Answer:
5
Step-by-step explanation:
Let's convert those words into a line in slope intercept form. From what you said, the equation of a line perpendicular to the desired one is is . The slope of this line is , since the slope intercept form is y=mx+b, where m is the slope and b is the y intercept. The slope of a line perpendicular to this one is the negative reciprocal, or . Since the line passes through the point (3,1), we can count backwards to find where the y intercept is (where x is 0). Since the slope is negative, for every unit you go backward on the x axis, you rise 4/3 on the y axis. Going backwards 3 units, then, will take you up 12/3, or 4 units. Adding this to the initial x value of the point of 1, you get a y value of 5. Hope this helps!

<u>Solution</u>:
<em>7/(-2.5 + 8.5) + {0.6 (8 + 13)}/-0.2</em>
= 7/6 + (12.6/-0.2)
= 7/6 - 63
= (7 - 378)/6
= -371/6
<em>(OR)</em>
= 61.8333... <em>(Decimal representation of -371/6 is non-terminating & recurring)</em>
D:3, 5, 7, 9, 11
R: -2, 2, 6, 10, 14
