6,2,8,4,and 0 are the only possible value of the ones digit, because
6*1=6, last digit is 6
6*2=12, last digit is 2
6*3=18, last digit is 8
6*4=24, last digit is 4
6*5=30, last digit is 0
6*6=36, last digit is 6
and the whole cycle goes over again.
The next step of your proof is to subtract (a/b) from both sides.
Then you get, x = (m/n) - (a/b)
Since rationals are closed over addition, (m/n) + (-a/b) is a rational number.
Therefore, x (an irrational number) = a rational number <em>This is a false statement which is a contradiction. So, the assumption was incorrect.</em>
Thus, the sum of a rational and irrational number is an irrational number. QED
Answer:
f(x)=x^3+7
y=x^3+7
x=y^3+7
y^3=x-7
y=cube root (x-7)
f(x) inverse=cube root of x-7

Answer:
$51.30
Step-by-step explanation:
First, we find 25% of the original price, then we deduct that from the original price. Then, we find 10% of the price and deduct that also.
The original price is $76.
25% of $76 is:
= $19
We deduct $19 from $76:
76 - 19 = $57
We find 10% of $57:
= $5.7
Deducting this:
57 - 5.7 = $51.30
She will pay $51.30 for the jacket.
To answer this question, we must find the slope of line b.
We have then:
b = (3 - (- 2)) / (2 - (- 3))
b = 5/5
b = 1
Since the lines b and c are parallel, it follows that their slopes are equal.
Then
mc = b = 1
Answer:
The slope of line c is:
mc = 1
