two right triangles are graphed on a coordinate plane. one triangle has a vertical side of 3 and a horizontal side of 7. the other triangle has a vertical side of 9 and a horizontal side of 21.
could the hypotenuses of these two triangles lie along the same line?
yes, because they are both right triangles
yes, because they are similar triangles
no, because they are not similar triangles
no, because one is larger than the other

What is the total area of the figure?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

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
