Answer:
Step-by-step explanation:
The direct proportion equation is ...
y = kx
where k is the constant of proportionality. Here, you're told k=-2, so the equation is ...
y = -2x
For x=8, the value of y is ...
y = -2(8) = -16 . . . . . do the multiplication
For y = -20, the value of x is ...
-20 = -2x
10 = x . . . . . . . . . divide both sides by -2
I hope this helps you
(-)×(-)=+
-(-16)
+16
To simplify this expression, you have to remember that when
a number or a variable is raised to the negative exponent you have to
reciprocate the number. In this expression, c^-8 will be reciprocated so it
will become part of the numerator. Therefore, the final answer would be
12c^8/d^2.
