Answer:
x = 1
Step-by-step explanation:
Note that the x-coordinates of the two given points are identical. This tells us immediately that the line is a vertical one whose slope is undefined.
The equation of this line is x = 1.

Answer:
-45
Step-by-step explanation:
The question is asking for the sum of the sequence. Therefore, there is no such thing as a "radians" answer.
When you evaluate the sum, you should get -45 as your answer. To find so, you simply plug in 1 as <em>n</em> and other numbers then add the result.
Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.
X=6
Step-by-step explanation:
(8x-4)+(3x+17)=(17x-23)
Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.
11x+13=17x-23
Now this is what the equation should look like after combining ur alike terms.
11x+13=17x-23
-11x. -11x.
now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.
13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.
36=6x and now u just divide the 36 by 6 and remember to always divide by the x
Now the answer is x=6
Answer:
20/3
Step-by-step explanation:
8 times 3 plus 2 is 20. So 20/3
