Problem 5
A counterexample could be a number like 6. Divide it over 2 and we get 6/2 = 3, which is a whole number. This shows 6 is a multiple of 2. However, 6/4 = 1.5 is not a whole number, so 6 is not divisible by 4. The overall claim is false.
======================================================
Problem 6
Let's say we are subtracting a positive number and a negative number. For instance, let's say we're subtracting 10 and -7
So,
10 minus -7 = 10 - (-7) = 10+7 = 17
When subtracting a negative, the two minus signs cancel to form a plus sign. The result we get is 17, which is larger than the greater number 10. So this is one counterexample that proves the claim to be false.
======================================================
Problem 7
Start with a circle. The circle can be any size. Plot four random points on the circle. The points can be anywhere you want. Let's label those points A,B,C,D. Form quadrilateral ABCD.
Now let's say we pick point A and pull it off the circle and pull it outside the circle. Points B,C and D remain on the circle. This is one example where we cannot draw a circle through this new arrangement of points. The circle goes through B,C, and D just fine; however, it doesn't go through point A. If you try to attempt to get the circle to go through A, then you'll have to pick B,C or D to ignore. In other words, you'll only be able to pick three points that the circle can go through. Therefore, a circle cannot be drawn as described for every quadrilateral.
Note: Any quadrilateral that has all four points on the same circle is known as a cyclic quadrilateral.

Find the number of outcomes in the complement of the given event. Out of 246 shoes in a department store, 198 are women's shoes.
Answers
Answer:
I suppose that the event here is selecting randomly a shoe.
We know that there are 246 shoes in the store, and 198 of them are women's shoes.
Then there are 246 - 198 = 48 shoes that are not women's shoes.
This means that if the event is something like "finding randomly a women's shoe"
The complement would be "selecting randomly a shoe which is not a women's shoe"
And there will be 48 outcomes that meet this condition.

Find the slope intercept equation of the line
Answers
Answer:
Step-by-step explanation:
slope-intercept formula looks like [y=mx + b]
use two points to find the slope.. or look at the graph carefully to see it there are easy points to count from.... hmmm
yes.. this is very easy to just count.. no math needed :P
the slope is posive. b/c the graph looks like you are walking up hill.. and it's rise over run is 2/1 .. so the slope is 2
then by looking at the graph I can also see that when x = 0 the line pass exactly thur +1.. sooo that tells me all I need to know for the sloop-intercept formula

Answer:
8 hours and 54 minuter
Step-by-step explanation:
1 hour is equal to 60 minutes
we have 8 hours and 0.9 hours
0.9*60=54 minutes
we have 8 hours and 54 minuter
Answer:
The last one
Step-by-step explanation:
First you need to figure out how many minutes are in 0.1 hours
you can do this by dividing 60 minutes by 10
you get 6
multiply 6 and 9 so that you can find out how many minutes 0.9 hours are
this leaves you with 54 minutes
so your answer is 8 hours and 54 minutes
f(x)=6x+4. Find the inverse of f(x).
Answers
Answer:
c
Step-by-step explanation:
f(x)=6x+4
y=6x+4
x=6y+4
6y=x-4
y=(x-4)/6
f^-1(x)=(x-4)/6
Answer is Option-C
How to find Inverse Function:
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y.
(Here), Given
f(x) = 6x + 4
Let's inverse function be y.
y = 6x + 4
First step is to switch the positions of x and y.
Inverse: x = 6y + 4
x - 4 = 6y
=> y = (1/6) * (x - 4)

Equilateral triangles are

acute triangles. Yes, because acute is always 60 degrees, and equilateral is basically your average triangle, so its corners have 60 degrees.
Scalene triangles are
sometimes
acute triangles. Scalene triangles always dont have that sharp corner..they sometimes do, the sharp turn which is 60 degrees, ACUTE IS ALWAYS 60 DEGREES.
Right triangles are

acute triangles. A right angle cant be a acute, not 60 degrees..

12x - 4 = 4(2x + 1)
Answers
Answer:
X = 2
Step-by-step explanation:
12x - 4 = 4(2x + 1) (multiple 2x and 1 by 4)
=> 12x - 4 = 8x + 4
=> 12x - 8x = 4+4 (and the alike terms together)
=> 4x = 8
=> x = 8/4 ( divide 8 and 4 by 4)
=> x = 2/1
=> x = 2
