In scientific notation, a number may be expressed as N x 10"
true or false?

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

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.

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with
