I will have "x" represent the unknown number, or you could use a "?", doesn't matter.
[8 is less than or equal to (≤) the quotient (÷) of a number and -4, so the number is being divided by -4]
If you need to solve this, you need to isolate/get the variable "x" by itself in the inequality:
Multiply -4 on both sides to get rid of the fraction and get "x" by itself
When you multiply/divide by a negative number, you flip the sign (< >)
-32 ≥ x [-32 is greater than or equal to x, or x is less than or equal to -32]
The attached image represents the foci of the hyperbola
<h3>How to determine the foci?</h3>The equation of the hyperbola is given as:
Rewrite as:
A hyperbola is represented as:
This means that:
h = 0
k = 0
b = 25
a = 60
Next, calculate c the distance from the center to the focus using:
This gives
Evaluate
This means that:
Foci = (0, -√2975) and (0, √2975)
