Answer:
Option C 
Step-by-step explanation:
Let
x ----> the cost of the concert ticket
we know that
The total cost to be no more than $4 Above $80
so
Solve for x
The total cost to be no more than $4 below $80
so
Solve for x
therefore
The inequality that represent this problem is
<u><em>Verify</em></u>
<em>First solution (positive case</em>)
Solve for x
----> is ok
<em>Second solution (negative case)</em>
Multiply by -1 both sides
Solve for x
---> is ok
Remember that
is equivalent to
Because is a absolute value
Solutions are 3 and - 5.
Step-by-step explanation:
Step 1:
Given equation is 3x² + 6x = 45. Factorize the equation to get the solutions.
⇒ 3x² + 6x - 45 = 0
⇒ x² + 2x - 15 = 0
⇒ x² + 5x - 3x - 15 = 0 (Product and Sum Method where product of coefficients = - 15 and sum = 2)
⇒ x (x + 5) - 3(x + 5) = 0
⇒ (x - 3)(x + 5) = 0
⇒ x = 3, - 5
