Answer:

<em>(f-g)(x) = - x² + 2 x + 8</em>

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given f(x) = 2 x +1

          g(x) = x² - 7

(f-g)(x) = f(x) - g(x)

          = (2 x + 1) - ( x² -7)

         = - x² + 2 x + 1 + 7

       =  - x² + 2 x + 8

<em>(f-g)(x) = - x² + 2 x + 8     </em>

A certain plant grows 134 inches every week. How long will it take the plant to grow 714 inches?
Bond [772]

The information we know:

1 week = 134 inches

x = 714

What I did was, I divided 714 by 134 to find the amount of weeks:

714/134 = 5.3

So, from the equation, basically, in 6 weeks (actually 5.3 weeks) the plant will grow 714 inches long

(Worth 30 points) What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term
kolbaska11 [484]

Answer:

a_n=5-2(n-1), all integers where n≥1

Step-by-step explanation:

we know that

The explicit equation for an arithmetic sequence is equal to

a_n=a_1+d(n-1)

a_n is the th term

a_1 is the first term

d is the common difference

n is the number of terms

we have

a_1=5\\a_2=3

Remember that

In an Arithmetic Sequence the difference between one term and the next is a constant, and this constant is called the common difference.

To find out the common difference subtract the first term from the second term

d=a_2-a_1=3-5=-2

substitute the given values in the formula

a_n=5-2(n-1)

The domain is all integers for n\geq 1
