Answer:
option 2
f(3+4)
Step-by-step explanation:
To understand this problem, what we can do is solve and compare with the results they give us.
f(x)=a^x f(3) * f(4)
f(3) = a^(3) f(4) = a^(4)
we replace
f(3) * f(4) = a^3 * a^4
as they are powers of the same base
f(3) * f(4) = a^(3+4)
f(3) * f(4) = a^7
Now let's do it with the options they give us
1. f(3^4) f(x)=a^x
3^4 = 81 x = 81
f(81) = a^81 wrong option
2. f(3+4) f(x)=a^x
3+4 = 7 x = 7
f(7) = a^7
correct option
3. f(3*4) f(x)=a^x
3*4 = 12 x = 12
f(12) = a^12 wrong option

Step-by-step explanation:
I’m just gonna go with it’s 2 separate math questions
so for:2y+7x=-5
(In my answers If there is a slash between two numbers it means it is a fraction)
X= - 2y/7-5/7
Y= - 7x/2-5/2
For 5y-7x=12
X= 5y/7-12/7
Y=7x/5+12/5
Hope I could help
