Remember that straight lines are 180°. For #1 angle 1 would be 40°, since 140°+40°=180°

Write the point-slope form with two points ..of the given line that passes through the points (0, -3) and (4, 1). Identify (x1,

frez [133]

You need to find the slope too.
$m = \frac{y2 - y1}{x2 - x1} = \frac{ - 3 - 1}{0 - 4} = \frac{ - 4}{ - 4} = \frac{1}{1}$
point slope formula y - y1 = m(x - x1)
use (0, -3)
y - (-3) = 1 (x -0)
y + 3 = 1x

Answer:

see explanation

Step-by-step explanation:

Given

$\frac{9}{a^2+9a+20}$ , $\frac{7a}{a^2+11a+28}$

Factor the denominators of both fractions

$\frac{9}{(a+4)(a+5)}$ , $\frac{7a}{(a+4)(a+7)}$

The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)

Multiply numerator/denominator of first fraction by (a + 7)

Multiply numerator/denominator of second fraction by (a + 5 )

$\frac{9(a+7)}{(a+4)(a+5)(a+7)}$ , $\frac{7a(a+5)}{(a+4)(a+5)(a+7)}$ , then

$\frac{9a+63}{(a+4)(a+5)(a+7)}$ , $\frac{7a^2+35a}{(a+4)(a+5)(a+7)}$
