Answer:
Options 1,2,3 are correct statements
The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)
The second values are the range : (-1,1,2,3,4,5)
One input should have only one output for a function.
But -1 input has 2 outputs: -1 and 3.
Thus, it is a relation and not a function.
Hope it helps :)

Answer:
25°C = 77 degree Fahrenheit.
Step-by-step explanation:
In this question we have to write the expression showing the relation between degree Celsius and degree Fahrenheit first.
where C = degree centigrade and F = degree Fahrenheit
Although the question is not clear in the next part but assuming that we have to use this expression to convert 25°C to degree Fahrenheit,
We will plug in the value of C in the expression,
F = 45 + 32
F = 77
Therefore, 25°C = 77 degree Fahrenheit will be the answer.

Answer: x = 16</h3>
============================================
Explanation:
On that diagram, the unmarked angle above the (6x-8) is equal to (5x+12). This is because the unmarked angle and the angle marked with (5x+12) are corresponding angles. Corresponding angles must be congruent if you want line m to be parallel to line n.
From here we add up (5x+12) and (6x-8) and set that sum equal to 180. Solve for x
We get the following:
(5x+12)+(6x-8) = 180
5x+12+6x-8 = 180
(5x+6x)+(12-8) = 180
11x+4 = 180
11x = 180-4
11x = 176
x = 176/11
x = 16
To factor this you need values that add up to 2 and multiply to -15
So you get 5,-3 then you put it into your equation for you b value
X^2+5x-3x-15
Then you can factor by grouping
X(x+5)-3(x+5)
So your factors are
(X+5)(x-3)
