36
3x = 2(90 - x)
3x = 180 -2x
5x = 180
x = 36
Answer:
1. observational study
2.survay
3.experiment
Step-by-step explanation:
Given:
The set of ordered pairs in the options.
To find:
The set of ordered pairs which does not represent a function.
Solution:
A set of ordered pairs represents a function if their exist a unique y-value for each x-value.
In option 3, the given set of ordered pair is:
{(−3,−3),(4,1),(−3,3),(2,2)}
Here, we have to y-values -3 and 3 for x=-3. It means the y-value is not unique for x=-3. So, this set of ordered pairs is not a function.
In option 1, 2 and 4, all the x-coordinates are different. It means their exist a unique y-value for each x-value. So, the set of ordered pairs in options 1, 2 and 4 represent a function.
Therefore, the correct opting is 3.
Answer:
Answer:
4.8 gigabytes
Step-by-step explanation:
Let the number of gigabytes of data = x
Xavier pays a flat cost of $44 per month and $3 per gigabyte. He wants to keep his bill at $58.40 per month.
The above expression above is represented by the equation:
$44 + $3 × x = $58.40
44 + 3x = 58.40
Solving for x
Subtract 44 from both sides
44 - 44 + 3x = 58.40 - 44
3x = 14.4
x = 14.4/3
x = 4.8 gigabytes
Step-by-step explanation:
The y-intercept is (0, 2), because it's the spot where the line crosses the y-axis. The other point showed on the graph is the x-intercept..
