To solve the compound inequality:
x/4 < -1 and x + 7 > -2
Let's solve each inequality separately and then find the intersection of their solutions.
1) x/4 < -1
Multiply both sides of the inequality by 4 (since 4 is positive and we don't need to flip the inequality sign):
x < -4
2) x + 7 > -2
Subtract 7 from both sides of the inequality:
x > -9
Now let's find the intersection of these two solutions. We want values of x that satisfy both inequalities.
The solutions to the compound inequality are x < -4 and x > -9.
Graphically on a number line:
--------------(-9)======(-4)-----------------
The shaded area represents the values of x that satisfy both inequalities.
The correct answer is d) -8 < x < -4.
Solve and graph the compound inequality on a number line x/4 < -1 and x + 7 > -2 Select the correct answer from the following
a) x > -6
b) All real numbers
c) -6 < x < 6
d) - 8 < x < -4
