Find the roots of the quadratic equation x^2-8x=9 by completing the square. Show your work.
qaws [65]
x^{2} -8x=9 \\  x^{2} -8x+(-4)^{2} = 9 + (-4)^{2}  \\  x^{2} -8x+16 = 9 + 16 \\  (x-4)^{2} =25 \\ x-4= \sqrt{25}  \\ x-4= \pm 5 \\ x= \pm 5+4

The slope of y = 3x is 3, and the slope of y = -3x is well, yes, you guessed it, is -3, same value, just different sign, and when that happens the slopes are just mirroring each other, in this case, the mirror line, line of symmetry, is the y-axis, notice in the picture below.

Find the remainder when 1!+2!+3!+...+15! is divided by 15
Anettt [7]

Answer:

  • 3

Step-by-step explanation:

<u>We know that </u>

  • n! = 1*2*3*...*n

<u>We also know that </u>

  • 15 = 3*5

<u>Since 5! = 1*2*3*4*5 is divisible by 15:</u>

  • any n! with n ≥ 5 is divisible by 15.

We need to find the remainder when 1! + 2! + 3! + 4! is divided by 15 as all the rest are divisible by 15.

<u>The sum is:</u>

  • 1! + 2! + 3! + 4! = 1 + 2 + 6 + 24 = 33

<u>The remainder is:</u>

  • 33/15 = 2 rem 3

As we see the remainder is 3
