Use the rules of logarithms and the rules of exponents.
... ln(ab) = ln(a) + ln(b)
... e^ln(a) = a
... (a^b)·(a^c) = a^(b+c)
_____
1) Use the second rule and take the antilog.
... e^ln(x) = x = e^(5.6 + ln(7.5))
... x = (e^5.6)·(e^ln(7.5)) . . . . . . use the rule of exponents
... x = 7.5·e^5.6 . . . . . . . . . . . . use the second rule of logarithms
... x ≈ 2028.2 . . . . . . . . . . . . . use your calculator (could do this after the 1st step)
2) Similar to the previous problem, except base-10 logs are involved.
... x = 10^(5.6 -log(7.5)) . . . . . take the antilog. Could evaluate now.
... = (1/7.5)·10^5.6 . . . . . . . . . . of course, 10^(-log(7.5)) = 7.5^-1 = 1/7.5
... x ≈ 53,080.96

I think it’s C if you still need an answer but don’t trust me on that
Answer:66
Step-by-step explanation:
Y=mx+b
10=-4*12+b
10=-48+b
b=58
r=-4(-2)+58
r=66
Answer:0.65
Step-by-step explanation:
Firstly, we convert the fractions into decimals:
6/10=0.6
1/5=0.2
1/4=0.25
We then get : 0.6 - 0.2 + 0.25
0.6-0.2=0.4
0.4+0.25=0.65
