14. For how many ordered pairs of positive integers (x,y) is 2x+3y < 6
A. 1
B. 2
C. 3
D. 5
E. 7</p>
<p>im sorry but i dont have the bb, so i cant answer the first. but the second is 1.option a. since 2+3 is 5 and is less than six by one, the only ordered pair of integers that cld possiblt fit in are 1 and 1, to give 5 which is less than six. any other values will give an answer greater than 6 except 0 which is not a positive integer.</p>
<ol>
<li>Because the lines are parallel then 50 + (the angle between x and 50) is equal to 80, which means the angle between x and 50 is 30.</li>
</ol>
<p>180 - 30 = 150.</p>
