When using an indirect proof, we show that the negation of the desired conclusion leads to a contradiction
Answer:
True
Step-by-step explanation:
The application of an indirect proof is seen whenever we make assumptions about a given condition/statement. i.e. assuming what we are about to proof is false before proving it to be true
The indirect proof method involves some steps which are
Identify what you are trying to prove Negate the statement to be proven ( assuming the negation to be the true statement ) prove the assumption to be false then take the initial statement as a true statement.if 16^x+2=8^x-1 find x

If Elena sells 15 adult tickets, does she sell at least 100 total tickets?
Answer:
Could you post the whole question?
This sentence is not descriptive enough.
I would need how much each ticket costs, total sales, etc.
Elena is selling tickets for an amusement park.
• She sells triple the number of student tickets as adult tickets.
• She sells 8 fewer senior tickets than adult tickets.
These are just to help you all so you know how to answer it :)

Find the solution to the equation.
n + 13 = 52
Answer:
N = 39
Step-by-step explanation:
N + 13 = 52
-13. -13
N = 39
Answer:
n = 39
Step-by-step explanation:
To find what n equals, I want to get it alone on one side of the equation.
To do this, I move 13 to the right side of the equation by subtracting 13 from both sides.
13-13=0 so n is the only value on the left side
52-13=39.
You are now left with n = 39
To check that this is right, add 13 to 39. It equals 52, so you know the answer you found is correct.

If 2 = 6, what is the degree measure of 5?
A. 80
B. 220°
C. 60°
D. 120°
Answer:
60°
Step-by-step explanation:
We know that 2 and 6 = 60 degrees, so we add 60 + 60 which equals 120, now subtract 120 by 180 and you get 60 degrees.
Julie says the most amount of time spent on homework is 1/2 times the least amount of time spent of homework. Is she correct? Explain
Answer:
Step-by-step explanation:
I believe this question is coming from a statistical data, which for whatever reasons is not present here. If Julie says the most amount of time spent, it meant that the time most time people spent on the homework. And if she says the least amount of time. This means that the least number of time people spent on the homework.
Then again, she says it is half times, this means that if 5 people spent the most amount of time in doing something, then 10 people must have spent the least amount of time doing the same exact thing.
I hope you understand
What is the slope of the line that passes through M(-6, 1) and N(2, 5)?
Answer:
m = 1/2
Step-by-step explanation:
As we move from M to N, the x-coordinate increases from -6 to 2, a jump ('run') of 8 units. Likewise, the y-coordinate increases from 1 to 5, a jump of 4 units. The slope of the line passing through these two points is thus
m = rise / run = 4/8 = 1/2

Step-by-step explanation:
Use the Rational Zero Theorem to list all possible rational zeros for the given function. f(x) = 10x^5 + 8x^4 - 15x^3 +2x^2 - 2
Given:
The function is:
[tex]f(x)=10x^5+8x^4-15x^3+2x^2-2[/tex]
To find:
All the possible rational zeros for the given function by using the Rational Zero Theorem.
Solution:
According to the rational root theorem, all the rational roots are of the form [tex]\dfrac{p}{q},q\neq 0[/tex], where p is a factor of constant term and q is a factor of leading coefficient.
We have,
[tex]f(x)=10x^5+8x^4-15x^3+2x^2-2[/tex]
Here,
Constant term = -2
Leading coefficient = 10
Factors of -2 are ±1, ±2.
Factors of 10 are ±1, ±2, ±5, ±10.
Using the rational root theorem, all the possible rational roots are:
[tex]x=\pm 1,\pm 2,\pm \dfrac{1}{2}, \pm \dfrac{1}{5},\pm \dfrac{2}{5},\pm \dfrac{1}{10}[/tex].
Therefore, all the possible rational roots of the given function are [tex]\pm 1,\pm 2,\pm \dfrac{1}{2}, \pm \dfrac{1}{5},\pm \dfrac{2}{5},\pm \dfrac{1}{10}[/tex].
Identify a2 in the sequence below , 12 , 7 , 2 , -3
Answer:
a₂ = 7
Step-by-step explanation:
The subscript 2 on a₂ represents the second term in the sequence.
The second term is 7 , so
a₂ = 7
The Martinez Family has driven 240 miles so far. Their total trip is 300 miles. What percentage of the trip have they already driven?
Answer:
80%
Step-by-step explanation:
Percentage of the trip covered = [tex]\frac{miles driven }{total miles}[/tex] × 100
I am multiplying by 100 because to convert to percentage, we have to multiply by 100
Miles drive = 240
Total miles = 300
[tex]\frac{240}{300}[/tex] × 100 = 80%

a rectangular canvas covers 225 square inches on a wall. If the canvas has a height of 18 inches then what is the base?
Answer:
12.5 Sq inches
Step-by-step explanation: 225 is the area and the formula for area is b*h (base times height) and from the problem, you can see that 18 inches is the height. In this case you would do 225/18 which gives you 12.5 sq inches.
