Answer:
x - 3 > 15 ;
x > 18
Step-by-step explanation:
Given a number, x
3 less than x ; x - 3
3 less than x is more than 15
The inequality expression becomes ;
x - 3 > 15
We can solve for X ;
x - 3 > 15
Add 3 to both sides ;
x - 3 + 3 > 15 + 3
x > 18
(13 + 4i) + n = 0
13 + 4i= -n
-13 - 4i=n
D) -13-4i
Answer:
Therefore,
Step-by-step explanation:
Let the Width of rectangle be 'x' cm.
Then the length of a rectangle will be (x + 5) cm.
Area of rectangle given is 84 cm squared.
To Find:
Length = (x+5) = ?
Width = x = ?
Solution:
We have area of rectangle given as
Substituting the given values we get
On factorizing we get
Therefore,
Therefore,
Answer:
the first and last ones
Step-by-step explanation:
The equation of hyperbola is
where a is the distance from the center of hyperbola to the vertex of hyperbola.
From the diagram it is seen that the center of hyperbola is at the origin O(0,0) and the vertex of hyperbola is at the point (150,0). Then the distance a=150.
Hyperbola passes through the point (180,100), so its coordinates satisfy the hyperbola equation:
Therefore, the hyperbola equation is
