Answer:
A: 12
Step-by-step explanation:
Using the pythagoreom theorem, a^2+b^2=c^2. We can plug in the lengths of 5 and 13 which is 5^2+b^2=13^2. Now we can square the numbers to get 25+b^2=169. Subtract 25 from 169 to get 144. Now find the square root of 144 which is 12.
The triangle at top has a perimeter of 5, 12, and 13. The square has a perimeter of 29, 12, 29, and 12. If you add all those up you get 112
The answer is they are reciprocal.
(1) Express both equations in the slope-intercept form: y = mx + b, where m is slope:
<span> 8x - 9y = 5
9y = 8x - 5
y = 8/9x - 5/9
m1 = 8/9
</span><span>9x - 8y = 1
8y = 9x - 1
y = 9/8x - 1/8
m2 = 9/8
So, m1 = 8/9 and m2 = 9/8. They are reciprocal</span>
The answer is H. positive non-linear, because the dots are gradually increasing in height but not in a strait line so its not linear
