Answer:

40 degrees

Step-by-step explanation:

The 100 degree angle is supplementary to angle CED. This means CED will end up being 80 degrees. Since the angles in all triangles equate to 180 degrees 80 + 60 + angle D must equal 180 degrees. Therefore, angle D has to be 40 degrees.

Fill in the table using this function rule. y=28 - 3x X Y 1 3 4 6

My name is Ann [436]

Answer:

So, you just end up plugging in your numbers.

y = 28 - 3(1)

y = 28-3

y = 25

Y = 28 - 3(3)

y = 28 - 9

y = 19

y = 28 - 3x

y = 28 - 3(4)

y = 28 - 12

y = 16

y = 28 - 3x

y = 28 - 3(6)

y = 28 - 18

y = 10
