If x / y is an integer, which of the following statements must be true?A. both x and y are integers
B. x is an integer
C. either x or y is negative
D. y / x is an integer
E. x = ny where n is an integer

Answers

Answer 1
Answer: Only E) is true. If I were to arbitrarily pick x = 2.2 and y =1.1, then I could show that A), B), C), and D) to be false, given x/y = 2.2/1.1 = 2 (which is an integer). However for E), if we define x/y = n where n is an integer, then by rearranging terms, we can show x = n*y where n still equals an integer and our original equation is still valid.

A 50 METER PATH SURROUNDS A RECTANGULAR GARDEN. THE WIDTH OF THE GARDEN IS TWO-THIRDS ITS LENGTH. FIND ITS AREA.

Answers

 X is the length, so the width is 2/3×

Then 5/3× = 50 and x = 50.3/5 = 30 the width = 30.2/3 = 20
The area = 20.30 = 600 m^2

As a member of a music club, you can order CDs for $14.99 each. The music club also charges $4.99 for each shipment. The expression 14.99n + 4.99 represents the cost of n CDs. Find the total cost for ordering 3 CDs.

Answers

howdy!

using the expression 14.99(n) + 4.99, the total of 3 CDs would cost $49.96.
in the expression 14.99n +499... replace the N with 3... 14.99(3)+ 4.99= 49.96

Find 11/12+(-7/12). Write your answer as a fraction in simplest form

Answers

Answer: 1/3

Step-by-step explanation:

To add fractions with different denominators, we first need to find a common denominator. In this case, the common denominator is 12.

11/12 + (-7/12) = (11 - 7) / 12

Simplifying the numerator gives us:

4/12

We can further simplify by dividing both the numerator and denominator by their greatest common factor, which is 4.

4/12 = 1/3

Therefore, 11/12 + (-7/12) = 1/3.

What is the slope of a line perpendicular to the line whose equation is 2y=-6x+8 1)-3
2)1/3
3)1/6
4)-6

Answers

2y=-6x+8

First, the slope of any equation, is always the coefficient with the variable "x".

So, the slope for this line, is -6x.

To get rid of the coefficient with y, we need to divide 2, from both sides of the equal sign.

2y=-6x+8

      2

y=-3+4

Now that we have our new equation, we can see that the slope of our line has also changed, from -6x to-3x. Because -6÷2=-3.

And to find the perpendicular slope, you change the reciprocal of the slope so from -3 to  1/-3 and then you change the sign of the slope so from 1/-3 to 1/3. That is your final answer.

The answer is 2) 1/3.


Your supposed to get Y by its self. So do this- (-6x+8)/2You should get y=-3x+4So the slope would be -3 of the original line.The perpendicular slope would be the reciprical and opposite sign of it, so it should be 1/3. hope this helps
