Answer:
x = 11m
Step-by-step explanation:
The longest side is the bottom (15m). If you look at the sides you can see that the side that measures 4m is parallel with the side that measures 15m. Anytime two sides overlap to make x, we can simplify by subtracting or adding. All we need to do is subtract to find the length of x.
15 - 4 = 11m
For this case we have the following equation:
To solve we follow the steps below:
We add similar terms from the left side of the equation:
We divide between 6 on both sides of the equation:
Finally, we have to:
Answer:
Step-by-step explanation:
(A) To find inverse of f(x) = y = 1 / x - 3 :
<u>Transform in terms of x</u>
y = 1 / x - 3
x - 3 = 1 / y
x = 3 + 1 / y
<u>Exchange x with y</u> :
Therefore, g(x) is not inverse of f(x) and vice versa.
(B)
Domain of f(x) = R - {3}
Domain of g(x) = R - {0}
Answer:
k=-7
Step-by-step explanation:
2k-6-7+3k=-48
Combine like terms
5k -13 = -48
Add 13 to each side
5k-13+13 = -48+13
5k = -35
Divide by 5
5k/5 = -35/5
k =-7
Answer:
No
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.
The longest side = 61, thus
61² = 3721
12² + 60² = 144 + 3600 = 3744 ≠ 3721
Thus these sides do not form a right triangle.
