Answer:
x = 48
Step-by-step explanation:
Supplementary angles sum to 180°
add the 2 angles and equate to 180
x + 3x - 12 = 180 ( add 12 to both sides )
4x = 192 ( divide both sides by 4 )
x = 48
Y=-1/3x+4
x2-x1/ y2-y1
(0,4)(2,-2)
2-0/-2-4
1/-3
y-intercept is 4
y=-1/3x+4
Answer:
Hello your question has some missing information below is the complete question
answer :
Step-by-step explanation:
Red car and Blue car take up 2 spaces each
Green cars take up 1 space
<u>lets determine the number of ways of filling up the parking spaces</u>
i) First lets assume the last space is filled by Green car then there will be space occupied hence there will be ( n - 1 ) spaces left to be filled in ways
ii) lets assume the last space is filled by either a Red car or a Blue car then there will be parking space occupied hence there will be
( n - 2 ) spaces left to be filled in ways
<u>Hence A closed formula for </u><u> </u>
where : a1 = 1 way , a2 = 3 ways
