Convert the equation to the standard form for a parabola by completing the square on x or y as appropriate.

RideAnS [48]

Y² + 2 y - 2x - 3 = 0
x + 3 = y² + 2 y
2 x + 3 = y² + 2 x + 1 - 1
2 x + 3 = ( y + 1 )² - 1
2 x + 3 + 1 = ( y + 1 )²
Answer:
2 ( x + 2 ) = ( y + 1 )²

64=(x+8)+90<br><br>what does x equal

Tomtit [17]

$Solution, solve\:for\:x,\:64=\left(x+8\right)+90\quad :\quad x=-34$

$Steps:$

$64=\left(x+8\right)+90$

$\mathrm{Switch\:sides}, \left(x+8\right)+90=64$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a, x+8+90=64$

$\mathrm{Add\:the\:numbers:}\:8+90=98, x+98=64$

$\mathrm{Subtract\:}98\mathrm{\:from\:both\:sides}, x+98-98=64-98$

$\mathrm{Simplify}, x=-34$

$\mathrm{The\:Correct\:Answer\:is\:x=-34}$

$\mathrm{Hope\:This\:Helps!!!}$

Answer:

$\bf C)\: -\cfrac{1}{32}$

Step-by-step explanation:

$\tt \cfrac{1}{2^{-2}x^{-3}y^5}$

$\tt x=2\\y=-4$

~

Substitute ''x'' with '2' & 'y' with "-4":-

$\tt \cfrac{1}{2^{-2}\times \:2^{-3}\left(-4\right)^5}$

First let's solve $\tt 2^{-2}\times \:\:2^{-3}\left(-4\right)^5$

$\tt 2^{-2}\times \:2^{-3}=\boxed{\cfrac{1}{32} }$

$\tt \cfrac{1}{32}\left(-4\right)^5$

Calculate exponents:- -4^5= -1024

$\tt \cfrac{1}{32}\left(-1024\right)$

Remove parentheses, apply rule:- $\tt a\left(-b\right)=-ab$

$\tt-\frac{1}{32}\times \:1024$

$\tt \cfrac{1}{32}\times \cfrac{1024}{1}$

Apply fraction rule:-

$\tt -\cfrac{1\times \:1024}{32\times \:1}$

$\tt \cfrac{1024}{32}$

Divide numbers:-

$\tt -32$

Now that we're done factoring the denominator let's bring down the numerator which is ' 1 ':-

$\tt -\cfrac{1}{32}\;\; \bf Answer$
