Answer:
Hypothesis
a. If two integers are even
Conclusion
b. then their sum is even
Step-by-step explanation:
We divide the statement into two parts . The first part is true only when the second is also true. The only way we can reject the hypothesis is that the conclusion is false.
In the statement "If two integers are even, then their sum is even" the part "If two integers are even" would be considered true or false on the basis of "then their sum is even" validity. So if the "then their sum is even" (conclusion ) Part is proved then the "If two integers are even" ( hypothesis) is also true.
Hence the hypothesis is
a. If two integers are even
and
Conclusion is
b. then their sum is even

The formula B = 100 + 75m gives the balance (B) of a bank account after (m) months of saving. Solve for m and then use your solution to find the number of months you would need to save to have a balance of $700.
Answer:
8 Months
Step-by-step explanation:
The formula in the problem (B = 100 + 75m) can be written as this:
(B-100)/75 = M
The problem gives us the balance (B=700), which we can plug into our new formula to find the number of months (m).
(700-100)/75 = M
M = 8

Write the recurrence relation for the nth term which is defined by multiplying the prior term by 3 and subtracting 12.
Answer: Aₙ = 3*Aₙ₋₁ - 12
Step-by-step explanation:
Here our terms will be denoted as:
Aₙ
Where this is the n-th term of the sequence.
Now we have that the recurrence relation is defined by:
"by multiplying the prior term by 3 and subtracting 12."
Then we will have that:
Aₙ = 3*Aₙ₋₁ - 12
That is the equation to find all the terms in our sequence (remember that we need to know the initial term, A₀ in order to find all the other ones)

Solve for the function X(s) in the Laplace domain by taking the Laplace transform of the following differential equations with given initial conditions. dx +9x = 161, where x(0) = 0 and (0) = 5
Answer:
X(s) = 2/[s³(s + 9)]
Step-by-step explanation:
Here is the complete question
Solve for the function X(s) in the Laplace domain by taking the Laplace transform of the following differential equations with given initial conditions.
dx/dt + 9x = 16t² x(0) = 0 and dx(0)/dt = 5
Solution
dx/dt + 9x = 16t²
Taking the Laplace transform of the differential equation, we have
L{dx/dt + 9x} = L{16t²}
L{dx/dt} + L{9x} = L{16t²}
L{dx/dt} + 9L{x} = 16L{t²}
sL{x} - x(0) + 9L{x} = 16L{t²}
L{x} = X(s)
L{t²} = 2!/s³
Substituting X(s) and L{t²} into the equation above, we have
sX(s) - x(0) + 9X(s) = 2!/s³
Substituting x(0) = 0 into the equation above, we have
sX(s) - x(0) + 9X(s) = 2!/s³
sX(s) - 0 + 9X(s) = 2!/s³
sX(s) + 9X(s) = 2!/s³
Factorizing X(s), we have
(s + 9)X(s) = 2!/s³
X(s) = 2/[s³(s + 9)]
So X(s) in the Laplace domain is
X(s) = 2/[s³(s + 9)]

So this is conversation rates. So how I like to remember conversion rates in the metric system is King Henry Doesn't Usually Drink Chocolate Milk.
K=Kilo, H=Hecto, D=Deca, U=Unit (meters, liter, grams), D=Deci, C=Centi, M=Milli.
SO between meters (which is the U) and kilometers (which is the K), there's 3 letters so kilometers is 1000 times greater than meters. SO 3.5*1000=3500.

Find all x-intercepts and y-intercepts of the graph of the function . f(x) = - x ^ 3 + x ^ 2 + 12x If there is more than one answer, separate them with commas. Click on "None" if applicable.
Answer:
The y-intercept is (0,0)
The x-intercepts are (-3,0), (0,0), and (4,0)
Step-by-step explanation:
So we have the function:
[tex]f(x)=-x^3+x^2+12x[/tex]
And we want to solve for the x- and y-intercepts.
Y)
To solve for the y-intercept, recall that the y-intercept is when the graph touches the y-axis. At that point, the x values is 0. Thus, to find the x-intercept, substitute 0 for x:
[tex]f(x)=-(0)^3+(0)^2+12(0)[/tex]
Simplify:
[tex]f(x)=0[/tex]
So, the y-intercept is (0,0)
X)
To solve for the x-intercept(s), set the function equal to 0 and solve for x:
[tex]0=-x^3+x^2+12x[/tex]
First, factor out a negative x:
[tex]0=-x(x^2-x-12)[/tex]
Factor within the parentheses:
[tex]0=-x(x-4)(x+3)[/tex]
Zero Product Property:
[tex]-x=0\text{ or } x-4=0\text{ or } x+3=0[/tex]
Divide by -1 on the first one. Add 4 on the second one. And subtract 3 on the right:
[tex]x=0\text{ or } x=4\text{ or } x=-3[/tex]
So, our x-intercepts are:
[tex](-3,0), (0,0), (4,0)[/tex]
And we're done :)

How are integers and rational numbers the same ?
Answer:
Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

Jonas is planning out his route for an upcoming race. He uses negative numbers to represent points before the finish line and positive numbers to represent points after the finish line.
On Jonas's map, there is a bridge at -91 3/4 meters, and his wife is watching him at 14 1/2 meters.
What do 0 meters represent?
Answer:
The finish line
Step-by-step explanation:
This is because, since negative numbers are used to represent points before the finish line, and positive numbers are used to represent points after the finish line, the finish line can only be represented by the number zero. Since on Jonas' map, there is a bridge at -91 3/4 metres, therefore, the bridge is 91 3/4 metres before the finish line. And, since his wife is watching at 14 1/2 metres, since this number is positive, she is 14 1/2 metres after the finish line. So, the finish line itself, will be represented by 0 metres since this is indicated a change from negative to positive.
A point on a pre-image is G(5, -2). If its image has coordinates G'(2, 1), what was the translation? (x - 3, y - 3) (x + 3, y - 3) (x - 3, y + 3) (x + 3, y + 3)
Answer:
(x - 3, y + 3 )
Step-by-step explanation:
Note G(5, - 2 ) → G'(2, 1 )
Requires 3 to be subtracted from 5 to obtain 2 and 3 to be added to - 2 to obtain 1, thus
(x, y ) → (x - 3, y + 3 ) is the translation rule
Answer:
the answer is (x - 3, y + 3 )

Joseph stated that 5/4 is a whole number because it does not repeat as a decimal. Is he correct? Why or Why Not?
Answer:
It is not a whole number.
Step-by-step explanation:
5/4 is equals to 1.25
Therefore it is still a decimal and a fraction, NOT a whole number
A pillow that usually costs $18 is marked down 25%. Use the table to find the pillow’s new price.
It would be 13.50 because 50% off of 18$ is 9$ but it’s not 50% off itS 25% off so If you take the 50% Off price of 9$ and add 4.50 (One more 1/4th) you get $13.50
