Solve the equation using inverse operations. Check your solutions. In you final answer, include all of your work
-X²= - 36
On a chapter test, Stephanie uses the rules of equation solving and inverse operations to solve the cubic equation below. The directions on the test are not very specific; however, they do say to give an exact solution. Stephanie is not sure if she should submit a decimal approximation or a simplified radical as the answer.
4x³=756
What recommendation can you make to Stephanie regarding her answer to the cubic equation above? In your recommendation, explain what the term "exact" indicates with regards to the solution.
Solve the cubic equation from Stephanie’s test. Submit two solutions for the equation- a) your answer as a decimal approximation, rounded to the nearest hundredth, and b) as a simplified radical. Use substitution to check each version of your solution in the original equation.
After solving the test question and checking both the decimal solution and the simplified radical form, would you change your recommendation (in Part 1) to Stephanie regarding the format of her answer? Use complete sentences to explain your reasoning.
Answer: The answer is -6.
Step-by-step explanation:
The first step in solving -X²= - 36 is to simplify the expression. Then, divide both sides by the same factor. You'll get X² - 36 = 0.
After that, you need to use the quadratic formula. Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula. a=1, b=0, and c=-36.
Finally, you need to simplify the expression. First, evaluate the exponent. Then multiply the numbers. After that, Add the numbers and evaluate the square root. Add zero, and then multiply the numbers again. You get +12/2, which simplifies into X = 6. Add the negative, and you get X = -6.
I hope it helped! :)

Mrs. Gomez is buying a triangular table for the corner of her classroom. The side lengths of the table are 5 feet, 3 feet, and 2 feet
Is this a triangular table a right triangle?
Answer:
The answer to your problem is, D. Yes, because 2 + 3 = 5.
Step-by-step explanation:
Refer to the converse of the pythagorean theorem. We need to have both sides equal to each other to have a right triangle.
So we need to have:
[tex]a^{2} + b^{2} = c^{2}[/tex]
We would need to fill out the problem and replace A, B, and C. Which leads to either being B or D
The longest side is the hypotenuse and the value of c.
Thus the answer to our problem is, D. Yes, because 2 + 3 = 5

Answer:
X=-6 and X=0
Step-by-step explanation:
I will solve this by factoring.
Factor x(x+6)=0 into to equations: X=0 and x+6=0.
Move the 6 to the other side which will make it negative and their is nothing to do with x=0.
So the final answer is X=-6 and X=0.
Answer:
x = 0 , x = -6
Step-by-step explanation:
Zero product propertyThe equation x(x+6) = 0 can be solved using the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero.
So we can set each factor ( "x" and "x+6") equal to 0 and solve for x
Factor #1
x = 0
Factor #2
x + 6 = 0
==> subtract 6 from both sides
x = -6
Checking our workWe can now substitute the values of x into the original equation to check our work
x(x+6) = 0
==> plug in x = 0
0(0+6) = 0
==> simplify addition within parenthesis
0(6) = 0
==> multiply 6 and 0
0 = 0
x(x+6) = 0
==> plug in x = -6
-6(-6 + 6) = 0
==> add -6 and 6
-6(0) = 0
==> multiply -6 and 0
0 = 0
Both values of x satisfy the equation therefore the values of x are indeed -6 and 0

Answer: 65 advance tickets
Step-by-step explanation:
Answer:
Advance tickets sold: 30
Same-day tickets sold: 25
Step-by-step explanation:
So, let's assume that the number of advance tickets is the variable [tex]x[/tex], and the number of same-day tickets is [tex]y[/tex].
Since the cost of advance tickets is $25 dollars, we can show that using [tex]25x[/tex], and the cost of same-day tickets is $35, we can show that with [tex]35y[/tex]. The total cost of the tickets is $1625 and the total number of tickets is 55.
Now, let's form a system of equations with this information.
[tex]25x+35y=1625\\x+y=55[/tex]
Step 1: Rearrange equation so that it solves for a variable
[tex]x+y=55[/tex] can be rewritten as [tex]y=-x+55[/tex]
Step 2: Substitute
[tex]y=-x+55[/tex], so, we can write this in the first equation as: [tex]25x+35(-x+55)=1625[/tex]
Step 3: Simplify
[tex]25x-35x+1925=1625\\-10x=-300\\x=30[/tex]
So the number of advance tickets sold are 30.
Now, let's solve for the number of same-day tickets sold.
Step 4: Solve for y
Using our equation from above ([tex]y=-x+55[/tex]), we can substitute the value that we solved for ([tex]x=30[/tex]) to solve for the variable y.
[tex]y=-30+55\\y=25[/tex]
The number of same-day tickets sold are 25.

Identify the first quartile, and the third quartile of the following data.
5, 1, 4, 0, 9, 0, −8, 5, 2, 4, −1, 10, 7, −5
(VOTING BRAINLIEST FOR CORRECT ANSWER)
Answer:
Q1=0.5 Q3=6
Step-by-step explanation:
To find the quartiles, we first need to put the data set in order from smallest to largest:
−8, −5, −1, 0, 0, 1, 2, 4, 4, 5, 5, 7, 9, 10
There are 14 data points, so the median is the average of the 7th and 8th numbers, which is (2+4)/2 = 3.
Now we divide the data set into two halves, the lower half and the upper half, not including the median.
Lower half: −8, −5, −1, 0, 0, 1, 2
Upper half: 4, 4, 5, 5, 7, 9, 10
To find the first quartile, we take the median of the lower half of the data set. There are 7 numbers in the lower half, so the median is the average of the 4th and 5th numbers, which is (0+1)/2 = 0.5.
To find the third quartile, we take the median of the upper half of the data set. There are 7 numbers in the upper half, so the median is the average of the 4th and 5th numbers, which is (5+7)/2 = 6.
Therefore, the first quartile is 0.5 and the third quartile is 6.

The value of x is:
↬ 73Solution:
If two angles are supplementary, that means that the sum of their measures is 180°.
We're given 2 angles:
[tex]\sf{\angle m}[/tex][tex]\sf{\angle n}[/tex]And since they're supplementary, the following holds true:
[tex]\sf{\angle m + \angle n = 180}[/tex]
Next, we know that [tex]\sf{\angle m=34}[/tex], so we plug that in
[tex]\sf{34+\angle n = 180}[/tex]
Then, ∠n = 2x:
[tex]\sf{34+2x=180}[/tex]
Which is the same as
[tex]\sf{2x+34=180}[/tex]
Subtract 34 from each side
[tex]\sf{2x=146}[/tex]
Divide each side by 2
[tex]\sf{x=73}[/tex]
Hence, x = 73Last year at a certain high school, there were 56 boys on the honor roll and 135 girls on the honor roll. This year, the number of boys on the honor roll increased by 25% and the number of girls on the honor roll increased by 20%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answer: 18.5%
Step-by-step explanation: Last year, there were 56 boys and 135 girls on the honor roll, for a total of 191 students. This year, the number of boys on the honor roll increased by 25%, which means there are now 70 boys on the honor roll (56 * 1.25). The number of girls on the honor roll increased by 20%, which means there are now 162 girls on the honor roll (135 * 1.20).
The total number of students on the honor roll this year is therefore 70 + 162 = 232.
To find the percentage increase in the total number of students on the honor roll, we can use the formula:
percentage increase = (new value - old value) / old value * 100
Plugging in the numbers, we get:
percentage increase = (232 - 191) / 191 * 100 = 21.47%
Rounding to the nearest tenth, we get an increase of approximately 18.5%.
Hope this helps, and have a great day!

Distance from School Percent of Students
Within 1 mile 50%
Between 1 and 2 miles 78%
Between 2 and 3 miles 0.1%
More than 3 miles 21.9%
What is percentage?Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the percent sign, "%". For example, 45% (read as "forty-five percent") is equal to 45⁄100, or 0.45. Percentage can be used to express how much of something there is compared to the whole.
The given data can be represented in a table to show the percent of students who are living at each distance from the school. The table shows that 50% of the students live within 1 mile from the school, 78% of the students live between 1 and 2 miles from the school, 0.1% of the students live between 2 and 3 miles from the school, and 21.9% of the students live more than 3 miles from the school. This is happening due to the fact that the majority of students live close to the school, hence the higher percentages of students living within the shorter distances and lower percentages of students living at the longer distances.
