REALLY APPRECIATE YOUR HELP<br><br>Given log x = 3 and log y = 2, prove that x^2 -7xy =3000y​​
anyanavicka [17]

Answer:

if \:  log(x )  = 3 \\  log_{10}(x)  = 3 \\   {10}^{3}  = x \\ therfore \to \:  \boxed{x =  {10}^{3} } \\ \\  if \:  log(y )  = 2 \\  log_{10}(y)  = 2 \\   {10}^{2}  = y \\ therfore \to \:  \boxed{y=  {10}^{2} }

Step-by-step explanation:

x^2 -7xy =3000y \: then \to \\ x^2 =3000y + 7xy \\ {(10 ^{3} )}^{2}  = 3000(10)^{2}    + 7( {10}^{3} \times  {10}^{2})  \\   {10}^{6}   = 3000(10)^{2}    + 7( {10}^{3} \times  {10}^{2})  \\   {10}^{6}   = 3000(10)^{2}    + 7( {10}^{5} )   \\  {10}^{6}  = 300000 + 700000 \\   \boxed{{10}^{6}  = 1000000} \\ hence \: the \: equation \to \: x^2 -7xy =3000y \\ \boxed{ is \: corret}

Add the like terms: -3ab+-10a+-8a
Stolb23 [73]
-10a and -8a are like terms, but -3ab is not equivalent.  With the two a terms, we have:

-10a-8a

a(-10-8)

-18a

We then add in the other term (-3ab) for a final result of -3ab+-18a.  This can be factored alternatively as -3a(b+6).

A company did a quality check on all the packs of trail mix it manufactured. each pack of trail mix is targeted to weigh 9.25 oz
MariettaO [177]

Rejected masses x are those that weigh less than 9.02 oz or more than 9.48 oz.

<h3>What is the range?</h3>
  • In mathematics, the range of a function can refer to one of two notions that are closely related.
  • The function's codomain, the function's visual representation.
  • A binary relation f between two sets X and Y is a function if for every x in X there is exactly one y in Y such that f relates x to y.

To find the rejected masses:

  • If each pack of trail mixes is supposed to weigh 9.25 oz and must be within 0.23 oz of that weight to be accepted, then rejected masses x are those that weigh less than 9.02 oz or more than 9.48 oz.

Therefore, rejected masses x are those that weigh less than 9.02 oz or more than 9.48 oz.
