what are the explicit equation and domain for an arithmetic sequence with a first term at eight in the second term of 5
olga nikolaevna [1]

Answer:

f(n) = 8 -  3f(n-1)

d : {  8 >= x }

Step-by-step explanation:

Basically we know 8 is the first term, so we subtract 3 to get 5 which is the second term. Then we know d = -3. Now we that we established the formula, let's make a domain. We know x can never be greater than 8 so x is always less than or equal to 8.

Eli has $640 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
Irina18 [472]

Answer:

Step-by-step explanation:

First of all we have to discover how much he spent.

356.89 + 2(16.70) + 27.47 = $417.76

Now we have to find how much money he saved

640 - 417.76 = $222.24

the total cost of biking outfits must be eqaua or less than $222.24..

We know the price of a single outift so we can write this inequality:

74.08o ≤ 222.24

we can find o by dividing the two members of the inequality:

o ≤ 222.24/74.08  = 3

o≤ 3

this mean that he can buy 1, 2 or 3 outfits

What is the value of a if y=a(x-3)^2-1
Allisa [31]

The value of the equation for "a" in terms of x and y is (y+1)/(x-3)²

Step-by-step explanation:

The equation is a classic example of a binomial equation in 2 variables and one constant.

Given- y=a(x-3)²-1

Transferring 1 to the left-hand side

y+1=a(x-3)²

We can opt for various method from now on like we can divide both the sides by (x-3)² or we can possibly transfer (x-3)² to the left-hand side to get the value of "a" in terms of "x" and "y"

∴ Opting for the first method, we get

(y+1)/(x-3)²=a

Thus the required value of "a" in terms of the variable "x" and "y" is as follows-

a= (y+1)/(x-3)²
