Answer:
B
Step-by-step explanation:
This is easier to follow if you write it out the long way.
g(x) = (x + 3)/x
g(f(x)) = (f(x) + 3)/f(x)
g(x^2 - 7) = (x^2 + 7 + 3)/(x^2 + 7)
g(x^2 - 7) = (x^2 +10 ) / (x^2 + 7)
g(-5) = ( (-5)^2 + 10) / ( (-5)^2 + 7)
g(-5) = ( 25 + 10) / (25 + 7)
g(-5) = 35/32
Answer:
300
Step-by-step explanation:
![\frac{Part}{Whole} = \frac{Percent}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BPart%7D%7BWhole%7D%20%3D%20%5Cfrac%7BPercent%7D%7B100%7D)
![\frac{210}{x} =\frac{70}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B210%7D%7Bx%7D%20%3D%5Cfrac%7B70%7D%7B100%7D)
210(100) divided by 70 = 300
