XY = 17. 

Because YW is a perpendicular bisector, we can say that TW and WZ are both equal to 3. It tells us that XZ is 12, so that means that XW must be 12+3 which equals 15.

It also tells us that YW is 8. So we can use the Pythagorean Theorem to find the hypotenuse of Triangle XWY. Thus, 15^{2}  +  8^{2} =  XY^{2}

To solve this equation, square and add both of the terms on the right like this:
289 =  XY^{2}

And then take the square root of both sides. Your final answer should be: 
XY = 17.

6.The expressions 5 + 2(x –7) and 5 +2x –14are equivalent by the
satela [25.4K]

Answer:

6) Option B) distributive property  is correct

Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property

7) Option B) distributive property  is correct

Therefore  x+3(7-x)=x+21-3x are equivalent by using distributive property

Step-by-step explanation:

6) Given that the expressions 5+2(x-7) and 5+2x-14 are equivalent

To verify that the given expressions are equivalent by which property :

5+2(x-7)

=5+2(x)+2(-7) ( by using the distributive property a(x+y)=ax+ay )

=5+2x-14

Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property

Therefore option B) distributive property  is correct

7) Given that the expressions x+3(7-x) and x+21-3x are equivalent

To verify that the given expressions are equivalent by which property :

x+3(7-x)

=x+3(7)+3(-x) ( by using the distributive property a(x+y)=ax+ay )

=x+21-3x

Therefore  x+3(7-x)=x+21-3x are equivalent by using distributive property

Therefore option B) distributive property  is correct

PLEASE HELP!!
Alja [10]

Answer:

B choice

Step-by-step explanation:

y = mx + b

where m = slope and b = y-intercept.

The value of m is 3/4. That means slope is 3/4. Changing 3/4 to - 3/4 will make the slope become negative. Therefore the answer is B.
