Answer:

Answer:

n = 1

Step-by-step explanation:

This equation is just basic alegebra. First, combine like terms to get

9 - n = 8n. (Because 3 - 3 = 0, and -4n + 3n = -n.) Now the equation is much simpiler; add n to both sides to get 9 = 9n. Divide 9 by both sides to get that n = 1.

You can check your answer by plugging 1 in for n.

9 - 4(1) + 3(1) = 8(1) + 3 - 3

9 - 4 + 3 = 8 + 3 - 3

5 + 3 = 11 - 3

8 = 8

Therefore, n is proven to equal 1.

Which of the following functions is not a linear

kicyunya [14]

By looking at the degree of the polynomials, we conclude that the option that is not linear is option C.

<h3>Which of the following functions is not a linear function?</h3>

A polynomial is an expression of the form:

$p(x) = a_n*x^n + a_{n-1}*x^{n-1} + ... + a_0$

Where all the exponents are natural numbers.

We define the degree of a polynomial as the largest exponent, and we define a linear function as a polynomial of degree 1.

So a linear function is of the form:

$f(x) = a_1*x + a_0$

Now, if you look at option C, you can see that the degree of that polynomial is 2. So that is not a linear function.

Then the correct option is C.

Part of the proceeds from a garage sale was $455 worth of $5 bills and $20 bills. If there were 6 more $5 bills than 20$ bills f

Feliz [49]

Answer:

$\large \boxed{\text{17 \$20 bills and 23 \$5 bills}}$

Step-by-step explanation:

Let x = the number of $20 bills.

Then x + 6 = the number of $5 bills and

20x + 5(x + 6) = 455

$\begin{array}{rcl}20x + 5(x + 6) & = & 455\\20x + 5x + 30 & = & 455\\25x + 30 & = & 455\\25x & = & 425\\x & = &\dfrac{425}{25}\\\\x & = &\mathbf{17}\\\end{array}$
