Answer:
9 and -3
Step-by-step explanation:
9 and -3 are both factors of -27 since they can be multiply each other to get -27. Also, they both add up to 6.
The factors of -27 that sum up to 6 are 9 and -3
How to determine the factors of -27 that sum up to 6From the question, we have the following parameters that can be used in our computation:
Factors = -27
Sum = 6
Let the numbers be x and y
So, we have
xy = -27
x + y = 6
Let x be 9 and y be 3
So, we have
9 * -3 = -27
9 - 3 = 6
Hence, the numbers are 9 and -3

Step-by-step explanation:
mark me as brainliest ❤️
hi <3
you have to isolate the variable 'y'
to do that, just subtract 8 from both sides of the equation
thus, y = 3 - 8
giving you an answer of y = -5

Answer:
n = 25
Step-by-step explanation:
The smallest perfect square larger than 144 = 12² is 169 = 13². As it happens, the difference of these squares is 25, a number divisible by 5.
So n=25 will make all of the expressions have values that are natural numbers.

n = 0 would make all of them integers, but 0/5 = 0 is not a natural number.

Equations are used to show the relationship between variables (usually x and y). The true statement about f(x) is that the range of f(x) is [tex]y \ge -8[/tex]
Given that:
[tex]f(x) = 2(x - 2)^2 - 8[/tex]
To identify the true statement, I will make use of graphical method.
See attachment for the graph of [tex]f(x) = 2(x - 2)^2 - 8[/tex]
From the attached graph, we can see that the graph as a minimum at:
[tex](x,y) = (2,-8)[/tex]
And it opens upward.
This implies that the minimum y-value of f(x) is at -8, and it has no maximum.
In other words, the range of the function is:
[tex]f(x) \ge -8[/tex]
Hence, the true statement is option (a):
The range of f(x) is [tex]y \ge -8[/tex]

Of the 121,301,000 men in the U.S., 3.38% didn’t complete 9th grade. How many men is this?
Answer:
4099973
Step-by-step explanation:
I hope this is correct! :)
Sorry if I'm wrong...
Approximately 4,100,938 men in the U.S. didn't complete 9th grade. To find out how many men in the U.S. didn't complete 9th grade, we can use the percentage given and calculate it as follows: Number of men who didn't complete 9th grade = (Percentage of men who didn't complete 9th grade / 100) * Total number of men in the U.S.
Given:
Percentage of men who didn't complete 9th grade = 3.38%
Total number of men in the U.S. = 121,301,000
Let's calculate:
Number of men who didn't complete 9th grade = (3.38 / 100) * 121,301,000
Number of men who didn't complete 9th grade ≈ 4,100,938
So, approximately 4,100,938 men in the U.S. didn't complete 9th grade.

The sum of the two girls' ages is 24, and the difference between their ages is 6. What are the girls' ages?
First, let's create two variables to express the girls' ages.
x=age of girl 1
y = age of girl 2
Now, let's create our expressions
x+y = 24
x-y=6
Let's solve by elimination
2x = 30
Divide both sides by 2
x=15
We can plug 15 in for x into one of our expressions
15 + y = 24
Subtract both sides by 15
y = 9

Answer:
(y – 1) = -⅔(x + 6)
Step-by-step explanation:
Given:
Slope of -⅔Point/Coordinate of (-6, 1)To find the point slope form, first use the formula:
(y – y_1) = m(x – x_1).
Where (x_1, y_1) is a given point, and m is the slope of the line.
The next and final step is to substitute the given information into the equation like this.
(y – y_1) = m(x – x_1) →
(y – (1)) = (-⅔)(x – (-6)).
Then simplify:
(y – (1)) = (-⅔)(x – (-6)) → (y – 1) = -⅔(x + 6).
You can also verify that the information is correct if you replace the coordinate for x and y values, so that the equation is true like 0 = 0, or where both sides are the same.
(-6, 1) → (y – 1) = -⅔(x + 6) →
(1 – 1) = -⅔(-6 + 6) → 0 = 0 ✓
