Solve for a.
4/a+4 =-1/a+9

Solve For A.4/a+4 =-1/a+9

Answers

Answer 1

Answer:

a = -8

Step-by-step explanation:

you can solve this proportion by cross-multiplying:

4(a + 9) = -1(a + 4)

now distribute to eliminate parentheses

4a + 36 = -1a - 4

5a + 36 = -4

5a = -40

a = -8

The value of r of the geometric series is 4/5.

What is geometric series?

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The nth term of a geometric progression is expressed as

Tₙ = arⁿ⁻¹

Where a is the first term, r is the common ratio

Given the formula for the geometric series expressed as

[tex]_3\\\sum{1.3(0.8)^n^-^1}\\n=1[/tex]

Comparing both equations

rⁿ⁻¹  =  (0.8)ⁿ⁻¹

r = 0.8

r = 8/10

r = 4/5

Hence, the common ratio is 4/5.

Identify the writing problem(s) in the following paragraph: The U. S. government defines poverty using an income-based threshold created in the early 1960s, which set the poverty level at 3 times the yearly cost of a basic food budget. Except for adjustments for inflation, it has remained unchanged since it was established despite the fact that today's families spend more on housing, child care, and health care than food. Social service workers spend much of their time trying to help families in need patch together a network of resources to meet their basic needs. Because the level of public assistance has not kept pace with other costs, this means they spend a greater proportion of their income on basic necessities that are not accounted for in the poverty equation. Further, it fails to account for regional differences in costs or receipt of other benefits such as Medicaid and Food Stamps.A. The information is poorly organizedB.
