Answer:
x = 8
Step-by-step explanation:
log(5x-4)-log(x+1)=log 4
log [ (5x - 4) / (x+ 1) ] = log 4
[ log (a/b) = loga - logb]
(5x - 4 ) / ( x + 1) = 4
(5x - 4) = 4x + 4
5x - 4x = 4 + 4
Hope it will help :)❤
<u>Step-by-step explanation:</u>
B: 5x + 3
(f+g) (x) = f(x) + g(x) = (2x -6 ) + (3x + 9) = 5x + 3
