the formula is V=lwh so you would need the length to find it
An equation where j = 3
what is the slope of the line that has the equation 4x+2y=12?
2.3
You cannot solve this single equation. You can either change the subject so that it gives x = 12/y or xy = 12, which is the equation of a rectangular hyperbola.
True
true
It's an hyperbola equation.
This is the curve which shows the unitary elastic demand where the change in quantity demanded equals with the change in price.

You also need an equation for y in order to convert to rectangular form.
The equation to find the volume of a rectangular object is (a) volume equals length times width times height.
true
Assuming that the given demand curve is a rectangular hyperbola, total expenditure (i.e. rectangular area or Q*P) is the same for each point on the length of the curve. Next we use the demand function to determine the total expenditure value as Q=1/P=>Q*P=1, and we have consequently a demand curve of unitary elasticity.
We solved the first equation for 'x': [ x = 2y + 8 ].Then we substituted it for 'x' in the second equation and rearranged: [ y2 + 4y - 12 = 0 ].Solutions of this quadratic equation are: y = 2 and -6. From which x = 12 and -4 .So the straight line intersects the hyperbola at (-4, -6) and at (12, 2) .
No, any equation of the form x2+y2=r2, with r as any number, makes a circle centered at the origin with radius r. Hyperbolas can be of the form xy=k or x2-y2=r2.
