The rule that maps each domain value to its range value is f(x)= ___x.
Answer:
f(x) = 1/2x
Step-by-step explanation:
When x = -4 the output is -2
We are dividing by 2
When x = -2 the output is -1
f(x) = 1/2 x
Check when x = 2
f(2) = 1/2 (2) =1

-5 ≤ 1 - 2x < 9
Let's first break this down into two different inequalities.
1 - 2x ≥ -5
Subtract 1 from both sides.
-2x ≥ -6
Divide both sides by -2
x ≤ 3
Now, let's do the second inequality.
1 - 2x < 9
Subtract 1 from both sides.
-2x < 8
Divide both sides by -2
x > 4
let's combine each inequality to get our reduced compound inequality.
-4 < x ≤ 3
To plot this, put a hollow point at -4. A hollow point looks something like the letter o.
And put the second point at 3. This time, fill in the point so it looks whole.
Now, connect your points.
It should look something like this:

K = 4a + 9ab solve for a
Answer:
[tex]a=\frac{K}{4+9b}[/tex]
Step-by-step explanation:
[tex]K=4a+9ab[/tex]
Switch sides:
[tex]4a+9ab=K[/tex]
Factor out a:
[tex]a\left(4+9b\right)=K[/tex]
Divide both sides by: [tex](4+9b)[/tex]
[tex]\frac{a\left(4+9b\right)}{4+9b}=\frac{K}{4+9b}[/tex]
[tex]a=\frac{K}{4+9b}[/tex]

7p + 3(-6p + 2) > 7p+9+1
Someone help me
Answer:
p > -0.2222
Step-by-step explanation:
7p + 3(-6p + 2) > 7p + 9 +1
7p + (3*-6p + 3*2) > 7p + 10
7p - 18p + 6 > 7p + 10
-11p - 7p > 10 - 6
-18p > 4
p > 4/-18
p > -0.2222

First person to answer gets brainliest Find the domain and range of the following absolute value functions f(x)= |-2x|+7
Answer:
domain: all real numbers
range : y ≥ 7
Step-by-step explanation:
The domain is the values that x can take
X can take any value so the domain is all real numbers
The range is the values that y can take
The smallest value for the absolute value is 0
0+7 =7 so the smallest value for y is 7
range is y ≥ 7

Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, what is Stephanie's age?
Answer: Stephanie is 15
Step-by-step explanation:
because you can do 24 divided by 2 which equals 12 then add three to 12 and you get 15.
you're welcome! plz lmk if i'm wrong XD
Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, then Stephanie's age is 15 years.
To find Stephanie's age, we need to follow the given information that her age is 3 years greater than half of her sister's current age.
First, we find half of her sister's age: Half of 24 = 24 / 2 = 12
Next, we add 3 years to half of her sister's age: 12 + 3 = 15
Therefore, Stephanie's age is 15 years.
Age can be used in mathematical equations and word problems to solve for unknowns or to establish relationships between different quantities. For example, age-related math problems might involve scenarios such as Finding someone's age given their birth year and the current year, Calculating the average age of a group of people and Determining the age difference between two individuals based on their birth years.

Answer:
x=20
Step-by-step explanation:
Ques5) x value is 20 because 3x+6x=180
=>9x=180
=> x=180/9
=> x=20
Ques6) 6x= 6*x which is equal to 6*20=120
Ques7) 3x=3*x which is equal to 3*20=60
This is correct because 120+20=180 which is a straight angle given in the question. Hope this helped, Thank you.

Step-by-step explanation:
Point I is on line segment \overline{HJ}
HJ
. Given HI=2x,HI=2x, HJ=4x,HJ=4x, and IJ=4x-10,IJ=4x−10, determine the numerical length of \overline{IJ}.
IJ
.
Answer:
IJ = 20
Step-by-step explanation:
Point I is on the lines segment HJ. So,
HJ = HI + IJ
Putting all the given values, we get :
4x=2x+4x-10
Taking like terms together, we get :
-2x=-10
x=5
Put the value of x in IJ = 4x-10
IJ = 4(5)-10
IJ = 20
Hence, the value of IJ is 20.

Find the volume of the sphere. Use 3.14 for it. Round to the tenths if necessary. Don't forget to include your
label in the answer. Use ^ to show an exponent.
Hey there! I'm happy to help!
First let's find the radius. The radius is half of the diameter.
9/2=4.5
Here's how to find the volume of any sphere.
You cube the radius.
4.5³=91.125
You multiply by 3.14
91.125(3.14)=286.1325
And finally we multiply by 4/3.
286.1325(4/3)=381.51
We round to the nearest tenth, giving us a volume of 381.5 in^3.

answerers about Caca Andika from IndonesiaFind the value of x in the triangle shown below help please!!
Step-by-step explanation:
Hey there!!
It 's so simple.
You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)
So,
77° + 31° + x = 180°
x + 108° = 180°
x = 180° - 108°
Therefore the measure of angle x is 72°.
