Flashback 9-26-12When graphed in the (x,y) coordinate plane, at what point do the linesx+y= 5 and y= 7 intersect?A.(2,0)B.(2,7)C.(0,7)D.(2,5)E.(5,7)Joke of the dayWhat did the square say to the circle?
Youre pointless!
Square/Cube Roots and the Pythagorean Theorem
The square root of a positive number a, written , is the number we square to get a. If = b, then .
Simplify:
Pythagorean Theorem:a + b = c(c = hypotenuse, b and a = legs)
If c is the hypotenuse of a Right Triangle, and a and b are legs, find the missing side of the Right Triangle:a = 12, b = 16, find c.25 = c, b = 24, find a.17 = c, a = 8, find b.Simplifying Square Roots (Radicals)Factor out the perfect square factors that are under the square root sign.
