10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3
x/10x = 1/10 or 0.1
0
x2-10x = 0 x(x-10) = 0 x = 0 or x = 10
x2 + 9 = 10x x2 - 10x + 9 = 0. (x - 9)(x - 1) = 0. Therefore, x = 1 or 9.
-10x = x-33 -10x-x = -33 -11x = -33 x = 11
Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3
x/10x = 1/10 or 0.1
0
10x=x 9x=0 x=0
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
( x^2 + 10x )^2 = ( x^2 + 10 x) ( x^2 + 10x ) = x^4 + 10x^3 + 10x^3 + 100x^2 = x^4 + 20x^3 + 100x^2 <----------------
-8 + 10x = 18 10x = 18+8 10x = 26 x = 26/10 x = 2.6
10x-1=35 is equal to 10x-1+1=35+1, or 10x=36 10x=36 is equal to 10x/10=36/10, or x=3.6
x2+10x-24 = (x-2)(x+12) when factored
The derivative of 10x is 10. This is irrespective of the value of x.
