Answer:
y=3x+5
Step-by-step explanation:
Point slope equation:
y=mx+b
m-slope, b- is y-intercept
equation given 2 points
y-y1 = m(x-x1)
For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3
y-8 =3(x-1)
arange it in point slope format
y-8=3x-3
y=3x-3+8
y=3x+5
Answer:
14, 96,84
Step-by-step explanation:
8n - 16 + 6n = 180 {Supplementary angles}
<u>8n + 6n</u> -16 = 180
Combine like terms
14n - 16 = 180
Add 16 to both sides
14n = 180 + 16
14n = 196
Divide both sides by 14
n = 196/14
n = 14
8n - 16 = 8*14 - 16 = 112 - 16 = 96
6n = 6 *14 = 84

Answer:The cost of one month of game-play =$20
Step-by-step explanation:
Let the cost of one month of gameplay be x
Then cost of game-play bought by Angie =3x.....(1)
and Then cost of game-play bought by Kenny=4x......(2)
Cost of each software package =$50......(3)
The the total cost =240= sum of costs of software bought by both of them and game-play)=50+50+3x+4x
⇒240=100+7x.......→(by adding like terms)
⇒140=7x⇒x=20.....→( dividing both sides by 7 )
∴the cost of one month of game-play =$20
