Think: "isolate x." Also, remember that when you mult. or div. terms in an inequality by a neg. # you must reverse the direction of the inequality symbol.
−4x−8>−20 becomes <span>4x + 8<20</span> after dividing the original by -1 and then reversing the direction of the inequality symbol.
Now isolate x, first by subtract 8 from both sides and then dividing the result by 4:
4x + 8 < 20
- 8 < -8
----------------------
4x < 12
Divide both sides by 4: x < 3 (answer)

Graph attached. To graph by hand find the values at 1 and 3 by plugging it into the original function and drawing a line between the two.
2(1)-2 = 0 Point (1,0)
2(3)-2 = 4 Point (3,4)
Answer:
295= 210+X
Step-by-step explanation:
If she has a total of 295 dollars deposited and she had 210 before then you could just subtract 295-210 to find how much she deposited. The answer would be that she deposited 85 dollars in her savings account and the equation is listed above.
