Answer:

56

Step-by-step explanation:

Given expression:

          x - f(x) = -7

            f(x) = 63

Unknown:

The value of x  = ?

Solution:

We can easily solve this problem by simple substitution:

         Since;

             x - f(x) = -7

  and f(x) = 63;

           x - 63  = -7

            x  = -7 + 63

             x  = 56

Olegator [25]

Answer:

Okay, so we know a number of students and the amount of girls as a bracket. So what we have to do now is multiply them with each other.

28 *4/7 = 16

So there are 16 girls in Mr. Chang´s class.

Which of the following is a polynomial?
Makovka662 [10]

Answer:

D

Step-by-step explanation:

Terms are separated by addition and subtraction symbols.

Polynomials consist of terms that are constant and/or variable. The variable terms must have 0 or positive exponents. Polynomials will not consist of division of variable expressions.

Examples of polynomials:

5

5x

6-x

24x^9-x

Examples of non-polynomials:

\sqrt{x}

\frac{x+2}{x-4}

In general a polynomial when written in standard form should be comparable to:

a_nx^n+a_{n-1}x^{n-1}+\cdots a_3x^3+a_2x^2+a_1x+a_0

where the a's could be zero and all the exponents,n, are positive or 0.

D is comparable since all of these are 0 except x_4 which is 1 and x_0 which is -2.

Also the other choices have either division by variable expressions and/or negative exponents on variables.
