Answer:
Step-by-step explanation:
Add or subtract multiples of 360° to find coterminal angles.
<u>Positive</u>
75° +360° = 435°
75° +2×360° = 795°
<u>Negative</u>
75° -360° = -285°
75° -2×360° = -645°
Answer: 1/4 OR 1/8
Step-by-step explanation:
the first coin can be heads which has a 1/2 chance of happening and the other coin also has a chance to get tails which is 1/2
if you add the 1/2 and the other 1/2 you can get 1/4 OR 1/8
Answer:
X > (greater than or equal to) -7
Step-by-step explanation:
3x + 15 > -6
3x > -21 (subtract 15 from both sides)
X > -7 (divide both sides by 3)
Answer:
-8 ≤ y ≤ 8
Step-by-step explanation:
Subtract 7 from the first one:
y ≥ -8
Subtract 3 from the second one, then multiply by 4.
y/4 ≤ 2
y ≤ 8
Now, you can write these as a compound inequality:
-8 ≤ y ≤ 8

<em>Additional comment</em>
You basically solve these the same way you would an equation. The only difference is that multiplying or dividing by a negative number will reverse the inequality symbol:
2 > 1
-2 < -1 . . . . . multiplied above by -1.
