Answer:

z=\frac{14}{8} = 1.75

Step-by-step explanation:

I will assume you are solving for <em>z</em>. To solve for a variable, we are looking to get it alone on one side of the equals side, and everything else on the other side.

Here's the given equation:

2z+\frac{3}{8}=\frac{31}{8}

Note, I turned the mixed fraction into an improper fraction. This will make it much easier to work with.

There are two terms on the left side: 2z and \frac{3}{8}. Only one of them has a Z in it, so lets move it to the right side of the equals sign. We can do this by subtracting each side by \frac{3}{8}.

2z+\frac{3}{8} -\frac{3}{8} = \frac{31}{8} -\frac{3}{8}

We can then combine like terms:

2z= \frac{28}{8}

Then, we can divide each side by 2 to turn 2z into z:

z=\frac{14}{8}

Therefore, z=\frac{14}{8} = 1.75

Suppose that the functions r and s are defined for all real numbers x as follows. =rx−x5 =sx+2x3 write the expressions for ·rsx
PolarNik [594]

Although the question's print is not clear, to the best of my knowledge, as I can see, We are given that:

r(x)=-x^5 and s(x)=2x^3

No, we know that, by definition:

(r.s)(x)=r(x)\times s(x)

\therefore (r.s)(x)=-x^5\times 2x^3=-2x^8

Thus, for the functions r and s which are defined for all real numbers x, the answer to the question asked is:

(r.s)(x)=-2x^8

What is an integer? ​
BartSMP [9]

Answer:

A integer is any number that is not either a decimal or a fraction (however, both 2.000 and 2/2 are integers because they can be simplified into non-decimal and non-fractional numbers), this includes negative numbers. A whole number is any positive number(0 through infinity) (including non-integers)

Step-by-step explanation:

it's basically a just any number but can't be a decimal or fraction
