Perpendicular line has slope that multiplies to -1
paralel line has same slope

y=mx+b
slope=-7/4
perpendicular
4/7
(-7,-2)
-2=4/7(-7)+b
-2=-4+b
add 4 both sides
2=b
y=4/7x+2


paralel
y=-7/4x+b
-2=-7/4(-7)+b
-2=49/4+b
minus 49/4 from both sides (-2=-8/4)
-57/4=b
y=-7/4x-14.25


perpendicular
y=4/7x+2
paralel
y=-7/4x-14.25

Rose has a playlist with 40 rock songs and 28 country songs. What is the ratio of country songs to rock songs on the playlist?
cupoosta [38]
<em>The answer is 10:7, 10/7, 10 to 7. Whichever it's asking for. As long as you know the ratio is 10 rock songs to 7 country songs.
</em>
<em /><u>
</u><em />This problem can be a simple fraction simplification problem. Here's what I mean:
<em>
</em>
<em />So, we have 40 rock songs and 28 country songs. Let's put that into a fraction:
<em>
</em>
\frac{40}{28}
<em>
</em>To simplify this as much as possible, all we have to do is find the greatest common multiple and divide it by both numbers. the GCF is 4, so all you have to do is divide 40 by 4 and 28 by 4 to get your ratios.

I hope this helped!!

O (1.4)<br> O (0.6)<br> O (2, 3)<br> O (5,0)
Illusion [34]

Answer:

(0.6)

Step-by-step explanation:

the y intercept is determined by wherever x = 0

the ordered pair (0,6) has the x value equaling 0

therefore (0,6) represents the y-intercept

CAN SOME ONE HELP ME ITS URGENT
aniked [119]

As we can observe from given information,

  • UT = ST

  • 2x + 5 = x + 12

  • 2x - x = 12 - 5

  • x = 7

now, let's solve for y

  • RU = RS

  • y - 4 = x + 5

  • y - 4 = 7 + 5

  • y = 12 + 4

  • y = 16

hope it helped...

Find the quotient of `(2i(4+5i)(4-5i))/(4+i)`, and express it in the simplest form.
DIA [1.3K]

Answer:

(328i + 82)  /  17

Step-by-step explanation:

`(2i(4+5i)(4-5i))/(4+i)

= (2i(16 - 25i^2)) / (4 + i)

= (2i( 16 + 25) )) / (4 + 1)        [Note:- i^2 = -1]

=  82i / (4 + i)

= 82i(4 - i) / (4 + i)(4 - 1)

= 328i  + 82 /   (16 - i^2)

= (328i + 82)  /  17
