Answer:
The weight of the baby is 25 lbs. 
The weight of the dog is 10 lbs 
Total weight = 170 lbs 
Your weight = 135 lbs
Step-by-step explanation:
The total weight is 170 lbs which is shown in the picture.
Suppose the weight of the baby is x lbs . The weight of the dog is 60 % less than x 
so x -  0.6 x lbs = 0.4 x is the weight of the dog
 And suppose your weight is y lbs.
x+ 0.4x  + y= 170
1.4x+ y= 170
y = 170-1.4x ------1
The sum of your weight , the baby and dog is 100 lbs more than the two combined.
y- 100 = 1.4x
  x +0.4x + 100= y
1.4x+100= y----2
Putting 1 in 2
1.4x+100=170-1.4x 
1.4x+ 1.4x = 170- 100
2.8x= 70
x= 25lbs
The weight of the baby is 25 lbs. 
The weight of the dog is 4.4x= 0.4 (25)= 10 lbs 
Total weight = 170 lbs 
Your weight = total weight less baby's weight less dog's weight
                     = 170- 25- 10= 135 lbs

Answer:
Every input can have only one output. But an output can have multiple inputs. Basically an x coordinate can have the same y coordinate as another ordered pair but not the same x coordinate. This is why d) does not represent a function.
Step-by-step explanation:
(4,-2)
(4,2)
4 is mentioned twice and every input( x value) can have only one output ( y-value)
