The sum of 7 and three times a number is at least 13
Yuki888 [10]

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.

I need help ASAP on this algebra question
Misha Larkins [42]

Answer:

As x goes to negative infinity, g(x) goes to zero.

As x goes to positive infinity, g(x) goes to zero.

(So the answer is the second option)

Step-by-step explanation:

We have the function g(x)=\frac{1}{x^2}

First, let's look at what happens when we input smaller and smaller numbers

g(-10)=\frac{1}{100} \\\\g(-100)=\frac{1}{10000}

As we can see, as we input smaller and smaller numbers, the answer gets smaller.

Eventually, these fractions will be so small that they will get closer and closer to zero.

This same thing applies to larger and larger numbers, so the end behavior of each side will both be zero.
