Uma função f é dada por f(x)=ax+b, em que a e b são numeros reais. Se f(-1) = 3 e f(1)= -1, determine o valor de f(3)

Which of the following represents a number squared is equal to twenty more than nine times that number ? a) x squared = 9x + 20 b) x squared = 20x + 9 c) x squared > 9 + 20x d) x squared = 9 + x + 20

Plz hurry evaluate the expression a+b where a=8 and b=19

What is the distance between a and b? round your answer to the nearest tenth. a coordinate plane is shown. point a is located at negative 1, 5, and point b is located at 4, 1. a line segment connects the two points.
