Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −3x+5y=−15? Drag and drop each choice in

nexus9112 [7]

The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.

<h3>How can the slope of the line be calculate?</h3>

The slope of the line is been given as −3x+5y=−15

Then $y= \frac{3}{5x} -3$ , hence the slope is $\frac{3}{5}$

Slope of the first line 5x + 3y = 15 after calculation is

the slope is $y= \frac{5}{-3x} +5\\\\\frac{5}{-3}$

this means that the line is perpendicular to the given line

Slope of the second line 3x + 5y = 15 after calculation is

$y= \frac{3}{-5x} +15\\\\\frac{3}{-5}$

This means that the line is not perpendicular and not parallel

Slope of the Third line -3x + 5y = 15 can be calculated as

$y= \frac{3}{5x} +15\\\\\frac{3}{5}$

This means that the line is parallel to the above line.

Slope of the first line 3x + 5y = 15 after calculation is

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

This means that the line is not parallel or perpendicular to the line

Trinh is serving 112 people cake , 5/8ths are getting chocolate how many people will get carrot ?

Novay_Z [31]

Hey!

If 112 people are getting cake and 5/8 are getting chocolate, that means the remaining will get chocolate.

8/8 - 5/8 = 3/8

3/8 are getting chocolate. You have to find 3/8 of 112.

3/8 × 112 = 336/8 = 42

42 people are getting carrot cake

The length of a rectangle is 4 less than twice the width. The area of the

Zolol [24]

Answer:

Width: 7 Length: 10

Step-by-step explanation:

Width: x

length: 2x-4

Area: 70 meters squared

(2x-4)x=70

2x^2-4x=70

2x^2-4x-70=0

2(x^2-2x-35)=0

(x-7)(x+5)=0

x cannot be negative so x=7
