The solution of a+b>12 is a>−3. What is the value of b?

Plz HELP ME I REALLY NEED THIS

Simone claims the initial value and y-intercept are the same thing on a graph. is she correct? if you know that a line has a slope of and a y-intercept of 7, what is the equation for that line in slope-intercept form?

X2 + y 2 = 36 x + y = 6 solve the system of equations.

Solve the following inequalities and show the solution on a number line. 3/4 (2x-7) ≤ 5
