HELP

Y = 1

X= -1

Step-by-step explanation:

Y is 3 so x is 2 and if y = x then x - 1 would be one and then that would make y = 1

X is 2 - y which is 3 will equal -1

Step-by-step explanation:

2x – 3y = -5(i)

у = х – 1(ii)

Multiply equation (ii) by 3,

3у = 3х – 3(iii)

Add (i) and (iii)

2x – 3y = -5

+

-3x + 3y = – 3

=

-x = -8

x = 8

put the value of x in eq (ii)

у = х – 1

у = 8 – 1

y = 7

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
