Eman walks from the store to her friends house, 2 miles away. It takes her 35 minutes.

Write the fraction that represents her constant speed, C, if she walks y miles in 10 minutes

y = a (x - h) 2 + k, where (h, k) is the vertex. in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down.
