<h2>quadratic equation</h2>
the solution of the quadratic equation is twofold, to find the solution, you can factor it first.
4x² + 8x + 3 = 0
4x² + 6x + 2x + 3 = 0
2x(2x + 3) + 1(2x + 3) = 0
(2x + 3) (2x+1) = 0
2x+3=0 or 2x+1=0
x=-3/2 x=-1/2
<em><u>You can try to prove that the x value above will produce 0</u></em>
• first x = -3/2
= 4(-3/2)² + 8(-3/2) + 3
= 9 - 12 + 3
= 0 (true ✔️)
• second x = -1/2
= 4(-1/2)² + 8(-1/2) + 3
= 1 - 4 + 3
= 0 (true ✔️)
It's D<span>
the inverse is basically the operation that will undo your original function

D
uses the the formula y=mx+b and m is the slope. b is the y intercept.
Answer:
8-3i
Step-by-step explanation:
The complex additive inverse is the number we need to add so that we get zero. It is the negative of the number.
a + bi is –(a + bi) = –a – bi.
a+bi + (-a+-bi) = a-a + bi-bi = 0
The complex additive invers of -8+3i is
-(-8+3i)
Distribute the negative
8 -3i
Answer:
(15, 12)
Step-by-step explanation:
Let's generate two systems of equations that fit this scenario.
Number of trips to the airport = x
Number of trips from the airport = y
Total number of trips to and from the airport = 27
Thus:
=> equation 1.
Total price for trips to the Airport = 14*x = 14x
Total price of trips from the airport = 7*y = 7y
Total collected for the day = $294
Thus:
=> equation 2.
Multiply equation 1 by 7, and multiply equation 2 by 1 to make both equations equivalent.
7 × 
1 × 
Thus:
=> equation 3
=> equation 4
Subtract equation 4 from equation 3
-7x = -105
Divide both sides by -7
x = 15
Substitute x = 15 in equation 1


Subtract both sides by 15


The ordered pair would be (15, 12)
