I don't need to break "4 x 5" apart, because just as it is, "4 x 5" is a multiplication fact

that I know. If you start doing your own work, you'll know it too, in almost no time at all.

I assume you mean this system.

Y - 4X = 10
Y = 2X - 6

You are given Y, so insert into top equation to find X.

(2X - 6) - 4X = 10

- 2X - 6 = 10

-2X = 16

X = - 8
===========find Y, bottom equation

Y = 2(- 8) - 6

Y = - 16 - 6

Y = - 22
============ You try checking it.

Log(y) can be any number, positive or negative, no limits.

It all depends on the value of 'y'.

A transversal is simply a line that passes through two or more other lines . (the lines should be in the same plane) Transversals are important becasue if a transverals passes through or intersects two parallel lines we get some special angle congruences. The alternate interior angles are on opposite sides of the transversal line and inside the lines being transversed. Alternate exterior angles are on opposite sides of the transferal line and outside the lines being transversed. The alternate interior and alternate exterior angles are congruent if the lines being crossed by the transversal are parallel ( NOT to each other, the two alternate interiors are congruent and the two alternate exteriors are congruent.

'y' can be anything you want it to be, and 'wz' will still be 46.

1,565 = x5

1,5651/5 = (x5)1/5

1,5651/5 = x5/5

1,5651/5 = x

4.3541 = x

This is the equation of a line in which the slope is 1 and the y-intercept is -4.

100 x 400 is equal to 40,000

3x + 4 = -11

Subtract 4 from both sides: 3x = -15

Divide both sides by 3: x = -5

d/dx cosx=-sin x

52 = 2x + (6x +4)

52 = 2x + 6x + 4 (can skip this step)

52 = 8x + 4

52 - 4 = 8x

48 = 8x

48/8 = x (can skip this step)

6 = x

15 - 2y = 3y

Add 2y to each side to get:

15 = 5y

Divide both sides by 5 to get:

y = 3

Dxdx^(20)

Combine all similar variables in the expression.
Dxdx^(20)=dDx^(21)

To find the derivative of dx^(21)D, multiply the base (D) by the exponent (1), then subtract 1 from the exponent (1-1=0). Since the exponent is now 0, D is eliminated from the term.
Dxdx^(20)=dx^(21)

The derivative of Dxdx^(20) is dx^(21).
dx^(21)

d/dx(in x)

= 1/x

The proof is very confusing, so I just commit this to memory.

It's one of the simplest linear equations in 'x' that can be written.

Its solution is [ x = -5 ].
