Answer:
x = 2.564 ( to 3 dec. places )
Step-by-step explanation:
Using the rule of logarithms
log
⇔ n logx
Given
= 62 ( take the ln of both sides )
ln
= ln 62, that is
x ln5 = ln 62 ( divide both sides by ln 5 )
x =
≈ 2.564
Answer:
n=-10/3
Step-by-step explanation:
"Twice the difference of a number n and seven is equal to four less than the product of five and the number n" translates into 2(n-7) = 5n - 4. To solve, isolate the variable n.
2(n-7) = 5n - 4
2n - 14 = 5n - 4
2n - 10 = 5n
-10 = 3n
-10/3 = n
I have attached the graph so you can compare but it is graph C.
Hope that helps.
