Classify the equation 64x-16 = 16(4x-1) as having one solution, no solution, or infinitely many solutions.

USPshnik [31]

Take the equation and distribute the 16 on the right:

64x - 16 = 16(4x - 1)

64x - 16 = 64x - 16

Since what is on both sides is identical, you'll always get a true statement no matter what value you pick for x.

This equation has infinitely many solutions.

How to turn this equation: y= -1.02(x-3)^2+9.25 into factored form

MatroZZZ [7]

Answer:

$y=(102x-306-5\sqrt{3774})(102x-306+5\sqrt{3774})$

Step-by-step explanation:

You first equate it to zero to get:

$-1.02(x-3)^2+9.25=0$

Then solve using square root method

$-1.02(x-3)^2=-9.25$

$(x-3)^2=\frac{-9.25}{-1.02}$

$(x-3)^2=\frac{925}{102}$

$x=3\pm\sqrt{\frac{925}{102}}$

$x=3\pm{\frac{5\sqrt{3774}}{102}}$

$x={\frac{306\pm5\sqrt{3774}}{102}}$

Now work it backwards

$102x-(306\pm5\sqrt{3774})=0$

$(102x-306-5\sqrt{3774})(102x-306+5\sqrt{3774})=0$

Hence the factored form is:

$y=(102x-306-5\sqrt{3774})(102x-306+5\sqrt{3774})$

I need sambady help my to rate the question

OLEGan [10]

Counting by tens is faster than counting by ones because you skip more numbers in between 10 and the next number than just counting by ones
