Answer:
(2,3),(4,3),(-2,-3),(-4,-3)
Step-by-step explanation:
A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).
This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.
The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.
A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.
In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:
(5,1),(5,2),(5,3),(5,4)
Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.

Step-by-step explanation:
First add the 48.75 and 18.30 together.
second multiply 5.50 by 9
she would only earn 49.50 so she won’t be able to buy the bike and helmet
Answer:
x=8
Step-by-step explanation:
Angles 1 and 5 are corresponding angles.
If angles 1 and 5 are congruent, then the lines are parallel.
This means the measurement of angle 1 needs to equal the measurement of angle 5.
This is the equation we must solve:
3x+10=4x+2
Subtract 3x on both sides:
10=1x+2
Subtract 2 on both sides:
8=1x
Use multiplicative identity property:
8=x
So if x=8, then the angles 1 and 5 which are corresponding are congruent.
If corresponding angles are congruent, then the lines are parallel.
