The x and y coordinates swap places. Thus, the point (a,b) becomes (b, a).

The transformation from y = f(x) to y = f(x - 4) - 2

x8-1

becomes

(x4 + 1) (x4 - 1) - perfect square

and then

(x4 + 1) (x2 - 1)(x2 + 1) - perfect square again.

and then

(x4 + 1)(x2 + 1)(x + 1)(x - 1) - perfect square again

There is no equation nor inequality in the question.

Y = X + 1

The graph is a straight line, with [ slope = 1 ], and passing through the point [ Y = 1 ] on the Y-axis.

x=7 and y=4

x = 4 - 6 t2

Speed = (dx/dt) = - 12 t

Speed = 0 when t = 0

x(0) = 4

The particle stops at [ t = 0 ], located at [ x = 4 ].

The physical reality is: The particle started at [ x = 4 ], and once it started moving, it never stopped.

x2 +3 = 0

x2 = -3


so x must be the root of -3


Unfortunately, you cannot solve this question without the use of imaginary numbers

30 x 0

First determine whether the equation is a direct variation or a regular equation.

1. Direct Variations in inverse can be solved in the following.

y=6x switch y with x ---> x=6y solve for y

2.Regular equations in inverse can be solved in the following.

y=-2x-10 switch y with x----> x=-2y-10 add 10---> x+10=2y solve for y

hindi ko nga alam ehh.................................................................

X= x

x*x1/2= x3/2

Derivative = 3/2 * x1/2

If this is school work, the solution is as follows:

Treat the inequality as an equality and graph the relevant line (straight or curved). Set both variables equal to 0 and find out whether or not the inequality at (0,0) is true. If the inequality is false, reject (shade out) all of the plane on the side of the line that contains the origin while if it is true, reject the part of the plane beyond the line. The unshaded part is the valid (or feasible) region.

I assume you mean 3x-2=5

To solve this (to find x) you need to make it so that on 1 side you have ?x and the other, an equation.

To make 3x-2 equal 3x, you need to add 2, once you have done that, that side equals 2 more than the other side so you need to add 2 to 5.

The equation is now 3x-2+2=5+2

OR 3x=7

Divide 7 by 3 to get x.

7/3=2.33333..... (the 3 reccures)

Hope this helps :)

4x - .5 = 8

Add 0.5 to both sides: 4x = 8.5

divide both sides by 4: x = 2.125

Equation: 20/x^2 -1/x = 1

Multiply all terms by x^2: 20 -x = x^2

Transposing terms: 20 -x -x^2 = 0

Factorizing: (x-4)(-x-5) = 0 => x = 4 or x = -5

Therefore: x = 4 or x = -5

An asymptote is a line or curve that approaches a given curve arbitrarily closely.
