For example on -9+6 you would start at -9 and go right 6 times over and what you land on is your answer<span />
The 2 angles form a linear pair and angles that form a linear pair have a sum of 180 so
10x + 15 + 5x = 180
15 + 15x = 180
180 - 15 = 15x
165 = 15x
11 = x
The 400th term is 425.There are floor(√400) = 20 squares in the range 1..400, so the 400th term will be at least 420. There are floor(∛420) = 7 cubes in the range 1..400, so the 400th term may be as high as 427. However, there are
![\lfloor\sqrt[6]{427}\rfloor=2](https://tex.z-dn.net/?f=%5Clfloor%5Csqrt%5B6%5D%7B427%7D%5Crfloor%3D2)
numbers that are both squares and cubes. Consequently, the 400th term will be 427-2 =
425.
If a vertical line crosses the relation on the graph only once in all locations, the relation is <span>a </span>function. If<span> a vertical line crosses the relation more than once, the relation is </span>not a function<span>. So number 18 is not a function but number 19 is a function.
Hope this helps!!</span>
