Which line is parallel to the line 8x + 2y = 12?

velikii [3]

Answer:

Step-by-step explanation:

Our line's equation is;

2y = -8x + 12

Dividing throughout by 2 we get;

y = -4x + 6

The slope of our line = -4

We are to choose a line whose slope is -4 (from those four options)

A slope of -4 means that for every positive 1 move along the x-axis, there is a negative 4 move along the y-axis.

The line that satisfies this condition is the third line.

Do the ratios 10/8 and 16/20 form a proportion<br><br> Yes or no?

ziro4ka [17]

Answer:

No. Reduce 10/8 by dividing by 2. 10/8= 5, 8/2= 4. 10/8= 5/4. Reduce 16/20 by dividing by 4. 16/4= 4 , 20/4= 5. 16/20= 4/5.

Find the missing segment in the attached image

xz_007 [3.2K]

Answer:

The length of the missing segment is 24

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

$\frac{15}{x} = \frac{15+5}{8+x}$

$\frac{15}{x} = \frac{20}{8+x}$

Cross Multiply

$15 * (8 + x) = 20 * x$

Open bracket

$15*8 + 15 * x = 20 * x$

$120 + 15x = 20x$

Subtract 15x from both sides

$120 + 15x -15x= 20x-15x$

$120 = 20x-15x$

$120 = 5x$

Divide both sides by 5

$\frac{120}{5} = \frac{5x}{5}$

$\frac{120}{5} = x$

$24 = x$

$x = 24$

Hence, the length of the missing segment is 24
