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.

1.) 25 - 3x = 88
2.) -11 = 7 - x
3.) 95 = -4 + 33x
Answer: hope this helps ♡
1.) x = -21
2.) x = 18
3.) x = 3
Step-by-step explanation:
(minus&minus = plus) (minus&plus = minus) (plus&minus = minus)
1.) 25 - 3x = 88
25 - 25 - 3x = 88 - 25
-3x = 63
-3x ÷ 3 = 63 ÷ 3
-x = 21 → x = -21
2.) -11 = 7 - x
-11 - 7 = 7 -7 -x
-18 = -x
18 = x → x = 18
3.) 95 = -4 + 33x
95 + 4 = -4 + 4 + 33x
99 = 33x
99 ÷ 33 = 33x ÷ 33
3 = x → x = 3

Step-by-step explanation:
mangos: m = 108
portugals: p
oranges: o = 3p
108 + p + 3p = 540
108 + 4p = 540
4p = 540-108 = 432
p = 432/4 = 108
o = 3p = 3(108) = 324
324/108 = 3 there are 3 times more oranges than portugals

Calculate the volume of a cone with a height of 6 inches and a diameter of 6 inches.
Leave your answer in terms of PI
Answer: Volume ≈ 56.55
Step-by-step explanation:
56.54867 is the answer, but I rounded it. I hope this helped! :)
Answer:
18π cubic inches
Step-by-step explanation:
First, we need to find the radius of the cone, which is half of the diameter.
radius = diameter/2 = 6/2 = 3 inches
The formula for the volume of a cone is:
V = 1/3 × π × r^2 × h
where r is the radius of the base of the cone, and h is the height of the cone.
Substituting the values we get:
V = 1/3 × π × 3^2 × 6
V = 1/3 × π × 9 × 6
V = π × 18

Identify the least value, first quartile, median, third quartile, and greatest value of the data.
5, 1, 4, 0, 9, 0, −8, 5, 2, 4, −1, 10, 7, −5
Answer:
least value=-8, Q1=-0.5, median=3, Q3=5, greatest value=10
Step-by-step explanation:
To find the least and greatest values, we simply look at the numbers in the data set and see that the least is -8 and the greatest is 10.
To find the first quartile, median, and third quartile, we need to put the data in order from least to greatest:
-8, -5, -1, 0, 0, 1, 2, 4, 4, 5, 5, 7, 9, 10
There are 14 numbers in the data set, so the median is the average of the 7th and 8th numbers, which is:
(median) = (2+4)/2 = 3
To find the first quartile, we need to find the median of the lower half of the data set. The lower half includes the first 7 numbers:
-8, -5, -1, 0, 0, 1, 2
The median of this lower half is the average of the 3rd and 4th numbers:
(first quartile) = (-1+0)/2 = -0.5
To find the third quartile, we need to find the median of the upper half of the data set. The upper half includes the last 7 numbers:
2, 4, 4, 5, 5, 7, 9, 10
The median of this upper half is the average of the 4th and 5th numbers:
(third quartile) = (5+5)/2 = 5
So the least value is -8, the first quartile is -0.5, the median is 3, the third quartile is 5, and the greatest value is 10.

Consider the set of all 4-digit numbers. How many have at least one zero digit?
Answer: 2439
I think what you want is, all the four digits numbers which can be formed with the help of the ten digits i.e. {0, 1, 2, 3, ……. … … , 9} which contains 0 at least once in it. Taking this way, to find all the required numbers, we may proceed as follows;
To form four digits numbers means to fill up four vacant places say X, X, X, X with the help of these ten digits. Since nothing has been said about repetition or non-repetition of the digits, so I take it that repetitions of digits are allowed so that all possible numbers come into consideration. Now;
1st vacant place can be filled up by 9 ways (as 0 can not come to this place otherwise number formed will be of three digits). Further,
2nd, 3rd and 4th vacant place each can be filled up by 10 ways (each)(as 0 may also come to these places).
Hence, total no. of numbers of four digits = 9 .10.10.10 = 9000.
Next the total no. of numbers of four digits without zero at any place = 9. 9. 9. 9 = 6561.
Therefore, required no. Of numbers of four digits having at least one zero = 9000 - 6561 = 2439.

The measures of the legs of a right triangle both measure 7 yards. What is the length of the hypotenuse? Round your answer to the nearest tenth.
A. 7 yards
B. 9.8 yards
C. 9.9 yards
D. 10 yards
Answer: 9.9 yards
Step-by-step explanation: Since we know that the legs of the right triangle both measure 7 yards, we can use the Pythagorean theorem to find the length of the hypotenuse, which is the longest side of the right triangle.
According to the Pythagorean theorem, the square of the hypotenuse equals the sum of the squares of the legs. In this case, we have:
c^2 = 7^2 + 7^2 c^2 = 49 + 49 c^2 = 98
To find the length of the hypotenuse, we need to take the square root of both sides of the equation:
c = √98
Using a calculator, we can find that √98 is approximately 9.9. Therefore, the length of the hypotenuse is approximately 9.9 yards.
The answer is C. 9.9 yards.

Create a number line that represents the solution set of the inequality w divided by 7 > 38. Show all your work
Answer:
Step-by-step explanation:
To represent the solution set of the inequality w divided by 7 > 38 on a number line, we first need to isolate the variable w:
w/7 > 38
w > 7 x 38
w > 266
This means that any value of w greater than 266 satisfies the inequality.
We can represent this on a number line by marking a closed circle at 266 (since the inequality is not inclusive of this value), and drawing an arrow to the right to indicate all values greater than 266:
<--o======(266)---------------->
This represents the solution set of w/7 > 38.

What do we divide the numerator and denominator by to simplify
12/30 to lowest terms? (What is the largest number we can divide both the numerator and denominator by?)
Answer:
The factors of 12 are 1, 2, 3, 4, 6, and 12.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
The largest number that both 12 and 30 have in common is 6.
So, we can divide both the numerator and denominator by 6:
12/30 ÷ 6/6 = 2/5
Therefore, 12/30 simplified to lowest terms is 2/5.
Answer:
Divide the numerator and denominator by 6:
[tex] \frac{12}{30} = \frac{2}{5} [/tex]
Step-by-step explanation:
12 = 2 × 2 × 3
30 = 2 × 3 × 5
GCD of 12 and 30 = 2 × 3 = 6

Answer: y=-7
Step-by-step explanation:
solve 5x+2y =-4 for x
Add -2y to both sides
divide both sides by five
substitue -2/5y +-4/5 for x in 3X +10 Y equals -64
44/5 + -12/5 equals -64
Simply both sides
add 12/5 to both sides
Divided by 44/5
y= -7
Answer:
Hence The Value of Y=-2 at the intersecting point
Step-by-step explanation:
Given the equation
5x+2y=-4 and 3x+10y=-64
are intersected at X=2 to find the value of y
solution the equation 5x+2y=-4 and 3x+10y=-64
are intersect at x=2 means x=2 satisfied both equations so x=2 put in the
1st equation
5 x 2+2y=-4
2y=-4 -1 0= -14
y= -7
