Answer:
x + 2y - 5 = 0
Step-by-step explanation:
We can see that , the graph passes through (0,2.5) and (5,0) . Therefore the ,
- x intercept is 5
- y intercept is 2.5
We can use the intercept form of equation as ,
=> x/a + y/b = 1
=> x/5 + y/2.5 = 1
=> x + 2y/5 = 1
=> x + 2y = 5
=> x + 2y -5 = 0 .
This equation can be verified by plotting the graph .[ Refer to attachment ]

He has to be 5 since 5×3=15 and each year he turns one year older so yea
You need to write this question out in algebra form first. X + x + 1 + x + 2 = 72 than you add the like terms
3x + 3 = 72 ... 3x=69 ... x=69/3 ... x=23. So we have now found x now you just add 1 to x and get 24 and you add 2 to x you will get 25.
Add 23 + 24 + 25 together you will get 72
