It could be 820 thats rounded to the nearest tenth
if its supposedto be rounded to the nearest hundred its 800
<u>Understanding:</u>
The sum of 3 times a number (i'll define it as x) and 4 means
is between -8 and 10 which means the value of 3x+4 is less than 10 and greater than -8. With that said, the inequality for that problem would be
.
<u>Solving the problem:</u>
Now we know that
, you can solve the problem by <em>subtracting 4</em> from each side then<em> dividing by 3.</em>

Perpendicular lines have slopes that are negative reciprocals. Since the slope of AB is 0/7, the reciprocal is 7/0, which is undefined.
Any line with an undefined slope is a vertical line. This will be a vertical line that passes through point B.
Vertical lines have the equation x=c, where c is a constant; since it runs through B, which has coordinates (4, 4), this means the equation is x=4.</span></span>
