What is the vertex of the parabola? y+1=−14(x−2)2 enter your answer in the boxes?

The box plots show the distributions of the numbers of words per line in an essay printed in two different fonts.which measure of center would be best to compare the data sets? the median is the best measure because both distributions are left-skewed.the mean is the best measure because both distributions are left-skewed.the median is the best measure because both distributions are symmetric.the mean is the best measure because both distributions are symmetric

X+ 4y − z = −14 5x + 6y + 3z = 4 −2x + 7y + 2z = −17

What is not a question to ask to determine the reasonability of a solution
