Let a and b be any two integers. Show that the following statement is false: If 3|(a+b),then 3|(a−b).Hint. To show that the stat
Phoenix [80]

Answer with Step-by-step explanation:

Let a and b are two integers.

We have to show that

if 3\a+b then 3\a-b is false.

In order to prove that given statement is false we prove this with the help of example

Suppose we have two integers a=2 and b=4

if 3\2+4

3\6=2

2-4=-2

But 3 does not divide -2.

Therefore, the given statement is false.

Hence, proved.

2. If you used the 23 cm basketball as your Moon sphere, how big
castortr0y [4]

Ok so I heard this question a few times already and couldn't remember how it went so I decided to put my brain to the test, I used my algebra to use and complete it.

If the Earth were shrunk down to the size of a basketball (radius:4.69 inches) the Moon would be a tennis ball (radius: 1.2768 inches, to be exact) 23.5 feet away.

The Sun would be a 42.6-foot sphere (source) located 1.7 miles away.

The closest star, Proxima Centauri, would still be 463,151 miles away – almost twice the distance of the actual moon."

Mr. McBride ordered 6 cheese pizzas and 7 pepperoni pizzas and paid $153.50 for his son's birthday party. He realized he was goi
Marat540 [252]

Let x = cost of one cheese pizza.

Let y = cost of one pepperoni pizza.

Set up a system of equations.

6x + 7y = 153.50

2x + 2y = 47.00.

Multiply the second equation by -3

6x + 7y = 153.50

-6x - 6y = -141.00.

Add the equations together

y = $12.00.

Plug 12 into one of our original equations.

2x + 2(12) = 47.

Simplify the left side.

2x + 24 = 47.

Subtract 24 from each side.

2x = 23.

Divide each side by 2

x = $11.50

In conclusion, one pepperoni pizza costs $12.00

Consider vectors u and v, where u = (1, -1) and v = (1, 1). What is the measure of the angle between the vectors?
7nadin3 [17]

Answer:

I believe the answer is C. 90 degrees

Step-by-step explanation:

First you find the lengths of the two vectors, which are both \sqrt{2}. Then you find the angle given the cos using:   cos(∅)=\frac{u*v}{|u|*|v|} = \frac{0}{\sqrt{2}*\sqrt{2}  } = 0. Then using ∅=acos(0)=\frac{\pi }{2} = 90°
