Answer: Hello there!

we know that y is a positive integer, and we have the equation:

x - (-y) = z

we want to know if z > x

where we suppose that x and z are real numbers.

Now, the sign rule is the following:

(+)(+) = +

(-)(+) = -

(+)(-) = -

(-)(-) = +

Then the equation x - (-y) = z can be rewritten as:

x - (-y) = x + y = z

now let's isolate x

x = z - y

this means that the number x is equal to the number z decreased by the number y.

then the number z is bigger than the number x.

Answer:

Yes, <em>z</em> will be greater than <em>x.</em>

Step-by-step explanation:

Given expression is x- (-y)=z \ for \ y \ is \ a \ positive \ integer.

now let <em>y = 2 </em>and <em>x = 1</em>

Then, x- (-y)=z \\1+2 = 3 \\\\

where z> x i.e. <em>3 > 1</em>

on simplifying the given  expression in terms of y

y=z-x

now suppose if <em>x = 7 and z=3 </em>then,

y = (z-x) = (3-7) = (-4)

which gives value of y in terms of negative integer which is not possible according to the given statement since y is a positive integer. Therefore, if y is a positive integer then  z will be greater than x.

Answer:

X = 4

Step-by-step explanation:

In the equation add 3 to both sides of the equation

1/2x-3+3=2-3/4x+3

Simplify

1/2x = -3/4x + 5

Add 3/4x to both sides

1/2x + 3/4x = -3/4x + 5 + 3/4x

Simplify

5/4x=5 Multiply both sides by 5

5x=20 divide both sides by 5

5x divided by 5 and 20 divided by 5

Which of the following indicates that the roots of a quadratic are irrational
yan [13]
Answer would be D  You can have a rational discriminant for an irrational root, but you can also have rational discriminant for a rational root. So C is partially correct. 

<span>All prime discriminants will result in an irrational root, but not all irrational roots have prime discriminants </span>
