Answer:

x= -3, y=12

x=1/2, y=8 1/2

Step-by-step explanation:

y = 9-x

y= 2x²+4x+6

  • 9-x= 2x²+4x+6
  • 2x²+5x-3=0

solving, we get

  • x= -3 and x= 1/2

then

  • for x= -3, y= 9+3= 12
  • for x=1/2, y= 9-1/2= 8 1/2

<span>  x^2 +(x-4)^2 =20^2</span>

<span>  x^2 +(x-4)^2 =400</span>

x^2 +(x-4)^2 -400=0

factor:

2x^2-8x-384=0

Factor the 2 out of 2X^2

2(x-16) (x+12) =0

<span> Divide both sides by 2</span>

(x-16) (x+12) =0

X=16 , x=-12

<span> Number cannot be negative so x=16</span>

If several points are graphed on a number line, is the point that is the farthest from 0 always the greatest?explain.
balandron [24]

Answer:

No

Step-by-step explanation:

On a number line, the 0 is in the middle. Positive numbers are to the right of the 0 and negative numbers are to the left of the 0. A point farthest from 0 could be on the left side and therefore be really small. Therefore the point farthest from 0 is not always the greatest as it could also be the smallest

Ann [662]

Answer:

The answer is "Option C"

Step-by-step explanation:

The using formula= (1+\frac{r}{n})^n -1

→r = rate

→ n = compounded value

In choice a:

When compounded is monthly 4.0784\%  

n = 12

\to (1+ \frac{0.040784}{12})^{12} = 1.0403-1 = 0.0403

In choice b:

When compounded is quarterly4.0792\%

n = 3\\\\\to (1+ \frac{0.040792}{12} )^{3} = 1.0102-1 = .0102

In choice c:

Whenn compounded is daily 4.0730 \%

n = 365\\\\\to (1+ \frac{0.040730}{12})^{365}  = 3.328-1 = 2.328

In choice d:

When compounded is semiannually4.0798\%

n = 2\\\\\to (1+ \frac{0.040798}{12})^{2} = 1.0066-1 = 0.0066
