Answer:

j = 5

Step-by-step explanation:

-3 would have to be -3/1 or 3/-1

y1-y2 -3-6

____ _____

x1-x2 -2

-9/-2 we need -9/3 to get to -3 so if we substitute =the blank for 5, -2 +5 is 3 and we get the answer

sry if this is confusing im not the best as explaining

Which of the following expressions is modeled on the number line?

Anton [14]

Answer is D. last one

How to turn this equation: <br> y= -1.02(x-3)^2+9.25<br> 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:

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