Answer:
The given expression
after the negative exponents have been eliminated becomes 
Step-by-step explanation:
Given expression 
We have to write expression after the negative exponents have been eliminated and a ≠ 0 and b ≠ 0.
Consider the given expression
We have to eliminate the negative exponents,
Using property of exponents,
we have ,

Substitute, we get,
becomes 
Thus, the given expression
after the negative exponents have been eliminated becomes 
The answer 48 with a remainder of 4. Hope this works.
Answer:
y = - 4x + 16
Step-by-step explanation:
Assuming you require the equation of the line passing through the points.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 4) and (x₂, y₂ ) = (5, - 4)
m =
=
= - 4, thus
y = - 4x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 4), then
4 = - 12 + c ⇒ c = 4 + 12 = 16
y = - 4x + 16 ← equation of line
