Step-by-step explanation:
This is confusing, what does g(x) equal? There's a bunch of random numbers there. I'll just assume.
They stated that f(x) needs to exceed g(x), so make an inequality plugging in the values

You see, function f(x) needs to be higher than function g(x)
Subtract 7x from both sides to get:

Divide both sides by -4, when you divide by a negative number the signs switch so it is now less than.
x < -1.5
And obviously that's not an answer up there, so you made a mistake stating the values of the functions
Answer:
27.23
Step-by-step explanation:
60.50 divided by .45
9/100 is less because if we multiply 7/10 by 10 (to get an equivalent fraction with a denominator the same as the other fraction [100]) we get 70/100, which is way more than 9/100.
So, 7/10 is greater than 9/100
Hope this helps!
