<1 and <2 are supplementary angles. m <1 is 4y+7, and m<2 is 9y+4. Find m<2.
Yuliya22 [10]

Okay, so supplementary angles = 180 degrees.

Starting equation : 4y + 7 + 9y + 4 = 180

Combine like terms : 13y + 11 = 180

Subtract 11 from both sides : 13y = 169

Divide 13 from both sides : y = 13

Insert y value into original m<2 equation : 9(13) + 4

Solve : 121 degrees


If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.

4(13) + 7 = 59

59 + 121 = 180

The limit as x-approaches 3 of f(x) is x-3 over x squared -9
Luden [163]

notice that the denominator can be factored into (x-3)(x+3).

Now you can cross out (x - 3) from the numerator and denomiantor resulting in a simplified fraction of \frac{1}{x+3}

Plug the limit value (which is 3) into the simplified fraction.

Answer: \frac{1}{6}
