Answer:

Step-by-step explanation:

She earns $3,567 and spends $2,895. That means that $2,895 is taken away from how much she earns each month. Subtraction is the correct operation, cancelling out choices B and D

$3,567 - $2,895

Now, you need to figure out the answer to the above problem. Choice C is your answer.

What is the explicit formula for arithmetic sequence {-20, -5, 10, ...}? Use f(n) where is 1, 2, 3, and so on.

vekshin1

Answer: B

Work:
Since the general formula of an arithmetic sequence is f(n) = (the first term) + (common difference)*(n-1), you just plug in what was given to you in the problem to that equation. The first term is -20 and the common difference is +15 since the the increase from one term to the next is 15. Doing so produces the equation f(n) = -20 + 15(n-1), which is choice B.

I REALLY NEED HELP ON THIS QUESTION!

Answer: The correct answer is: [A]: " x = - 1/2 " .

_______________________

Step-by-step explanation:

_______________________

Given:

4x − 6 = 10x − 3 ; Solve for "x" ;

Let us add "3" to each side of the equation;

and subtract "4x" from each side of the equation:

______________________

4x − 6 + 3 − 4x = 10x − 3 + 3 − 4x ;

______________________

to get:

______________________

-3 = 6x ;

______________________

↔ 6x = -3 ;

______________________

Now, divide Each Side of the equation by "6" ;

to isolate "x" on one side of the equation;

and to solve for "x" ;

______________________

6x / 6 = - 3 / 6 ;

to get:

x = - 3/ 6 ;

$= -\frac{3}{6} = -\frac{(3/3)}{(6/6)}=-\frac{1}{2}$ .

______________________

→ which is: Answer choice: [A]: " $x = -1/2$ " .

______________________

Hope this helps!

Wishing you well in your academic endeavors!
