Answer:

The first 2 on top is not a function. The 3rd one on top and the bottom 2 are functions.

Step-by-step explanation:

The x-value cannot have more than 1 y-value or else when you plot the points on the graph, it doesn't meet the vertical line test. The vertical line test indicates whether or not the graph is a function. Different x-values can have the same y-value.

Function examples: (3,-4), (5,0), (0,-4), (1,2)

Not a Function examples: (0,8), (2,-1), (0,-2), (-5,3)

Please refer to the following attachment and find the value of x.
Drupady [299]

Answer:

5

Step-by-step explanation:

Sum of interior angles in a 4 sided quadrilateral is 360,

110 + 70 + 14x + 23x - 5 = 360

180 + 37x - 5 = 360

180 - 5 + 37x = 360

175 + 37x = 360

37x = 360 - 175

37x = 185

x = 185 / 37

x = 5

A parallelogram is shown below:
lana66690 [7]

Answer:

a). Area of the parallelogram = 8 cm²

b). Area of both the triangles = 4 cm²

Step-by-step explanation:

a). Area of the given parallelogram ABCD = Base × Height

                                                                 = DC × (Vertical distance between

                                                                              AB and DC)

                                                                 = 9 × \frac{8}{9}

                                                                 = 8 ft²

b). If we decompose this parallelogram into two triangles ΔABC and ADC by a diagonal AC,

Area of both the triangles will be equal.

(Since, diagonal of a parallelogram divides the parallelogram into two equal triangles)

Therefore, area of ΔABC = Area of ΔADC = 4 ft²
