Use a calculator to find an approximate solution to the equation. Round any intermediate work and steps to three decimal places.
Mariana [72]
Given;
6Ln (x + 2.8) = 9.6 

We will transpose 6 in the Ln, so that we will leave Ln alone.
Ln (x + 2.8) = 9.6/6 = 1.6 

we divide the 9.6 to 6 and we get 1.6

x + 2.8 = e^1.6 
e^ for the substitution of Ln

x = e^1.6 - 2.8 
insert the e^(1.6) in the calculator and you will get 4.95303242439511 and subtract 2.8 and you will get the answer.

x = 2.153 
2.153 is the final answer in this question.

Explain the difference between the graphs of :
charle [14.2K]

Answer:

The only difference is that for any positive value of 'x' g(X) and h(X) will be same and for any negative value of 'x' g(x) and h(x) will be different.

Step-by-step explanation:

Given

f(x)= |x|

g(x) = |x+5|\\\\h(x)= |x| +5

|x| is modulus of x so modulus makes negative value as psoitive

for example

|3|= 3

|-3|=3

now we will solve for the above

For x=4

g(4)=|4+5|\\=|9|\\=9

and

h(4)=|4| +5\\=4 +5\\=9

Now for x=-4

g(-4)=|-4+5|\\=|1|\\=1

and

h(-4)=|-4| +5\\=4 +5\\=9

so for positive value it is same and for negative value it is different

-2x + 8 = 18 please help. What does x equal
kakasveta [241]

Answer:

x = -5

Step-by-step explanation:

Step 1: Write equation

-2x + 8 = 18

Step 2: Solve for <em>x</em>

  1. Subtract 8 on both sides: -2x = 10
  2. Divide both sides by -2: x = -5

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-2(-5) + 8 = 18

10 + 8 = 18

18 = 18
