Simple...

y= $x^{2} -9$

$y= x^{2} -9$

It's quite easy to see $x^{2} = x^{2}$

Thus, any value of x makes the equation true.

Thus, your answer.

The walking distance that is saved by cutting across the lot is

dezoksy [38]

Using the Pythagorean Theorem, we have x^2+(x+2)^2=51^2, and
x^2+ x^2+4x+4=2x^2+4x+4=51^2. After that, we subtract 51^2 from both sides to get 2x^2+4x-2597. Using the quadratic formula (x=(-b+-sqrt(b^2-4ac))/2a in ax^2+bx+c), we get around 35 for x. We did + instead of minus after b due to that it can't be negative! x+2=37, so you save 35+37-51=around 21 feet

What is the slope that passes through the lines (2.1,-4.2) and (2.5,-5)

Usimov [2.4K]

slope = (y2-y1)/(x2-x1)

= (-5--4.2) /(2.5 -2.1)

(-5+4.2)/(2.5-2.1)

=-.8/.4

m=-2

the slope is -2
