Answer:
120 student and 80 adult tickets
Step-by-step explanation:
8x + 10y = 1760
x + y = 200
The rational zero theorem looks at the number of sign changes in the equation's terms when x is evaluated with a positive or negative number. In your problem, if we insert a positive value for x:
1st term stays +, 2nd term stays -, 3rd term stays -, last term stays +.
Read from left to right and determine the number of sign changes:
+ - - + [there is a change from + to -, no change from - to -, and a change from - to +] Therefore 2 sign changes. There can be two positive rational zeros, or zero rational zeros [It's always the number of sign changes, and then every other number less than the number of sign changes, and zero]
Let's now do it for a negative x:
1st term becomes -, 2nd term stays -, 3rd term becomes +, last term stays +
- - + + [there is no sign change from - to -, one change from - to +, no change from + to +] Therefore one sign change. There can be one negative rational zero, or zero rational zeros.

The two quadrilateral with the listed properties are kite and rhombus respectively.
<h3>Properties of a kite</h3>
- It has two diagonals intersecting at right angles
- A kite is symmetrical about its main diagonal
- Angles opposite to the main diagonal are equal
- The kite can be viewed as a pair of congruent triangles with a common base
- Its diagonals are perpendicular
<h3>Properties of a rhombus</h3>
- All sides of the rhombus are equal
- The opposite sides are parallel
- Opposite angles are equal
- Diagonals bisect each other at right angles
- Diagonals bisect the angles
- The sum of two adjacent angles is equal to 180 degrees, that is, are supplementary
Thus, the two quadrilateral with the listed properties are kite and rhombus respectively.
