B. Evaluate the given expression using the given values of x in the table.
Answer:
1) 3x + 6
-1 → 3
0 → 6
1 → 9
2) 5x-2
-1 → -7
0 → -2
1 → 3
Solution:
#BY SUBSTITUTION METHOD#
1) 3x + 6
→ TO FIND THE VALUE OF (-1) ←
= 3x + 6
= 3(-1) + 6
= -3 + 6
= 3
→ TO FIND THE VALUE OF (0) ←
= 3x + 6
= 3(0) + 6
= 0 + 6
= 6
→ TO FIND THE VALUE OF (1) ←
= 3x + 6
= 3(1) + 6
= 3 + 6
= 9
2) 5x-2
→ TO FIND THE VALUE OF (-1) ←
= 5x - 2
= 5(-1) - 2
= (-5) - 2
= -7
→ TO FIND THE VALUE OF (0) ←
= 5x - 2
= 5(0) - 2
= (0) - 2
= -2
→ TO FIND THE VALUE OF (1) ←
= 5x - 2
= 5(1) - 2
= (5) - 2
= 3
