The answer is 0.5 because 0.5 is 1/2 in fraction form.
The awnser is 148 You just need to add the two to get the original price
B and A because they both pass through the origin. direct variations have no b value so they can not pass through any numbers in the y axis except for the origin. Hope this helps!
In order to solve the equation we should take the natural logarithm of both sides of the equation (the goal is to remove the variable from the exponent)<span>ln<span>(4^(2x+1))</span>=ln<span>(3^(<span>x−2)</span><span>)
(2x+1)ln(4)=(x-2)ln(3)
2x*ln(4)+ln(4)=xln(3)-2ln(3)
</span></span></span>2x*ln(4)-xln(3)=-ln(4)-2ln(3)
x(2ln(4)-ln(3))=-ln(4)-2ln(3)
x=-ln(4)-2ln(3)/(2ln(4)-ln(3))
