1
Step-by-step explanation:
Answer:
f(x)-values
decreased by 4
(4,87)
Step-by-step explanation:
The table shows the exponential growth function
substitute some values to find 
Subtract these equations:
Divide them:
Then
Hence,
Therefore, the parent function is
If this function would be translated 4 units down, its expression will be
This means that f(x)-values decreased by 4.
Then the table for translated function is
The graph of translated function passes through the point (4,87)
Answer:
y=-2x+3
Step-by-step explanation:
2x−y+4=0
y=-2x-4
Slope =-2=m (because line is parallel, slope is the same)
(-1,5)....x1=-1, y1 =5
y-y1 =m(x-x1)
y-5=-2(x-(-1))
y-5=-2(x+1)
y-5=-2x-2
y=-2x-2+5
y=-2x+3
Answer:
The number of slices of salami and the number of calories are not proportional. Step-by-step explanation: we know that. A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or . In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
