Perform the indicated operation.
f (x) = x2 − 1 g(x) = 3x + 4 Find f (9) − g(9)

f(9)=17//g(9)=31

Step-by-step explanation:

substitute- (9)2-1= 18-1=17

substitute and solve- 3(9)+4=27+4=31

Hope this helps

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
