-2-2x≤2
To solve an inequality, it's just like an equation, first add 2 to both sides to get
-2x≤4
Divide both sides by -2to get
x≥-2
When you divide by a negative number, you flip the sign.
Your solution is x≥-2.
Hope this helped!

Answer:
3. 2n - 4 = 7(n + 8)
Step-by-step explanation:
Two times a number is 2n. Four less than 2n is (2n-4). The sum of a number and 8 is (n+8). Seven times that sum is 7(n+8). The statement says these values are equal:
2n -4 = 7(n +8)
Answer:
see explanation
Step-by-step explanation:
Given a quadratic function in standard form y = ax² + bx + c ( a ≠ 0)
• If a > 0 the the graph has a minimum value ∪
• If a < 0 then the graph has a maximum value ∩
Thus y = - 3x² + 1 ← has a maximum value and
y = x² ← has a minimum value
