Classify each pair of lines as parallel, perpendicular, coinciding, or intersecting at a non-right angle:

Vaselesa [24]

M= y2-y1/x2-x1

Line 1: 3-(-5) / 0-4 = -2
Line 2: 5-11 / (-1)-(-4) = -2

Since the slopes are the same they are parallel

The answer is 20.5

Subtract both 7.5 and 22 from 50

50-7.5 = 42.5

42.5 - 22 = 20.5

Assume y varies directly as x. If y = 30 when x = -3, find y when x = -9.

navik [9.2K]

Answer:

y is 90

Step-by-step explanation:

The y/x is proportional per point (x,y) since this is a direct variation.

That is ,

$\frac{30}{-3}=\frac{y}{-9}$ .

Cross multiply:

$30(-9)=y(-3)$

Simplify:

$-270=-3y$

Divide both sides by -3

$\frac{-270}{-3}=y$

$90=y$

How do i complete these patterns

Ghella [55]

For a, each time it is taking away 2 places. 3,400,000, taking away 2 zeros is 34,000. Like they have in the example. So you need to take away 2 places for the first blank. For the second blank you need to move the decimal place 2 places to the left. For b, it's taking away 1 place, so do the same thing but with one place. For the first blank, add a place.
