Answer:
2.f(x)=2^4x
Step-by-step explanation:
16^x
We can rewrite 16 as 2^4
2^4^x
We know that a^b^c is equal to a^ (b*c)
so 2^(4*x)
2^(4x)
76 ÷4=19
76/4+10=x
19+10=x
29=x
There is 29 questions on the test, and he got 19 correct. (65.5%)
good luck
3 (x-5) = 18
3x - 15 = 18
3x = 18 + 15
= 33
x = 11
I hope this helped! :)
Answer:
x=-6 y=7
