Solve by factoring...<br><br> 1) y=6x^2-13x-5<br><br> 2) y=4x^2-7x+3

Amanda [17]

Answer:

1) $x=-\frac{1}{3}, x=\frac{5}{2}$

2) $x=1, x=\frac{3}{4}$

Step-by-step explanation:

1)

Given

$f(y)= 6x^{2} -13x-5=0$

Equating above equation.

$6x^{2} +2x-15-5=0$

$2x(3x+1)-5(3x+1)=0$

$(3x+1)(2x-5)=0$

Solving for both the equation

$3x+1=0$

$3x=-1$

$x=-\frac{1}{3}$

$2x-5=0$

$2x=5$

$x=\frac{5}{2}$

$x=-\frac{1}{3} ,x=\frac{5}{2}$

2)

Given

$f(y)=4x^{2} -7x+3=0$

$4x^{2} -4x-3x+3=0$

$4x(x-1)-3(x-1)=0$

$(x-1)(4x-3)=0$

Solving for both equation

$x-1=0$

$x=1$

$4x-3=0$

$4x=3$

$x=\frac{3}{4}$

$x=1, x=\frac{3}{4}$

Find the minimum value of <br> C=x+3y

Marysya12 [62]

Answer:

DNE

Step-by-step explanation:

If x and y may be any real number, there is no minimum value for C. It can approach negative infinity.

If C is a constant, and the domain of x is all real numbers, there is no minimum for y. It can approach negative infinity.

We're not sure what you want or what restrictions may exist. The given relation does not suggest any minimum. We'd have to say it Does Not Exist
