Solve the following systems analytically. (Do not use any of the matrix techniques) a. 2 − 4 = −6
3 − 5 = −7

b. −4 = −2 − 10
2 = 2 + y

If the measure of xyz is 81 what is the measure of yz

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Which graph represents the function g(x) = |x + 4| + 2?
