector of ∠ABE
∠ABE = 2x + 20
∠EBC = 4x - 6
∠ABE = ?
Process
1.- Bisector is a line that divides an angle into two equal angles.
So
∠ ABE = ∠EBC
2.- Substitution
2x + 20 = 4x - 6
3.- Solve for x
2x - 4x = -6 - 20
- 2x = -26
x = -26/-2
x = 13
4.- Find the measure of ∠ABE
∠ABE = 2(13) + 20
∠ABE = 26 + 20
∠ABE = 46
