Write 9x² - 36x = 4y² + 24y + 36 in standard form
this is a graph of a hyperbola, if this helps.
please include the steps on how you did it
Thank you!
Answer:
9·x² - 36·x = 4·y² + 24·y + 36 in standard form is;
(x - 2)²/2² - (y + 3)²/3² = 1
Step-by-step explanation:
The standard form of a hyperbola is given as follows;
(x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1
The given equation is presented as follows;
9·x² - 36·x = 4·y² + 24·y + 36
By completing the square, we get;
(3·x - 6)·(3·x - 6) - 36 = (2·y + 6)·(2·y + 6)
(3·x - 6)² - 36 = (2·y + 6)²
(3·x - 6)² - (2·y + 6)² = 36
(3·x - 6)²/36 - (2·y + 6)²/36 = 36/36 = 1
(3·x - 6)²/6² - (2·y + 6)²/6² = 1
3²·(x - 2)²/6² - 2²·(y + 3)²/6² = 1
(x - 2)²/2² - (y + 3)²/3² = 1
The equation of the hyperbola is (x - 2)²/2² - (y + 3)²/3² = 1.

Step-by-step explanation:
a football coach is trying to decide: when a team is ahead late in the game, which strategy is better?
• play the "regular" defense.
• play a "prevent" defense that guards against long gains but makes short gains easier
the coach reviews the outcomes of 100 games
compare the probability of winning when playing regular defense with the probability of winning when playing prevent defense. draw a conclusion
based on your results.
From analysis, it is seen that the probability of winning when playing regular defense is higher than the probability of winning with *prevent* defence.
How to find the probability of Winning?We will assume that a total of 100 games were reviewed.
50 games used regular defense method.
The remaining 50 games used the prevent defense method.
Out of the 50 regular defense games, 38 were win while 12 games were lose.
Out of 50 prevent defense game, 29 were win, while 21 games were lose.
Thus, the Probability of winning by regular defense is:
P(win | regular) = 38/50
P(win | regular) = 0.76
Probability of winning by playing prevent defense is:
P(win | prevent) = 29/50 = 0.58
From the above analysis we observe that the probability of winning by using the regular defense method is greater than the probability of winning by prevent defense method.
That is 0.76 > 0.58.

Diane buys candy that costs $4 per pound. She will spend more than $20 on candy. What are the possible numbers of pounds she will buy?
Use
P
for the number of pounds Diane will buy.
Write your answer as an inequality solved for p.
Answer:
12 pounds
Step-by-step explanation:
We know that the candy costs $4 per pound
We also know that he will only spend up to $48
We can represent this as an equation:
4x = 48
Where as x = number of pounds
Solve the equation to find how many pounds he can buy.
4x = 48
Divide both sides by 4
x = 12
This means that Kareem can buy 12 pounds

0.1(0.5m+6)=2
Answer:
m = 28
Step-by-step explanation:
The given expression is :
0.1(0.5m+6)=2
Step 1.
Use distributive property:
0.1(0.5m) +0.1(6) = 2
0.05 m+ 0.6 = 2
Step 2.
Subtract 0.6 both sides
0.05 m+ 0.6 -0.6= 2 -0.6
0.05 m = 1.4
or
0.5 m = 14
Step 3.
Divide both sides by 0.5
[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]
Gabi's third step is not correct. It should be m = 28 instead of m = 7.

Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the average weight of n=5 marathon runners:
[tex]\bar x=92[/tex]
Multiplying the formula by n and expanding the sum:
[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]
We are given the weighs of four of the runners:
[tex]5*92=89+95+90+90+x_5[/tex]
[tex]460=364+x_5[/tex]
Solving for x5:
[tex]x_5 = 460-364=96[/tex]
Jordin weighs 96 pounds
Renting roller blades costs a flate fee of $5 plus an additional $2.50 per hour. Write a linear equation that models this.
Answer:
Linear equation : y = 2.50h + 5
Step-by-step explanation:
Given that:
Fee for renting roller blades = $5
Per hour charges = $2.50
Let,
h be the number of hours roller blades were rented
y be the total amount
Total amount = Per hour charges * Number of hours + Flat fee
y = 2.50h + 5
Hence,
Linear equation : y = 2.50h + 5
Chase thought that only 23 people Would come to the banquet but 48 people endd up coming what was his percent error
Answer:
the percent of people that end up coming as error is 12%
Chase made a miscalculation of 52.08% percent.
What is Percentage Error?
The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.
Given that, Chase anticipated that just 23 people would attend the event; however, 48 individuals showed up.
The general formula for percentage error:
Percentage Error(%e) = ((Estimated Number – Actual Number)/ Actual number) x 100.
Hence,
Percentage error done by chase = (23 - 48) * 100/48
Percentage error done by chase = -52.08%
Therefore, the Percentage error done by chase is 52.08%
