which inequality is true when x = 4? A. 3 - 2x < -5. B. 1 - 4x > -14. C. -5 - 3x < 10. D. -4 + 5x > 18
Let's substitute x = 4 into each inequality.
A. 3 - 2(4) < -5
3 - 8 < -5
-5 < -5 (This is false)
B. 1 - 4(4) > -14
1 - 16 > -14
-15 > -14 (This is true)
C. -5 - 3(4) < 10
-5 - 12 < 10
-17 < 10 (This is true)
D. -4 + 5(4) > 18
-4 + 20 > 18
16 > 18 (This is false)
Therefore, the inequalities that are true when x = 4 are B and C. So, the answer is:
B. 1 - 4x > -14
C. -5 - 3x < 10
