The legs of a right triangle are the sides that are connected to the 90 degree (right) angle. The remaining side is called the hypotenuse.

Another way to look at it is the two legs of a right triangle are the two shorter sides. The longest side is the hypotenuse.

Answer:

1) When x is 1, y is 4, and vice versa

2) When x is -6, y is 42, and when x is 7, y is 114

3) When x is -2, y is 2, and when x is 8, y is 42

Step-by-step explanation:

1)

$y=x^2-6x+9$

$y+x=5$ which can be rearranged as $y=5-x$ .

Substituting this lone y into the first equation, you get:

$5-x=x^2-6x+9$

Move everything to one side:

$x^2-5x+4=0$

Factor:

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

$x=1, 4$

$y=4, 1$

2)

$y-30=12x$ which can be rearranged as $y=12x+30$ .

$y=x^2+11x-12$

Let's use elimination this time and subtract the first equation from the second:

$0=x^2-x-42$

Factor:

$(x-7)(x+6)=0$

$x=-6, 7$

$y= -42, 114$

3)

$y=x^2-2x+6$

$y=4x+10$

Let's set the two equations equal to each other through substitution:

$x^2-2x-6=4x+10$

Move everything to one side:

$x^2-6x-16=0$

Factor:

$(x-8)(x+2)=0$

$x=-2, 8$

$y= 2, 42$

Hope this helps!

Answer:

297 miles

Step-by-step explanation:

The round-trip distance from X to Y is double the one-way distance. The distance from X to Y is 648/2 = 324 miles.

That distance is the sum of distances from X to Z and Z to Y. Then ...

XZ +ZY = XY

27 +ZY = 324

ZY = 297

It is 297 miles from City Z to City Y.

Answer:

D. 0.343

Step-by-step explanation:

You can see the first three options as 0.340 so if you substract this number with 0.343 the remainder is positive 3.

This strategy also can be applied to the number 0.3409 but in this occasion the result is different:

$0.343 - 0.3409 = 2.1\times 10^{-3}$

That is small number but still is positive that's meaning that between 0.343 and 0.3409 the greatest value is 0.343 .
