How many solutions can be found for the equation 5x + 3(x − 1) = 10x − 2x − 3?

Lady_Fox [76]

Infinitely many solutions. Since your slope and Y axis values are the same on both sides no matter what you fill in for x your answer will be true.

Given g(x) = x square -7x + 1over4 show that the least possible value of g(x) is -12

aliina [53]

Answer:

$-\frac{45}{16}$

Step-by-step explanation:

$g(x)=\frac{x^{2} -7x+1}{4}$

Take the derivate of g:

$g'(x)=\frac{x-7}{4}$

Find x that:

g'(x)=0

<h2>solving:</h2>

$\frac{2x-7}{4}=0\\x=\frac{7}{2}$

This x give the least possible value that are g(7/2):

$g(\frac{7}{2}) =-\frac{45}{16}$

Answer:

$\frac{1}{2} x^{\frac{5}{4} }y^{\frac{10}{3}}$

Step-by-step explanation:

$\frac{x^{\frac{5}{2} }*6y^2*\sqrt[3]{y^4} }{12x^{\frac{1}{2}}*\sqrt[4]{x^3} } =$
$\frac{x^{ \frac{5}{2} }6y^2y^{ \frac{4}{3} } }{12x^{ \frac{1}{2} }x^{ \frac{3}{4} }} =$
$\frac{1}{2} x^{\frac{5}{2} - \frac{1}{2} - \frac{3}{4}}y^{2+\frac{4}{3}}=$
$\frac{1}{2} x^{\frac{5}{4} }y^{\frac{10}{3}}$
