Answer:
a) <em>Slope of the line m = ∞</em>
<em>b) Slope of the line m =0</em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<u><em>Step(i):-</em></u>
<em>Given points are ( 7,7) and (7,-8)</em>
<em>Slope of the line</em>
<em> </em><em />
<em> </em><em />
<em> m = ∞</em>
<u><em>Step(ii):-</em></u>
Given points are (-6,7) and (9,7)
<em>Slope of the line</em>
<em> </em><em />
<em> </em><em />
<em>Slope of the line m =0</em>
When you've got a squares bracket, this simply becomes the bracket twice, therefore, (r+s)2 becomes (r+s)(r+s)
You've then go to use FOIL, and this gives you r^2+rs+sr+s^2, and this cannot be simplified any further.
Therefore, the product of this is r^2 + s^2 + rs + sr
Hope this is what you're looking for :)
We know that
The triangle inequality<span> states that for any </span>triangle, t<span>he sum of the lengths of any two sides of a </span>triangle<span> is greater than the length of the third side
</span>so
case <span>A. 81 mm, 7 mm, 6 mm
6+7 is not > 81
case </span><span>B. 81 mm, 7 mm, 72 mm
72+7 is not > 81
case </span><span>C. 81 mm, 7 mm, 88 mm
81+7 is not > 88
case </span><span>D. 81 mm, 7 mm, 77 mm
81+7 is > 77------> ok
77+7 is > 81-----> ok
81+77 is > 7-----> is ok
the answer is the option
</span>D. 81 mm, 7 mm, 77 mm
-6.4 – 4(-2.8)
-6.4 – - 11.2 = 4.8
Your answer is B: 4.8
To get the equivalent of 3/5, multiply both the numerator and denominator by the same number. So, multiply 3/5 by 2 and you will get 6/10. Multiply 3/5 by 3 and you will get 9/15. <em><u>The equivalent fractions of 3/5 are 6/10 and 9/15.</u></em>
Hope it helps :)
