Answer:
D. (4, 5)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = x + 1
y = 1/2x + 3
<u>Step 2: Solve for</u><u><em> x</em></u>
- Substitute in <em>y</em>: x + 1 = 1/2x + 3
- Subtract 1/2x on both sides: 1/2x + 1 = 3
- Subtract 1 on both sides: 1/2x = 2
- Divide both sides by 1/2: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x + 1
- Substitute in <em>x</em>: y = 4 + 1
- Add: y = 5
<u>Step 4: Graph</u>
<em>We can confirm our answer.</em>
Answer:
The exact solution is

And the approximation to three decimal places is:
x = 0.363
Step-by-step explanation:
Here we have the equation:

Now we can remember a property of the natural logarithm function:
Ln(a^n) = n*Ln(a)
Now we can apply the Ln( ) function to both sides of that equation to get:

Then we get:

Solving that for x we get:

So the exact solution is:

And the approximation to three decimal places is:
x = 0.363
The equation is 
The solved equation is 11
First, we must add 13 on both sides

The answer to the equation is 
17/30, The peanuts by a dollar per pound (peanuts cost $3, walnuts cost $2), $21, 40072/100 (and I'm not sure how you would reduce it) Good luck!
