Answer:

First find the gradient (m).

Pick any two points on x axis and their corresponding points on y axis in this format (x,y).
point 1 (10,5) and point 2 (20,10)
Gradient = (y2-y1) /(x2-x1)
= (10-5)/(20-10)
=5/10
Gradient (m)=1/2

Now that you know gradient, solve using either of the points you picked as shown below: Note pick a third in letters not numbers example point 3 (x,y)

Lets use point 1 (10,5) and point 3 (x,y).
Gradient = (y-5)/(x-10) : Note we already know gradient is 1/2
so, 1/2 = (y-5) / (x-10)
Rearranging and simplifying: y-5 = (1/2)(x-10)
y-5=(1/2 x) - 5
Add 5 to both sides
y-5+5=(1/2x)-5+5
y=1/2x+0

Final answer y=1/2x or y=0.5x

Find the equation of the line.<br> Use exact numbers.

Vedmedyk [2.9K]

Answer:

8 = 3x - 4y

or y = (3/4)x - 2

Step-by-step explanation:

(4,1) and (0, -2) are the two points I see.

slope = (1 -(-2))/(4 - 0) = 3/4

y-int: -2

y = (3/4)x - 2

or 2 = (3/4)x - y

8 = 3x - 4y

DJ Mykel is making a playlist for a radio show; he is trying to decide what 14 songs to play and in what order they should be pl

konstantin123 [22]

Answer:

5878600 different playlists.

Step-by-step explanation:

Since we require 14 songs for the playlist and there are 7 hip-hop, 5 jazz, 7 pop, and 8 blues songs, and DJ Mykel wants to play no more than 3 hip-hop songs, the number of ways in which he can combine the 7 hip-hop songs to play no more than 3 is ⁷C₃ = 7!/4!3!.

Now, since we have 3 songs already selected, we are left with 14 - 3 = 11 songs to select.

Since we have selected the 3 hip-hop songs, we are left with 5 jazz, 7 pop, and 8 blues songs which sum to a total of 20 songs.

So, we have 20 songs to select in 11 ways which is ²⁰C₁₁ = 20!/(20 - 11)!11! = 20!/9!11!

So, the number of different playlists that can be formed is thus

⁷C₃ × ²⁰C₁₁ = 7!/4!3!.× 20!/9!11!

= 35 × 167960

= 5878600 different playlists.

What are the angle measures of X and Z?

anyanavicka [17]

Answer:

m∠Z=146

m∠X=34

Step-by-step explanation:

Since this is an Isosceles Trapezoid, we can assume that m∠Z=m∠Y, because an isosceles trapezoid has two pairs of congruent angles, therefore m∠Z=146.

Since angle Y and Angle X are same side interior and line ZY║WX, we can assume that m∠X+m∠Y=180. Substitute values:

$146+X=180\\Y=34$
