Prove: x = 7

Answers

Answer 1
Answer:

Answer:

Easy

Step-by-step explanation:

-19-9=-28

-28/-4=7

thus x=7
Answer 2
Answer:

Final answer:

In solving the equation 9 - 4x = -19, we find that x = 7 is indeed the correct solution.

Explanation:

The given equation is 9 - 4x = -19. We are to solve this equation for x, and see if it equals 7, as stated in the question. Start by subtracting 9 from both sides, resulting in: -4x = -28. Next, divide both sides by -4 to solve for x, resulting in x = 7. So, indeed, for the given equation, x = 7 is the correct solution.

5x + y = 2
4x + y = 4

  5x + y = 2
-(4x + y = 4)

  5x + y = 2
-4x  - y  = -4
    x        = -2

x = -2 

5x + y = 2
5(-2) + y = 2
-10 + y = 2
y = 2 + 10
y = 12

x = - 2
4x + y = 4
4(-2) + y = 4
-8 + y = 4
y = 4 + 8
y = 12

x = -2 ; y = 12 ⇒ (-2,12)

Dylan’s essential (fixed) expenses are $900 per month, his essential (flexible) expenses are $400 per month, and his non-essential expenses are $295 per month. His 401-K retirement account has $12,000, and his emergency fund savings account has $3500. Dylan wants an emergency fund of 3 times monthly living expenses. How much more does Dylan need to save to have an adequate emergency fund?a. $1,450
b. $5,200
c. $1,285
d. $8,500

Answers

The Following "Verified" Answer is wrong. On Financial Math the answer is...

C.

$1,285

Answer:

Option C. $1,285 more Dylan need to save.

Step-by-step explanation:

Dylan's essential (fixed) expenses = $900 per month

His essential (flexible) expenses = $400 per month

His non-essential expenses = $295 per month

Total expenses per month = 900 + 400 + 295 = $1595.00

He wants an emergency fund of 3 times monthly living expenses

= $1595 × 3 = $4,785.00

currently, in Dylan's emergency fund account = $3,500

Dylan need to save more = 4,785 - 3,500 = $1,285.00

Dylan need to save $1,285 more to have an adequate emergency fund.
