Identify the equation of the line perpendicular to 9x - 3y = 18.

sweet [91]

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The exemplar equation has slope

9x - 3y = 18

- 3y = -9x + 18

y = 3x - 6

m = 3

so perpendicular slope will be -1/3

D has such a slope

3y = -x + 1

y = (-1/3)x + 1/3

This is my question

Talja [164]

Answer/Step-by-step explanation:

∆ABC is similar to ∆CDE. Therefore, the ratio of their corresponding sides are proportional.

This,

$\frac{DE}{AB} = \frac{DC}{AC}$

$\frac{4}{3} = \frac{x + 3}{x + 1}$

Solve for x

$4(x + 1) = 3(x + 3)$

$4x + 4 = 3x + 9$

$4x + 4 - 4 = 3x + 9 - 4$

$4x = 3x + 5$

$4x - 3x = 3x + 5 - 3x$

$x = 5$

Use the value of x to find AC and DC

$AC = x + 1 = 5 + 1 = 6$

$DC = x + 3 = 5 + 3 = 8$
