If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.
If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)
If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
Hey there! Your answer us -24° And here you would use subtraction. Hope this helped!! Your fellow Brainly user, GalaxyGamingKitty.
Answer:
The two integers you are finding is 21 and 23.
x² + y² = 970
970 / 2 = 485 ( divide it to two because we are finding two integers )
√ 485 = 22.022715546 or when rounded off, 22 ( square root because we are finding squares )
It means, the answers are near the number 22.
I found out 21 and 23
21 and 23 is two consecutive odd integers
Let x = 21
Let y = 23
x² + y² = 970
( 21 )² + ( 23 )² = 970
= 441 + 529
= 970

A is the answer
By AAS congruence theorem, ΔABD is congruent ΔCDB.
Quadrilateral ABCD is given in the figure.
<h3>What is the congruence theorem?</h3>
Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
Given, AB║DC
Consider ΔABD and ΔCDB
m∠A=m∠C=90° (Given)
m∠ABD=m∠BDC (Alternate interior angles)
BD = BD (Common)
Using AAS congruence theorem, ΔABD ≅ ΔCDB
Hence, by AAS congruence theorem, ΔABD is congruent ΔCDB.
