Answer:
The equilibrium quantity is 26.4
Step-by-step explanation:
Given


Required
Determine the equilibrium quantity
First, we need to determine the equilibrium by equating Qd to Qs
i.e.

This gives:

Collect Like Terms


Solve for P


This is the equilibrium price.
Substitute 2.4 for P in any of the quantity functions to give the equilibrium quantity:



<em>Hence, the equilibrium quantity is 26.4</em>
Answer:
Undefined
Step-by-step explanation:
m = Δy / Δx
m = (12 − -8) / (-6 − -6)
m = 20 / 0
m = undefined
The slope is undefined.
Correct Answer:
Option 3: <span>The quadratic function has two distinct real zeros.
The function is quadratic, therefore it can have only 2 zeros. The knowledge of x-intercepts is needed to determine the zeros, y-intercepts has nothing to do with the zeros of a function. The given function has 2 unique x-intercepts, so according to the fundamental theorem of algebra, this function has 2 distinct real roots as number of distinct real roots are equal to the number of x-intercepts. Therefore, option 3 is the correct answer. </span>
You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.
3 (x2 + 10x + 25)
Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2
