Unlock StepbyStep y 2x =1, 2y x = 4 Natural Language Math Input NEW Use textbook math notation to enter your math Try it × Extended Keyboard Examples. It is clear that the lines x2y3=0 & x2y7 are parallel hence the forth line (side of square) must be parallel to third line 2xy4=0 Hence, let the forth line 2xyc=0 having slope 2 How do.

Answer (1 of 4) Given, 2^x = 4^y = 8^z ⇒ 2^x = 2^(2y) = 2^(3z) Compare power with same base 2 therefore, x = 2y = 3z (1) xyz = 2 (Given) x(x/2.

There are certain tricks that will be used here (1) Equation of any line passing through two curves ( S and S’ ) can be written as β (S) γ (S’ ) = 0, where β and γ are arbitrary constants. Solving for the second variable will give you a solid numerical value You can also solve this system of equations using the addition method, which I’ll illustrate below 2x 2y = 4 4x2y = 8 Combine the two equ.  In this case, write x − 2y = 2 as x = 2 2y Note that we had to add 2y on both sides of the equation to get that result Substitute the value of x into the other equation so that you get an expression in terms of y So y2 − x2 = 2x 4 becomes y2 −(2 2y)2 = 2(2 2y) 4 ⇒ y2 − (4 8y 4y2) = 4 4y 4 ⇒ −3y2 − 4 − 8y.

Answer (1 of 3) First one uses the result that a^2b^2=(ab)(ab) In this case we have a=x2y, b=2(2xy)=4x2y So we get (x2y)^2(2(2xy))^2=(x2y(4x2y))(x2y4x2y) or (3x4y)(5x) In this case use the factorisation which is already given This saves a lot of work.
