X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
Answer: m = -4 / 2 = -2 / 1 = -2
Slope (m) = -2
Step-by-step explanation:
Answer: 210
percent * base = amount
.6 * base = 126
base = 126/.6
x = 210
Step-by-step explanation:

<span>You have the following inequality given in the problem shown above:
(x^2-1)/(x^2+5x+4)</span>≤<span>0
1. To solve it, you must factor it and then you must make the study of the signs.
2. Once you do the proccedure mentioned above, you obtain the following solutions:
-4<x<-1 -1<x</span>
