The heights in cm of some pupils are:149, 111, 171, 166, 152, 129, 162, 144. work out the mean heights of the pupils

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Someone this asap for a group of students attends a basketball game. * the group buys x hot dogs at the concession stand for $2 each. * the group buys y drinks at the concession stand for $3 each. the group buys 29 items at the concession stand for a total of $70. how many hot dogs did the group buy?

50 plz, given the system of equations, match the following items. x + 3 y = 5 x - 3 y = -1 a) x-determinant b) y-determinant c) system determinant match the following to the pictures below.
