Answer:
B. -7 is less than or equal to x, which is less than 12
Step-by-step explanation:
-7x -50 </= -1
add 50 to both sides
-7x <= 49
divide both sides by -7. When you divide and inequality by a negative number, the direction of the inequality changes.
x >/= -7
---------------------------------
-6x + 70 > -2
subtract 70 from both sides
-6x > -72
divide both sides by -6, flipping the inequality sign
x < 12
------------------------------
Since the problem says *and*, we can say x is equal than or greater to -7 and less than 12
-7 </= x < 12
