Answer:
7 + 3x ≥ 13
Step-by-step explanation:
The best way to write this is to truly understand what each of the terms mean. The sum means that multiple terms are added together, which means that 7 and 3 times a number will be added together.
Next, the term three times a number just means 3x. So as of now, we have 7 and 3x being added together.
Finally, the term at least 13 means that the 7 + 3x is greater than or equal to 13. Once everything is put together, you get a final inequality of 7 + 3x ≥ 13.
A number times 1 always equals itself, so: 4×1 = 4, OR 2×2 = 4
1- 13 or -13 (B)
2- -5 < y < -3 (A)
3- t = 6 or -6 (B)
Hope this helps you =)
Good evening
Answer:

Step-by-step explanation:
g(x) = -20
⇔
3x-1 = -20
⇔
3x = -20 + 1
⇔
3x = -19
⇔
x = -19/3
