Y = 360x + 120.
The y-intercept would be at (0, 120), as at year 0 or x=0, the weight is 120 kg.
If it increases every year by 360 kg, it would be noted in how many years it has been by 360x.
Answer and Explanation
1. Males taking geometry
Explanation: Find 19% of 30 to find answer
2. B- Between 40-60 minutes
Explanation: Measure the difference between the intervals
3. B is correct.
Explanation: From the graph the actual heart rate=150=150
but calculated heart rate from best fit line=148=148
Difference between actual and calculated=150-148=2=150−148=2
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
