Answer: -(1 + 25/54)
Step-by-step explanation:
First replace each “x” with 7 on both sides:
f(7) = -12 * 7 + 5 and g(7) = 7^2 + 5
Simplify:
f(7) = -79 and g(7) = 54
-79/54 simplified becomes -(1 + 25/54), or -(1 25/54)
Answer:
-79/54
Step-by-step explanation:
first replace x with 7 so do -84+5=-79, you will then have -79/g(7)
To find what x equals in g(7) we can replace the the domain with 7 in the equation for g(x) because we have g(7) so we would have 7^2+5 which is 54
then we would have -79/54
