Step-by-step explanation:
To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: 
Solving for y:
because 
or 
So on interchanging the variable, we get the equation:
Answer: I don’t think so, it’s multiple choice.
Step-by-step explanation: A. =−2−20 B. =2−8
C. =−2−1 D. =2−20
Answer:
Option (c) is correct.
Step-by-step explanation:
See the attached figure.
Here, x + y = 10 cm. ............ (1)
The height h divides the whole right triangle into two different right triangles.
If we consider the height as h, then applying Pythagoras Theorem,
h² = 6² - x² {From small triangle} ........... (2)
Again, from large triangle we can write,
h² = 8² - y² .............. (3)
Now, from equation (2) and (3) we can write
6² - x² = 8² - y²
⇒ 36 - x² = 64 - (10 - x)² {From equation (1)}
⇒ 36 - x² = 64 - 100 - x² + 20x
⇒20x = 72
⇒ x = 3.6 cm.
So, from equation (1) we get, y = 10 - 3.6 = 6.4 cm.
Therefore, option (c) is correct. (Answer)
Answer:
$ 6.24
Step-by-step explanation:
(16.87 - 16.35) x 12 = 6.24
Answer:
X = 9
92 + 34 + 54 = 180 degrees
Step-by-step explanation:
180-14x + 92 + 3x + 7 = 180
-11x + 99 = 180 - 180
99 = 11x
X = 9
