Answer: 30+x+y
Step-by-step explanation:
- Commutative Property of Addition : a+b= b+a , where a and b are any arbitrary numbers.
Given : Number of CDs sold by friend on first day = 14
Number of CDs sold by friend on next day = x
Total CDs sold by friend = 14 +x
Number of CDs sold by you on first day = 16
Number of CDs sold by you on next day = y
Total CDs sold by you = 16+y
The expression that shows the total number of CDs sold both days =
Total CDs sold by friend + Total CDs sold by you
= 14 +x+ 16+y
= 14 +(x+ 16)+y
= 14 +(16+x)+y [By Commutative Property of Addition.]
= 14+16+x+y
= 30+x+y
Hence, the expression that shows the total number of CDs sold both days :
30+x+y
X-3y because 8x+2x-9x is x

Answer
14
Step-by-step explanation:
x=0 y=7 x=-1.25 y=0
So this is x intercept and y intercept so if we do 1 by 1 then the y intercept would equal to 7 and the x intercept would equal to -1.25.
