Option B is going to be your answer.

When you FOIL you get the following:

k(k) + k(- 1) - 2(k) - 2(-1)

Simplify and get:

k² - k - 2k + 2

Combine like terms for your final answer:

k² - 3k + 2

A 78 gram sample of Uranium loses half of its mass each year. What is the exponential equation? Please explain why A is the corr

Fiesta28 [93]

Answer:

Step-by-step explanation:

The first answer is correct because we have a decay factor.

The sample is losing mass, so the number that is being multiplied by a power of x must be less than 1.

If the second answer were used, then the sample would be gaining mass.

Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2

nlexa [21]

Answer:

Yes!

The solution to the equation is n = 2

Step-by-step explanation:

Given the equation

$4\left(n\right)-3=-2\left(n\right)+9$

remove the parentheses

$4n-3=-2n+9$

Add 3 to both sides

$4n-3+3=-2n+9+3$

Simplify

$4n=-2n+12$

Add 2n to both sides

$4n+2n=-2n+12+2n$

Simplify

$6n=12$

Divide both sides by 6

$\frac{6n}{6}=\frac{12}{6}$

Simplify

$n=2$

Therefore, the value of n = 2.

Hence,

Yes!

The solution to the equation is n = 2
