4x+8

I am interpreting this as: Find the derivative of: y=((2x+5)8+4x)3 To find the derivative (y'), the chain rule must be applied. The "outermost" function of this compound function is t3 (t being an arbitrary quantity). The derivative of t3 is 3t2 * dt, where "dt" is the derivative of the quantity "t". Applying this, we arrive at a working definition of y': y' = 3((2x+5)8+4x)2(derivative of (2x+5)8+4x) The derivative of (2x+5)8+4x is found using basic derivative definitions and the chain rule again: 8(2x+5)7(2)+4 = 16(2x+5)7+4 So now we can write y' again: y'= 3((2x+5)8+4x)2(16(2x+5)7+4) = 48((2x+5)8+4x)2((2x+5)7+4) This can be further simplified, but this is an arduous process. If you need further simplification, feel free to contact me via private message.

If: 4x+(-12) = 8 then 4x = 20 and x = 5

8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0

-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3

4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x

3x-8

5x + 3 - 4 + 4x = 9x -1

If the equation is y = 4x + 8, then the standard form is 4x - y + 8 = 0

8 + 4x - x = 8 3x = 8 - 8 x = 0

25

9x + 8 = 4x + 23Subtract 8 from both sides9x = 4x + 15Subtract 4x from both sides5x = 15Divide both sides by 5x = 3

4x+8

collect like terms and you get 4x + 5x + 8 - 3 ie 9x +5

4x+5=7x-8 the ansewr is 3.25

x=5

Lets simplify the above given equation : -8 plus 6(-x - 3) plus 4x simplified as : -8-6x -18 +4x =-2x -26 . =-2(x+13).

7x+8

2x - 5 - 4x + 8= 2x - 4x - 5 + 8= -2x + 3

-6x-6 -or- -6(x+1)

This would simplify as 4x-5

4x + 8

8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.

Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
