Answer:
They added 8 to each side, --8 is +8 so we need to subtract - from each side not add 8 to each side
Step-by-step explanation:
We have a slope and a point
We can use point slope form
y-y1 = m(x-x1)
y--8 = -6(x-2)
y+8 = -6(x-2)
Distribute the -6
y+8 = -6x+12
Subtract 8 from each side
ERROR in the students work
They added 8 to each side, --8 is +8 so we need to subtract - from each side not add 8 to each side
y+8-8 = -6x+12-8
y = -6x+4
It would be A, but it ultimately matters what formula you are using.
Answer:
y^4
Step-by-step explanation:
Exponential laws state that you subtract the exponents when dividing (5-3=2) and you add when multiplying (2x2)
giving you y^4
Answer:
Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function B has a greater rate of
Step-by-step explanation:
Function A:

Function B:

Required
Which has a greater rate of change
The rate of change of function A is calculated as thus:

Where:


So, we have:



For function B
The general function is:

Where
m is the rate of change
By comparing
to 

So, we have that:
Function A has a rate of -5; function B has a rate of -4.5.
By comparison: -4.5 is greater than 5
Hence, function B has a greater rate.
