Nine years ago, Tarah opened a savings account with her bank. She started with a balance of $359 and has not made any withdrawal
Nikitich [7]

Answer: They should have like $100.52 Or something I’m assuming

Step-by-step explanation: I’m doing this to finish the 3 steps for this website and I have no idea what this is. So like she has $359, pays 8% interest for 9 years, 359 x 0.08 x 9 or however, someone else who’s a pro do this.

I have no idea what im doing

Answer:

  • x = - 6

Step-by-step explanation:

A hole is an input value that makes both numerator and denominator equal to zero.

<u>Let's factorize the numerator and denominator:</u>

  • 3x² - 108 = 3(x² - 36) = 3(x + 6)(x - 6)
  • x² + 2x - 24 = x² + 6x - 4x - 24 = x(x + 6) - 4(x + 6) = (x - 4)(x + 6)

<u>We have same factor of x + 6:</u>

  • x + 6 = 0
  • x = - 6 is a hole

Andy completes the square for the equation x2 + 6x - 8 = 0. Which of the following equations reveals the vertex of the parabola?
Stolb23 [73]
If the equation x^2+6x-8 has undergo completing the square, the answer would be:
x^2+6x-8&#10;
x^2+6x+9-8-9
**In this example, since 6x is the middle term, what comes to my mind is the polynomial (x+3) because 2ab results into 6x. [from the special products lesson (a+b)^2=a^2+2ab+b^2 ] 
(x+3)^2 -17 = 0
So if the equation is equal to y, then this equation's
y+17=(x+3)^2
The vertex would be on the point (-3, -17)

LET me know how you got the answer
andre [41]

6/2*3 / 3(3)

First simplify the numerator: 6/2*3 = 3*3 = 9

Next simplify the denominator: 3(3) = 3*3 = 9

So you have 9/9, which equals 1.


The 3rd answer is correct.
