Answer:

Step-by-step explanation:

Basically when the equation is adding you subtract from each side of the equation....

So:

x + 40 = 75

-40 = -40

75 - 40 = 26

x = 26

X equals 26 because I subtracted 49 from 75

15% = 0.15

15.50 * 0.15 = 2.325
15.50 + 2.325 = 17.825
17.825 rounded to $17.83

Find the equation of a line that is parallel to line g that contains (P, Q).

Fofino [41]

Correct option:

$\boxed{x-y=P-Q}$

<h2>Explanation:</h2>

Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ (x_{1},y_{1})=(-3,2) \\ \\ (x_{2},y_{2})=(0,5) \\ \\ \\ m=\frac{5-2}{0-(-3)}=1$

So we can write the point-slope form of the equation of the line as follows:

$y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}$

Divide (x^3-20x+16)/(x-4)

Lorico [155]

$\frac{( x^{3}-20x+16) }{(x-4)}$

Use the rational root theorem:
$a_{o}$ =16, $a_{n}$ =1

The dividers of $a_{o}$ : 1,2,4,8,16
The dividers of $a_{n}$ : 1

Therefore, check the following rational numbers: +- $\frac{1,2,4,8,16}{1}$

$\frac{4}{1}$ is a root of the expression, so factor out x-4

Compute $\frac{ x^{3}-20x+16 }{x-4}$ to get the rest of the equation.

$\frac{(x-4)( x^{2} +4x-4)}{x-4}$

Cancel the common factor:
$x^{2}+4x-4$ is the final answer
