9=ln(x+7) | Solve for x
Answers
Answer 1
Answer:
remember that ln=
and
means 
convert
ln(x+7)=9 means
e^(9)=x+7
minus 7 from both sides
e^9-7=x
use calculator to evaluate
8096.08=x aprox

Answer:
Step-by-step explanation:
As given in the question
If e varies jointly with f and g.
i.e
e = kfg
Where k is the constant of variation.
As
When e = 4, f = 2, and g = 8
Put in the above
4 = k × 2 × 8
4 = 16k
in joint variation, the equation of variation holds the form
e=k*fg, where k is the constant of variation. you can see how if either f or g increases, e increases as well, making e vary jointly with f and g. we are given the numbers e=4, f=2, and g=8, so when we input those into the general equations,
4=k*2*8,
k=1/4
e=k*fg, where k is the constant of variation. you can see how if either f or g increases, e increases as well, making e vary jointly with f and g. we are given the numbers e=4, f=2, and g=8, so when we input those into the general equations,
4=k*2*8,

Blue- f(4) = 2(4) - 5 = 3
Teal- f(4) = 4
Yellow- f(4) = 1/2(4) + 1 = 3
Red- f(4) = 2(4) - 5 = -1
