Answer:

The value of X in the equation 3X (-1) / 9Y equals 18 when Y equal 27 is 1458.33

Step-by-step explanation:

$\frac{3X - 1}{9 Y} = 18$ is a polinomial equation A

if the value of Y = 27

put this value of Y in the equation A

$\frac{3 X -1}{9 \times 27} = 18$

$\frac{3 X -1}{243} = 18$

243 will be taken to right hand side and as per rule will be multiplied by 18

$3X-1= 18\times 243\\$

$3X-1= 4374$

1 will be taken to right hand side and added as per rule

$3 X = 4374+1\\3X= 4375$

3 wil be taken on right hand side and divided as per rule

$X= \frac{4375}{3} \\X= 1458.33$

So the value of X if Y = 27 is 1458.33

Find the zeros of the polynomial x^2 + 8x + 16

Scorpion4ik [409]

hey mate,

$x^2 + 8x + 16 = 0$

<=>

$(x+4)^2 = 0$

As we know that $(a+b)^2 = a^2+b^2+2ab$

then

$(x+4)^2 = 0$

<=> (x+4) = 0

<=> x = -4

so there is one solution x = -4

thanks

Which of the following equations best describes a square root function that is reflected across the x-axis and has a vertex of (

Minchanka [31]

Answer:

Step-by-step explanation:

Rather than picking, let's try to construct one from the description.

reflected over the x axis means - $\sqrt{x}$

the vertex is usually at (0,0), now how do we move a graph? or in other words translating it.

To move left and right you use $\sqrt{x-h}$ where if you subtract h you move right and if you add h you move left. we go from (0,0) to (-4,2). so 0 to -4 is 4 left, so that means we add 4.

To move up and down we use $\sqrt{x}+v$ Here if v is positive you move up and if v is negative you move down. going from (0,0) to (-4,2) it moves up 2
