Find an ordered pair (x, y) that is a solution to the equation
2x-y=4
answer:
ordered pair is (2,-4)
Show that if x, y, z are integers such that x^3+5y^3 = 25z^3, then x = y = 0.
Answer:
3125*k^9 + y^3 is an integer my closure property.
but 5^(1/3) is not an integer, which forces z to be irrational.
Note that there is no way an integer value can rationalize 5^(1/3)
Step-by-step explanation:
x^3 = 25z^3 - 5y^3
x^3 = 5 ( 5z^3 - y^3)
x = (5 ( 5z^3 - y^3) )^(1/3) must be an integer
= 5^(1/3) * (5z^3 - y^3)^(1/3)
Then (5z^3 - y^3)^(1/3) = 25*k^3 for some integer k
5z^3 - y^3 = 15625*k^9
5z^3 = 15625*k^9 + y^3
z^3 = 3125*k^9 + (1/5)*y^3
z = ( 3125*k^9 + (1/5)*y^3 )^ ( 1/3)

Answer:
c. 2+4(n-1)
b. 4+3(n-1)
Step-by-step explanation:
Look at the pattern: it starts at 2, and each term afterwards goes up by 4 each time. 2+4 = 6+4 = 10... et cetera.
2+4(n-1) is the equation.
Test this out with the fifth term.
t₅ = 2 + 4(n-1) = 2 + 4*4 = 2+16 = 18
Test it out with the first term, too.
t₁ = 2 + 4(n-1) = 2 + 4(0) = 2
If you follow the same pattern with part b, you find that the equation is
4+3(n-1)
Test it in the same manner.

(5.67x - 8.16)+(3.6x + 9.2)
you dont have to find x you only have to simplify it
Answer:
Step-by-step explanation:
5.67x - 8.16 + 3.6x + 9.2
Write the like terms together
= 5.67x + 3.6x - 8.16 + 9.2
{8.16 & 9.2 have different sign, so subtract and the result will have the bigger numbers sign}
= 9.27x + 1.04

If a = 10 and b =
-4, explain how to find the number of solutions to the equation.
Answer:
No solution
Step-by-step explanation:
4+ 2(5x-8)=ax+b
1. Plug in values: 4 + 2(5x-8) = (10)x + (-4)
2. Combine Like Terms: 4 + 10x -16 = 10x -4
3. Add 10x to both sides: 4 -16 = -4
4. Combine Like Terms: -12 = -4
-12 does not equal -4, so there is No solution

What is the slope of y = 6x+2
Stuck? Watch a video or use a hint.
Answer:
slope = 6
Step-by-step explanation:
The equation of a line in slope- intercep form is
y = mx + c ( m is the slope and c the y- intercept )
y = 6x + 2 ← is in slope- intercept form
with slope m = 6

The number in the chart are the math test scores of 10 seventh hrade students.
Which of the following is most affected by the lower score?
A.) the mean and median
B.) the median
C.) the mean
D.) the mode
Answer:
C
Step-by-step explanation:
The mean of a set of values is the average of all of them. The median is just the center most value when you arrange the values in order from least to greatest, or the average of the most central two if there is an even number of values. The mode is simply the value that shows up the most. The single, low outlier does not affect the median and mode almost at all, and only has a large influence on the mean, since it brings down the average. Therefore, the correct answer is choice C. Hope this helps!
Answer:
The mean... the median is in the middle, it won't change, the mode is the most repetitive number and it won't change neither... so the mean will be the most affected.

Answer:
x=4
Step-by-step explanation:
y = 2x - 8
Let y =0
0 = 2x-8
Add 8 to each side
8 = 2x-8+8
8 = 2x
Divide each side by 2

Prove that for any natural n the number 3^(n+4)−3^n is divisible by 16.
Answer:
Proved (See Explanation)
Step-by-step explanation:
Show that 3ⁿ⁺⁴ - 3ⁿ is divisible by 16.
This is done as follows
[tex]\frac{3^{n+4} - 3^n}{16}[/tex]
From laws of indices;
aᵐ⁺ⁿ = aᵐ * aⁿ.
So, 3ⁿ⁺⁴ can be written as 3ⁿ * 3⁴.
[tex]\frac{3^{n+4} - 3^n}{16}[/tex] becomes
[tex]\frac{3^n * 3^4 - 3^n}{16}[/tex]
Factorize
[tex]\frac{3^n(3^4 - 1)}{16}[/tex]
[tex]\frac{3^n(81 - 1)}{16}[/tex]
[tex]\frac{3^n(80)}{16}[/tex]
3ⁿ * 5
5(3ⁿ)
The expression can not be further simplified.
However, we can conclude that when 3ⁿ⁺⁴ - 3ⁿ is divisible by 16, because 5(3ⁿ) is a natural whole number as long as n is a natural whole number.

Ariana buys an ant farm from a store near her home. The ant farm's price is $12 and the sales tax is 7%. What is the total price of the ant farm? 100 points
Answer: The total price for ant farm is $12.84
Step-by-step explanation:
The price of ant farm = $ 12
The sales tax on the price = 7%
Noe, 7% of $12 =
⇒The tax amount on the price = $0.84
So, the Taxed amount = The original price + Tax
$ 12 + $0.84 = $12.84
