Answer:
They have opposite signs. if x=16 then y should be -16 for their sum to be zero.
Answer:
Third option: The graph moves left 18 units.
Step-by-step explanation:
Some transformations for a function f(x) are shown below:
If
, the function is shifted up "k" units.
If
, the function is shifted down "k" units.
If
, the function is shifted left "k" units.
If
, the function is shifted right "k" units.
In this case, we can observe that graph of
is changed to
Since:

We can conclude that the function
is shifted left 18 units to get the function
.
Answer:
a) y= 8x+90 b) 154 pounds
Step-by-step explanation:
a) 90 will be the initial value (b) and 8 will be the slope (m)
this gives the linear function :
y = 8x + 90
b) to find his weight after 8 weeks plug in x=8
y= 64+90
y=154
154 pounds
