Answer:

He is wrong

Step-by-step explanation:

for it to not be a function the x coordinates would have to repeat at some point

ex if it was not a solution:

(1,5)(1,8) (3,7) (5,9) (7,11)

as you can see the 1 repeats which makes it not a function but because your doesn't have anything repeating then its a function

Which expression is equivalent to 36/(4 + y)?
I am Lyosha [343]

Answer:

B) 36/(y+4)

Step-by-step explanation:

Use the process of elimination.

A cannot work because we are changing the operation. Instead of dividing thirty-six by the sum of four and a number, we are dividing thirty-six by four, then adding the unknown number. This is not the same as the original expression, so we know it is not this.

Next, check C. C doesn't seem right either. Remember that, unlike multiplication and addition, you cannot flip the order in which the operation is being done and still get the same answer. C says four plus a number divided by thirty-six, which is entirely different from our original expression. So the answer is not C.

And finally, check D. D doesn't work either. With D, we are dividing thirty-six by a number, then adding it to thirty-six divided by four. This is not the same as our original expression, so D isn't it.

That leaves us with B. Does it work? Yes, because changing the y and the four still will give the same thing. And yes, because 36 is being divided by the sum of that number and four. So it is our answer.

Answer:

The answer to your question is below

Step-by-step explanation:

I numbered the squares, see the picture below

Angle 3 and the angle given are vertical angles so they measure the same

             angle 3 = 137°

The sum of the angles 1, 2, 3 and 137 equals 360°, so

  angle 1 + 137 + angle 3 + 137 = 360

   and angle 1 and 3 are vertical angles so angle 1 = angle 3

   2angle 1 = 360 - 137 -137

    2 angle 1 = 86

        angle 1 = 86 /2

        angle 1 = 43°

        angle 2 = 43°

The angle given and the angle 5 are corresponding angles, they measure the same

        angle 5 = 137°

Angle 5 and 6 are vertical angles, they measure the same

        angle 6 = 137°

Angle 2 and angle 7 are corresponding angles, they measure the same

        angle 7 = 43°

Angle 3 and angle 6 are corresponding angles

         angle 6 = 137°

Angle 4 and 7 are vertical angle, so they measure the same

         angle 4 = 43°
