5 pts Question 17 - + - = -6/14 -7/8 6/24 09/14

Nady [450]

Answer:

-7/8

Step-by-step explanation:

$\frac{ - 3 \times 8}{6 \times 8} + \frac{ - 3 \times 6}{8 \times 6} = \frac{ - 24 - 18}{48} = \frac{ - 42}{48}$

$= \frac{ - 7}{8}$

How to solve this question

yarga [219]

Answer:

BC = 3.6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{BC}{DE}$ = $\frac{AC}{AE}$ , substitute values

$\frac{BC}{1.2}$ = $\frac{4.5}{1.5}$ ( cross- multiply )

1.5 BC = 5.4 ( divide both sides by 1.5 )

BC = 3.6

Describe and correct the error in writing an equation of the line shown

Rudiy27

Answer:

$y = -\frac{3}{5}x+4$

Step-by-step explanation:

Given:

$(x_1,y_1) = (0,4)$

$(x_2,y_2) = (5,1)$

The attachment completes the question

From the attachment, the slope of the line was calculated as:

$m = \frac{1-4}{0-5}$

This step is inaccurate because the slope of a line is calculated using

$m = \frac{y_2-y_1}{x_2-x_1}$

Which gives

$m = \frac{1-4}{5-0}$

$m = \frac{-3}{5}$

$m = -\frac{3}{5}$

The line equation is then calculated using:

$y -y_1 = m(x - x_1)$

Substitute values for m, x1 and y1

$y - 4 = -\frac{3}{5}(x - 0)$

$y - 4 = -\frac{3}{5}(x)$

Open bracket

$y - 4 = -\frac{3}{5}x$

Make y the subject

$y = -\frac{3}{5}x+4$

How do I solve this??

WITCHER [35]

v + 9 / 3 = 8

v + 9 = 24

v = 24 - 9

v = 15

If you have any questions on how I got to this solution, please ask. :)
