Answer:
(x + 2)² = 7
Step-by-step explanation:
We have to complete the square in the given equation
3x² + 12x = 9
3x² + 12x - 9 = 0
3[x² + 4x -3] = 0
3[x² + 2(2x) + 4 - 4 - 3] = 0
3[x² + 2(2x) + 4] - 3 × 7 = 0
3[x² + 2]² - 21 = 0
(x + 2)² = = 7
Therefore, the square form of the equation is (x + 2)² = 7
Hope this helps (:
Answer:
The correct answer is:
Negative StartFraction 9 over 4 EndFraction divided by two-thirds
i.e.
Step-by-step explanation:
We have to find equivalent expression to :
Negative 2 and one-fourth divided by negative two-thirds
i.e.
We have to convert the the mixed fraction form 
to simpler 
fraction form.
Let us learn the concept first.
Mixed fraction is combination of a whole number and a fraction.
Expression of the form 
have the following understanding:
c is the divider
b is the remainder and
a is the quotient.
To convert mixed fraction to fraction we can use the following:
Hence
i.e. the given expression is equivalent to :
Negative StartFraction 9 over 4 EndFraction divided by two-thirds
-3y = 2x - 7
when x = 0
-3y = -7
y = 7/3
y = 2 1/3(2 and 1/3)
when y = 0
2x - 7 = 0
2x = 7
x = 3.5
when x = 2
-3y = 2(2) - 7
-3y = -3
y = 1
when x = -1
-3y = 2(-1) - 7
-3y = -9
y = 3
Answer ( you can 3 of those below for your ordered pairs)
ordered pairs
(0, 7/3), (3.5, 0) (2, 1), (-1, 3)
Q= Analysts determined that a baseball team had a 25% chance of winning its next game. Which simulation could you use to answer questions about winning the game?
Answer:
<u>For this question, there is a 75% chance of loosing.</u>
<h3><em>
<u>In a similar question .........</u></em></h3>
Q= Analysts determined that a basketball team had a 50% chance of winning its next game. Which simulation could you use to answer questions about winning the game?
A<u>= the team has 50% probilty of suscseeding</u>
<u>So we should use a simulation that also has the same posiblities.
</u>
<u>
so flipping a coin can be used in this situaouion </u>
<u> as it has 2 ends each with probability 1/2. Therefore in this question answer is 50 % </u>
