So just try it for x=1 how many will get for y
y+3=2(x-1) for x = 1 will get y+3 =2(1-1) so y+3=2*0 so y+3=0 so y=-3
x=1
y=-3 so choice A.(1,-3) is right sure
hope this will help you
A. Is 41 degrees, B. Is 44 degrees
700x + 375(27 - x) = 15000
Solve for x
X=15 business class
Economy class 27-15=12
Answer:
444 adult ticket
763 student ticket
Step-by-step explanation:
let a = number of adult ticket
let s = number of student ticket
s+a=1207
5a+s=2983
get s by itself in the 1st equation so you can plug it into the 2nd
s+a=1207
-a -a
s=1207-a
5a+(1207-a)=2983
solve for a
4a+1207=2983
-1207 -1207
4a= 1776
444
this is adult ticket amount
subtract this from 1207 to get student amount
1207-444=763
