Question

1. Find the exact solution to the equation. 6-log8(x+7) = 5 a) x = 15 b) x = 1 c) x = 2 d) x = -12. Find the exact solution to the equation. (5 points)one hundred times one fifth to the power of quantity x divided by four equals four.a) x = one divided by twob) x = 8c) x = 2d) x = 93. Determine the function which corresponds to the given graph. a natural logarithmic function crossing the x axis at negative four and going through the point 1,2.The asymptote is x = -5

Answer 1

`\begin{gathered} 6-\log _9(x+10)=5 \\ -\log _9(x+10)=5-6 \\ -\log _9(x+10)=-1 \\ \log _9(x+10)=1 \\ x+10=9^1 \\ x+10=9 \\ x=9-10 \\ x=-1 \end{gathered}`
