The formula for finding the circumference of a circle is c=2πrc=2πr . rearrange the formula to solve for the radius (r).

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Solve the following inequalities and show the solution on a number line. 2x+3< 3(4x+5)
