Which polynomial identity will prove that 16 = 25 − 9?

Greeley [361]

Should be a) difference of squares since 25 and 9 are both perfect squares. A radical will simply that into (5-3) squared, which equals 16.

What is the solution to the system of equations below? y = one-half x minus 4 and y = negative 2 x minus 9 (–2, –5) (–2, –3) (2,

Maurinko [17]

We have been given a system of equations $y=\frac{1}{2}x-4$ and $y=-2x-9$ . We are asked to find the solution of our given system of equations.

To solve our system of equations, we will equate both equations as:

$\frac{1}{2}x-4=-2x-9$

$\frac{1}{2}x-4+4=-2x-9+4$

$\frac{1}{2}x=-2x-5$

$\frac{1}{2}x+2x=-2x+2x-5$

$\frac{1}{2}x+\frac{4}{2}x=-5$

$\frac{1+4}{2}x=-5$

$\frac{5}{2}x=-5$

$\frac{2}{5}\cdot \frac{5}{2}x=-5\cdot \frac{2}{5}$

$x=-2$

Upon substituting $x=-2$ in equation $y=-2x-9$ , we will get:

$y=-2(-2)-9$

$y=4-9$

$y=-5$

Therefore, the solution of our given system of equations would be $(-2,-5)$ and option A is the correct choice.

scoray [572]

Answer:

The price of collection of novels before taxes was <u>$409.10</u>.

Step-by-step explanation:

Given:

Ava bought a collection of hardcover novels and paid $450 including sales tax.

The sales tax is 10%.

Now, to find the price of collection of novels before taxes.

Let the price of collection of novels before sales tax be $x$ .

The price of collection of novels including sales tax = $450.

Rate of sales tax = 10%.

Now, to get the price before sales tax by putting an equation:

$x=450-10\%\ of\ x$

$x=450-\frac{10}{100} \times x$

$x=450-0.10\times x$

$x=450-0.10x$

<em>Adding both sides by 0.10</em> $x$ <em> we get:</em>

<em /> $1.10x=450$ <em />

<em>Dividing both sides by 1.10 we get:</em>

$x=\$409.10.$

Therefore, the price of collection of novels before taxes was $409.10.
