Step-by-step explanation:

<em>We change the argument and the value:</em>

<em>Divide both parts of the equation by 2:</em>

<em>The restrictions are imposed on the inverse function by on x:</em>

<em>The restrictions are imposed on the inverse function by on y:</em>

<em>Then the original function is defined on the sets:</em>

<em>The initial function, a parabola, is constrained because of the inverse function; only in this case the functions are reciprocal.</em>
The slope is 3 over 5 or 3/5
The answer would be 4.5 and this is why:
if it is true that <span>PQ=QR=RS
then that means that WY=YX=XV because they are both divided proportionally meaning that all the lengths are equal.
SO 2.25+2.25=4.5</span>
The answer would be 90 cookies
Minus 4x from both sides
x+3=0
minus 3 from both sides
x=-3
