Answer:
-1/cd
b = -a/cd
Step-by-step explanation:
a = -bcd
Multiplication and division are inverse operations
Multiply each side by -1/cd
a* -1/cd = -bcd * -1/cd
-a /cd = b
Answer: The graph of rectangular hyperbola represents the function f(x)=4/x.
Explanation: given function, f(x)= 4/x.
The above function shows equation of rectangular hyperbola or equilateral hyberbola.(because, it is the type of
.)
Thus, the asymptote of the given function must be perpendicular.
Moreover, if x=2, y=2, if x=-2, y=-2
If x=4, y=1, if x=-4, y=-1
Therefore, this hyperbola is passing through points (2,2), (-2,-2), (4,1) and (-4,-1).
Answer:
x = 21

- Corresponding Angles - Angles that are congruent to each other and occur with parallel lines
Step-by-step explanation:
<u>Step 1: Identify</u>
We see that the measures given are Corresponding Angles
<u>Step 2: Solve for </u><em><u>x</u></em>
- Set up equation: 8x - 7 = 9x - 28
- Subtract 8x on both sides: -7 = x - 28
- Add 28 on both sides: 21 = x
- Rewrite: x = 21
