The answer would be:
-7sqrt(6x)/4x^3
Count by 1s or 5s. Write the first five numbers you would count, starting at 15.Starting by 1s
1. 16
2. 17
3. 18
4. 19
5. 20
Next is by 5s
1. 20
2. 25
3. 30
4. 35
5. 40
-10 ≥ 2x + 14
-24 ≥ 2x [subtract 14 from both sides]
2x ≤ -24 [read right to left]
x ≤ -12 [divide both sides by 2]
Check:
Let x = -13 (It is ≥ -12)
Is this true: -10 ≥ 2(-13) + 14 ?
-10 ≥ -26 + 14 ?
-10 ≥ -14 ?yes
Let x = -11 (it is not ≥ -12)
Is this false:: -10 ≥ 2(-11) + 14 ?
-10 ≥ -22 + 14 ?
-10 ≥ -8 ?yes
