Is a natural number always a rational number?

Find the vertex of the function given below y=x^2-6x+1

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
