Answer:

Step-by-step explanation:

7x - 1 + 3x - 9 = 180

10x - 10 = 180

10x = 190

x = 19

7(19) - 1 = 133 - 1 = 132

3(19) - 9 = 57 - 9 = 46

Find the domain of the function (f/g)(x) where f(x)=√x+1, g(x)=√x-9

nadya68 [22]

Answer:

4x + 9. Given f(x) = 2x + 3 and g(x) = –x2 + 5, find (g o g)(x). (g o g)(x) = g(g(x)) ... Given f (x) = sqrt(x) and g(x) = x – 2, find the domains of ( f o g)(x) and (g o f )(x). Since f (x) involves a square root, the inputs have to be non-negative. ... Given h(x) = (x + 1)2 + 2(x + 1) – 3, determine two functions f (x) and g(x
