An expression which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula is: expression A. Therefore, the correct answer option is A.
<h3>What is a quadratic equation?</h3>
A quadratic equation can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph. In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c = 0
Mathematically, the quadratic formula is modeled or represented by this mathematical expression:

From the information provided, we have the following values;
0 = -3x² - 2x + 6
Where:
a = -3
b = -2
c = 6
Substituting the values into the quadratic formula, we have;

Answer:
y = 7 - 2x/3
Step-by-step explanation:
Make the y alone, so 3y = -2x+21
Divide everything else by 3, so y = -2x/3 +7
You end with the answer of y= 7-2x+3

HEY BABE
Step-by-step explanation:
Answer:
Step-by-step explanation:
60 sec= 1 min
60min=1hour
24hours=1day
7days=1week
52 weeks =1 year
24x7= 168hours in a week
168hours x 52 =8736 hours in a year
8736x60=524160mins
524160mins= 1 year
the heart beats 103680 in a year
the heart will beat 524160/103680=5.05555555556 in a minute
I can only guess that you meant to write
12 + 3 = 3 + 12
which would be the commutative property of addition.
