The answer is C, t-19=-12. This is because the temperature decreased from t by 19 degrees and ended up at -12 degrees. Hope this helped!
Y=(-5/7)x+5
Subtract 5x over to the right side to isolate y. then divide everything by 7. Hope this helps
The sum of all interior angles in a polygon is
180(n-2), where n = sides, well, this is a QUADrilateral, so it has 4 sides, so the total is 360°.
now, let's find what angle C is first,

now, recall the "inscribed quadrilateral conjecture", where opposite angles are "supplementary angles", thus
Answer:
A parallelogram is a quadrilateral with both pairs of opposite sides parallel. And this picture you just showed me right now thats why those are all parallelograms.

Answer:

Step-by-step explanation:
The slope of a line is the same everywhere, so an equation can be written making use of that fact.

Cross-multiplying gives ...
2(y -5) = x -2
2y -10 = x -2 . . . eliminate parentheses
2y = x +8 . . . . . . . add 10; next, divide by 2

These equations match choices B and D.
