The slope is undefined, because the x values are the same.
Answer:
x = 22
Step-by-step explanation:
same- side exterior angles are supplementary, thus
4x + 15 + 3x + 11 = 180, that is
7x + 26 = 180 ( subtract 26 from both sides )
7x = 154 ( divide both sides by 7 )
x = 22

Hope I helped, also, I used the math thingy, which I haven't used before, so I'm not sure quite how this turned out, well, I guess we will see in a minute! But if it does not work I can try it just typing regularly.
Answer:
Domain : {-9, 2,4,5}
Range: { -3,1,3,9}
Step-by-step explanation:
The domain is the input values
The domain is the x values in the pairs
Domain : {2,4,5,-9}
We usually put them in numerical order
Domain : {-9, 2,4,5}
The range is the output values
The range is the y values in the pairs
Range : { 3,1,-3,9}
We usually put them in numerical order
Range: { -3,1,3,9}
