So.. hmm check the picture below
now, to know where A and B are, that occurs when the parabolic equation equates the linear one
thus

now, running that on the quadratic formula, you end up with the values of 3.00402497440839842242 and 0.77175977895483027713
thus B rounded up is 3.004 and A rounded up is 0.7718
what's the "y" value for B?, well, you can use either the linear or quadratic equation for that, let's use the quadratic one

$\implies 2^{2x}-2\cdot5^{2x}-(2^x)(5^x)>0$
let $2^x=a$ and $5^x=b$
So, $a^2-2b^2-ab>0$
divide by $b^2$, ($b^2>0$)
$\implies \left(\frac ab\right)^2-\left(\frac ab\right) -2>0$
this is a quadratic, in $\left(\frac ab\right)$, let it be $x$
So, $x^2-x-2>0$
Can you simplify it now?
I believe the answer is ]2 \frac{39}{50}
Answer:
Step-by-step explanation:
28x-12y=16 and -6x-12y=3
or
14x-6y=4 and -14-28y=1
or
-28x-12y=16 and 28x-56y=14
Answer:
561 1/8 inches cubed
Step-by-step explanation:
The volume of a rectangular prism (the 3D shape of the pizza box) is denoted by:
, where l is the length, w is the width, and h is the height.
Here, the length is "sixteen and three fourths inches" =
, the width is "sixteen and three fourths inches" =
, and the height is 2 inches. Plug these into the equation:


To make this easier, turn the mixed numbers into improper fractions:
. Now, we have:
inches cubed.
Hope this helps!
