I need help here is the question 2/3 + 2 1/4

What is the value of x? enter your answer in the box. photo attached.

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

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.
