Answer:

The answer to your question is below

Step-by-step explanation:

a) $\frac{s^{2}- 3s - 28 }{s - 7}$

Factor the numerator is a polynomial of the form x² + bx + c

s² - 3s - 28 = (s - 7)( s + 4)

Substitute

$\frac{(s - 7)(s + 4)}{(s - 7)}$

Simplify like terms

Result s + 4

b) $\frac{c^{2} + 5c - 24}{c + 8}$

Factor the numerator is a polynomial of the form x² + bx + c

c² + 5c - 24 = (c + 8)(c - 3)

Substitute

$\frac{(c + 8)(c - 3)}{c + 8}$

Simplify like terms c - 3

Result c - 3

Find the point at which the line joining the two points (-3,-5) and (7,5) cuts they y axis

8090 [49]

Answer:

(0,-2)

Step-by-step explanation:

First we find the equation of the line passes through $(-3,-5)$ and $(7,5)$ .

The slope of the line is

$m=\frac{5-(-5)}{7-(-3)}\\=\frac{10}{10}\\=1$

So by the point slope formula the equation of the line is

$y-5=1(x-7)\\y=x-7+5\\y=x-2$

When $x=0$ we have $y=0-2=-2$ .

Therefore the line joining the two points cuts the y-axis at (0,-2).

Find the slope of the line that is parallel and perpendicular <br><br> -7x-2y=4

Rus_ich [418]

$\bf -7x-2y=4\implies -2y=7x+4\implies y=\cfrac{7x+4}{-2}\implies y=\cfrac{7x}{-2}+\cfrac{4}{-2} \\\\\\ y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{7}{2}} x-2\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill$

$\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{-\cfrac{7}{2}}\qquad \qquad \qquad \stackrel{reciprocal}{-\cfrac{2}{7}}\qquad \stackrel{negative~reciprocal}{\cfrac{2}{7}}}$

now, what's the slope of a line parallel to that one above? well, parallel lines have exactly the same slope.
