Partition the set A into 4 subsets: {1, 8}, {2, 7}, {3, 6}, and {4, 5}, each consisting of two integers whose sum is 9. If 5 integers are selected from A, then by the Pigeonhole Principle at least two must be from the same subset. But then the sum of these two integers is 9.

vaieri [72.5K]

Step-by-step explanation:

This can be modeled by the equation f(x)=7+5x

Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22

If x=50 then f(50)=7+5(50)

f(50)=$257

What is equation for the line that is perpendicular to y-3=-4(x+2) and passes through the point (-5,7)
jekas [21]

Answer:

y-7=1/4(x+5)

Step-by-step explanation:

y-3=-4(x+2)

y=-4x-8+3

y=-4x-5

-----------

y-y1=m(x-x1)

y-7=m(x-(-5))

y-7=m(x+5)

perpendicular means negative reciprocal of the slope,

so the slope will be 1/4

y-7=1/4(x+5)
