<em>Greetings from Brasil...</em>

Let's solve this inequality.

Let's isolate X. For this, the elements that are with it must be sent to both sides:

- 3 < - 4X + 1 < 13

- 3 - 1 < - 4X < 13 - 1

- 4 < - 4X < 12

<h2>- 3 < X < 1</h2>

<em>important: see annex</em>

Cerebral $500 for four years at 3% interest compounded annually use the formula to calculate the total amount she will have to p
Black_prince [1.1K]
Since we're doing compound interest for four years it will be simpler than daily.
In case you didn't know the formula, here it is: A = P (1 +r/n)^(nt)
now lets substitute.
A = 500 (1 + 0.03)^4
A = 500 (1.03)^4
A = 500 (1.12550881)
A = 562.754405
Since that decimal is too big for cash, let's round it. Notice that the number after 5 is lower than 5. Thus the first two numbers stay the same and the final answer will be..
A = 562.75
Hope this helps :3

Answer:

  6x^2 +x -12

Step-by-step explanation:

Substitute for A and B and collect terms.

  2B +3A

  = 2(3x^2 -x +3) +3(x -6) . . . . substitute for A and B

  = 6x^2 -2x +6 +3x -18 . . . . . eliminate parentheses

  = 6x^2 +x -12 . . . . . . . . . . . . collect terms
