Example...
4^x = 16
log(4^x) = log(16)
x*log(4) = log(16)
x = log(16) / log(4)
This inequality has NO SOLUTION:
PROOF:
3x + 1 < 2x - 2 < 5x +7
1st let's analyze the 1st inequality: 3x+1<2x-2
3x-2x <-2-1 Then x <-3
2nd let's analyze the 2nd inequality: 2x-2 < 5x+7
2x-5x < 7+2 Then -3x<9 OR 3x > - 9 and x> - 3
In the 1st we have x <-3 in the 2nd we have x > - 3 which is impossible
Point slope form is an equation to graph lines.
$100?
100+80=180
180-23=157
157-90=67
Hope this helps !
