Answer:

Step-by-step explanation:
We are going to use the identity
because this identities right hand side matches your expression where
and
.
So we have that
is equal to
.
That's the easily recognizable factored form of
the difference between two squares. Before
factoring, it was
x² - 16 .

Answer:
y = -2x + 3
Step-by-step explanation:
We can write an equation in slope-intercept form. Use the slope formula to find the rate of change in the table:

Plug in values from the table:

Simplify:
m = -2 (rate of change)
Use a point from the table (-2, 7) and the slope to solve for the equation for the linear function:
7 = -2(-2) + b
7 = 4 + b
7 -4 = b
b = 3
Rewrite:
y = -2x + 3 is the equation for the linear function.
Answer:

Step-by-step explanation:
Given
--- Average
--- Average
Required
Determine the overall average
Represent the sum of the first three with x.
So:

Solve for x


Represent the sum of the next seven with y.
So:

Solve for y


The overall average is calculated as thus:
