nignag [31]
Slope-intercept form is y=mx+b
we know m is 10 and we have x and y
if you plug in x, y and m and solve for b, like this
y=mx+b
1=10 (7) + b
1=70+b
-69=b
so now we know b is -69. just plug that in
the final answer is y=10x-69

Select the recursive and explicit formula for the Arnold family 2 answers
MariettaO [177]

Answer: The first and last options are correct

Explanation:

The recursive formula is written in terms of the previous term of the sequence. From the information given,

the Arnold's are going to save a nickel on the first day of the month and double the amount each day of the month. Thus, the recursive formula would be

A(n)\text{ = a}_{n\text{ - 1}}\text{ }\times\text{ 2}

where

an - 1 defines a previous term

To write the explicit formula, we would apply the formula for finding the nth term of an arithmetic sequence which is expressed as

An = ar^(n - 1)

where

a is the first term of the sequence

n is the number of terms

r is the common ratio between consecutive terms

Thus,

r = 2 because the amount is doubling each day

n = number of days

a = value of 1 nickel = $0.05

By substituting these values into the formula,

the explicit formula is

A(n) = 0.05(2)^n - 1
