Prove that for each natural number n > 43, we can write
n = 6xn + 9yn + 20zn

for some nonnegative integers xn, yn, zn. then prove that 43 cannot be written in this
form.
(hint: write 44, 45, 46, 47, 48, and 49 in the given form. use induction to prove
that any larger number can be written in the given form.)

When are two distinct non vertical lines parallel

The annual snowfall in a town has a mean of 38 inches and a standard deviation of 10 inches. last year there were 63 inches of snow. find the number of standard deviations from the mean that is, rounded to two decimal places. 0.44 standard deviations below the mean 2.50 standard deviations below the mean 0.44 standard deviations above the mean 2.50 standard deviations above the mean

Put the equation in slope intercept form by solving for y
