Answer
16
Explanation
Factors are number that you can multiply to get another number. A number between 1 and 20 that has many factors are 12, 16, 18..
We can find the factors of this numbers and identify the one with five factors.
12→1,2,3,4,6,and 12
16→1,2,4,8,and 16
18→1,2,3,6,9,and 18
We find the 16 has exactly 5 factors.

D: {0, 1, 2, 3}
R: {−3, −2, 2, 5}
The relation is a function.
That's the answer.
Answer:
Un ejemplo de una recta numérica es lo que un estudiante de matemáticas puede usar para encontrar la respuesta a las preguntas de suma y resta. Una línea recta, teóricamente que se extiende hasta el infinito en direcciones tanto positivas como negativas desde cero, que muestra el orden relativo de los números reales.
explanation:
what is the number line
An example of a number line is what a math student can use to find the answer to addition and subtraction questions. A straight line, theoretically extending to infinity in both positive and negative directions from zero, that shows the relative order of the real numbers.
So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
