Answer:
(a) x = (3 -ln(3))/5 ≈ 0.819722457734
(b) y = 10
Step-by-step explanation:
(a) Taking the natural log of both sides, we have ...
2x +1 = ln(3) +4 -3x
5x = ln(3) +3 . . . . . . . . add 3x-1
x = (ln(3) +3)/5 ≈ 0.820

(b) Assuming "lg" means "log", the logarithm to base 10, we have ...
log(y -6) +log(y +15) = 2
(y -6)(y +15) = 100 . . . . . . . taking antilogs
y^2 -9x -190 = 0 . . . . . . . . eliminate parentheses, subtract 100
(y -19)(y +10) = 0 . . . . . . . . factor
The values of y that make these factors zero are -19 and 10. We know from the first term that (y-6) > 0, so y > 6. That means y = -19 is an extraneous solution.
The solution is ...
y = 10

When solving equations using a graphing calculator, it often works well to define a function f(x) such that the solution is f(x) = 0, the x-intercept(s). That form is easily obtained by subtracting the right side of the equation from both sides of the equation. In part (a) here, that is ...
f(x) = e^(2x+1) -3e^(4-3x)
Answer:
Step-by-step explanation:
e^(2x + 1) = 3e^(4 - 3x)
e^(2x + 1) = e^3(4- 3x)
lne^ (2x + 1) =ln e^3(4- 3x)
2x + 1 = 3*(4 - 3x)
2x + 1 = 12 - 9x
11x + 1 = 12
11x = 12 - 1
11x = 11
x = 1

I've never worked with binary logs but I'll give this my best shot. If someone comes along and gives you a different answer, use it.
lg(y-6) + lg(y + 15) = 2
lg (y - 6)(y + 15) = 2
inverse (y - 6)(y + 15) = 2^2
(y - 6)(y + 15) = 4
y^2 + 9y - 90 - 4 = 0
y^2 + 9y - 94 = 0
y = 6.19
y = -15,19

Savannah drew a map of Texas for her Geography class. According to Savannah’s map scale, one-half inch on the map represents approximately 77.5 kilometers. If the actual distance from Austin to El Paso is approximately 930 kilometers, what is the approximate distance between Austin and El Paso on Savannah’s map?
Answers
Answer:
6 inches
Step-by-step explanation:
First, take the 930 kilometers and divide it by 77.5 kilometers. You will get 12. This means the distance between Austin and El Paso is 12 one half inches. That is equivalent to 6 inches.

What is the measure of angles 1, 2, and 3?
Answers
Answer:
1= 70
2= 65
3= 95
For 1, just solve 180-(65+45) and then for 2, subtract #1 and 45 from 180. Then just solve for #3 by using 180-(#2+20)
2 is 65° because a line is equal to 180° as well so since 1 is 70 and being given 45, we add them to get 115 and 180-115 is 65.
3 is 95°because a triangle is equal to 180° so since 2 is 65 and being given 20°, you add those to get 85° and 180-85 is 95.

General Formulas and Concepts:
Alg II
- Solving radical equations
Step-by-Step explanation:
When you solve a radical equation, you always have to check for extraneous solutions. This is because the solution x we found while solving the equation may not work in the original problem.
There are several possible reasons for this. One is the domain of radical functions. We know that on a real number line, we cannot plug in negative numbers under the square root, or we’d get an imaginary number. Another reason is when we square a negative number, it becomes positive.
These are things we must account for when we solve for radical equations. Remember to always check the solutions you found and see if they work. One of them could work, both of them could work, or even neither of them would work.

Evaluate each function.
1) f(x) = x2 + 4x; Find f(-7)
Answers
Answer:
The answer is -77
Step-by-step explanation:
Ok, so assuming by x2 you mean x squared, I will solve this. So basically when you have a function, f(-7) would mean that you would have to replace all the x's in the equation with -7. So let's write that out. that would be f(-7) = -7^2 + (-7*4). So now according to PEMDAS, you would solve the exponent first, and -7^2 is equal to -49, because when you solve it you would do -(7^2), which is -(49), which is then -49. So now you have f(-7)= -49+ (4*-7). Solving for (4*-7), you get -28. This leaves you with -49 + (-28), which is -49 - 28. Simplifying that, you get the answer, which is -77.

Vertical Angles Theorem
∠5 ≅ ∠13
∠10 ≅ ∠14
Answers
Answer:
got them all correct
Step-by-step explanation:
Congruent angles within two parallel lines are either vertical angles or corresponding angles. The reason for the congruence of the given angles are:
[tex]\angle 13[/tex] and [tex]\angle 16[/tex]
Reason: vertical angle theorem
[tex]\angle 1[/tex] and [tex]\angle 5[/tex]
Reason: corresponding angles for parallel lines p and q, cut by transversal r
[tex]\angle 5[/tex] and [tex]\angle 13[/tex]
Reason: corresponding angles for parallel lines r and s, cut by transversal q
[tex]\angle 10[/tex] and [tex]\angle 14[/tex]
Reason: corresponding angles for parallel lines p and q, cut by transversal s
From the given figure, we have the following:
Line p || Line q --- > This means that lines p and q are parallel
Line r || Line s --- > This means that lines r and s are parallel
From the attached figure, [tex]\angle 13[/tex] and [tex]\angle 16[/tex] are vertical angles.
Vertical angle theorem states that vertical angles are congruent.
So, the reason for the congruence of [tex]\angle 13[/tex] and [tex]\angle 16[/tex] is vertical angle theorem
[tex]\angle 1[/tex] and [tex]\angle 5[/tex] are corresponding angles of lines p and q, where line r passes through lines p and q.
Corresponding angles are congruent.
So, the reason for the congruence of [tex]\angle 1[/tex] and [tex]\angle 5[/tex] is that corresponding angles for parallel lines p and q, cut by transversal r
[tex]\angle 5[/tex] and [tex]\angle 13[/tex] are corresponding angles of lines r and s, where line q passes through lines r and s
So, the reason for the congruence of [tex]\angle 5[/tex] and [tex]\angle 13[/tex] is that corresponding angles for parallel lines r and s, cut by transversal q
[tex]\angle 10[/tex] and [tex]\angle 14[/tex] are corresponding angles of lines p and q, where line s passes through lines p and q
So, the reason for the congruence of [tex]\angle 10[/tex] and [tex]\angle 14[/tex] is that corresponding angles for parallel lines p and q, cut by transversal s
