First one who posts the correct answer wins. No cheating using calculators. ok here's the question: s+2=38 the square root of s. Now take the square root of s and divide it by 6. Take that number and add it to 4,167. Now subtract that number by 612. Now divide it by 50. Your answer? (remember when dividing there may be a remainder. if there is remember to put it there in your answer)

Determine whether each function is linear or quadratic. Identify the quadratic,linear, and constant terms.
1.y = x + 4
2. y = 2x2 - (3x - 5)
3. y = 3x(x - 2)
4.f(x) = x2 – 7
5.y = (x - 2)(x + 5)
6.g(x) = -7(x - 4)
7.h(x) = (3x)(2x) + 6
8. y = x(1 - x) - (1 - x2) 9. f(x) = -x(2x + 8)
