Answer:
f(x) = 2x+5
f(3) = 2(3) +5 = 6+5 =11
There fore f(3) =11
The first function is correct
Step-by-step explanation:
Given f(2) =9 and given functions are f(x) = 2x+5 and f(x) =4x+5
The fsecond function is not satisfies f(2)=9 because
f(x) = 4x+5
f(2) = 4(2)+5 = 13≠9
f(x) = 2x+5
f(2) = 2(2)+5=9
therefore first function is satifies
f(x) = 2x+5
f(3) = 2(3) +5 = 6+5 =11
There fore f(3) =11

Answer:
50 degrees
Step-by-step explanation:
The sum of the interior angles of a triangle is 180. We can find the missing angle of the triangle by subtracting out the two measurement of the triangle that we know from 180.
180 - 31 -19 = 130
This angle would be the alternate exterior angel to the parallel line QP. That angle is supplement to the angle that you are looking for. <QTP would be 50 (180 -130)
