Double
from initial amont of P to final amount of 2P
so

2P=P(1.071)^time
divide both sides by P
2=1.071^time
take the ln of both sides
ln2=timeln1.071
divide both sides by ln 1.071
(ln2)/(ln1.071)=time needed
using calculator
10.1052=time needed
about 10.1 hours

Which method correctly solves the equation using the distributive property? Negative 0. 2 (x minus 4) = negative 1. 7 Negative 0

xenn [34]

The method which is used to solve the provided equation using the distributive property is,

$\rm x = 4 + 8.5 = 12.5$

<h3>What is distributive property?</h3>

The distributive property is to make something easier to do or understand and to make something less complicated.

The given expression is $\rm - 0.2(x-4) = -1.7$ .

The expression can be written as

$\rm 0.2(x-4) = 1.7$

Divide both sides by 0.2

$\rm x-4 = \dfrac{1.7}{0.2} = 8.5$

Add 4 both sides, we have

$\rm x = 4 + 8.5 = 12.5$

Thus, the value of x is 12.5.

More about the distributive property link is given below.

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.

kotegsom [21]

Answer: $(-9, 16]$

This is the interval from -9 to 16. Exclude -9 but include 16.

=====================================================

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

$-2 < x \le 3$

$5(-2) < 5x \le 5(3)$

$-10 < 5x \le 15$

$-10+1 < 5x+1 \le 15+1$

$-9 < 5x+1 \le 16$

This converts to the interval notation $(-9, 16]$

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
