2. There are four natural numbers whose sum is a prime number. It turned out that among these four numbers, the sum of some three is a prime number and the sum of some two is a prime number. What is the smallest value that the sum of these four numbers can be equal to? Urgently help!

4

Step-by-step explanation:

the image of (6, 9) under a dilation is (4, 6). the scale factor is

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
