See the picture attached to better understand the problem

we know that
If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
so
jl*jk=jn*jm------> jn=jl*jk/jm

we have
jk=8,lk=4 and jm=6
jl=8+4----> 12

jn=jl*jk/jm-----> jn=12*8/6----> jn=16

the answer is
jn=16

Solve this equation for x. Round your answer to the nearest hundredth. 1 = In(x + 4)

KATRIN_1 [288]

Answer:

x ≈ - 1.28

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇔ x = $b^{n}$

Given

ln(x + 4) = 1 , then

x + 4 = $e^{1}$ ( subtract 4 from both sides )

x = $e^{1}$ - 4 = - 1.28 ( to the nearest hundredth )

If f(x)=7-3x and g(x)=3x-7, what is the value of f(1)-g(1)?

postnew [5]

Substitute 1 for x in each of your equations.

f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4

Then subtract g(x) from f(x):
3-(-4)
=7
