Question

determine whether each value makes the equation true or false.

1. ( x - 3 geq 0 )

if ( x = 2 )
if ( x = 3 )
if ( x = 4 )

1. ( 15 + b > 21 )

if ( b = 4 )
if ( b = 6 )
if ( b = 8 )

Explanation:

Step1: Substitute x=2 into inequality

$2 - 3 \geq 0$ → $-1 \geq 0$

Step2: Substitute x=3 into inequality

$3 - 3 \geq 0$ → $0 \geq 0$

Step3: Substitute x=4 into inequality

$4 - 3 \geq 0$ → $1 \geq 0$

Step4: Substitute b=4 into inequality

$15 + 4 > 21$ → $19 > 21$

Step5: Substitute b=6 into inequality

$15 + 6 > 21$ → $21 > 21$

Step6: Substitute b=8 into inequality

$15 + 8 > 21$ → $23 > 21$

Answer:

1. If $x=2$: False

If $x=3$: True
If $x=4$: True

1. If $b=4$: False

If $b=6$: False
If $b=8$: True
