Answer:
f(x) = 3x - 7
Step-by-step explanation:
Let the independent variable of a function is 'y' and dependent variable 'x'.
Therefore, function will be in the form of y = ax - b
Now statement given in the question states that "The output is 7 more than 3 times the input."
That means y is 7 less than 3 times of x.
y = 3x - 7
Rewrite this equation in the form of a function.
f(x) = 3x - 7

An isotope of cesium-137 has a half-life of 30 years. If 5.5 grams of cesium-137 disintigrates over a period of 105 years, how many grams of cesium-137 would remain? Round your answer to the thousandths place.
Answer:
0.484 g
Step-by-step explanation:
N/No = (1/2)^t/t1/2
No = mass of cesium-137 originally present
N= mass of cesium-137 at time t
t1/2= half life of cesium-137
t = time taken
N/5.5=(1/2)^105/30
N/5.5=(1/2)^3.5
N/5.5= 0.088
N = 5.5 * 0.088
N= 0.484 g

Step-by-step explanation:
Which expression represents all the solutions to the inequality
3(2x - 8) > 4x + 26?
Answer:
x > 25
Step-by-step explanation:
3(2x−8)>4x+26
Step 1: Simplify both sides of the inequality.
6x−24>4x+26
Step 2: Subtract 4x from both sides.
6x−24−4x>4x+26−4x
2x−24>26
Step 3: Add 24 to both sides.
2x−24+24>26+24
2x>50
Step 4: Divide both sides by 2.

If x=5 and y=−2, evaluate the following expression:20−5y+2x
Step-by-step explanation:
20−5y+2x
20-5(-2)+2(5)
20+10+10=40
Answer:
20 − ( 5 ) ( −2 ) + ( 2 ) ( 5 )
= 20 − ( −10 ) + ( 2 ) ( 5 )
= 30 + ( 2 ) ( 5 )
= 30 + 10
= 40

Answer: 60 is the answer.
Step-by-step explanation: We can use the total sum, 180.
To get the missing angle, add the 2 angles, 60 and 60.
60 + 60 = 120.
Then subtract from 180.
180 - 120 = 60.
Hence, 60 is the answer.
Let me know if you have any questions.
~ Lily, from Brainly.
Note to asker: Write this down!
To find 1 missing angle:
A1 + A2 = TA - 180 = X (A1 = Angle1)
I am stugling with algebra (because of zoom classes) and have multiple questions, please answer as many as you can. Thank you!

Answer:
x = 7x = 4x = 5x = 2Step-by-step explanation:
The general steps are ...
look at what you haverewrite the equation so the variable terms are on one side and the constant terms are on the other side of the equal sign; collect termsdivide by the coefficient of the variableIt is generally convenient to put the variable terms on the side of the equation having the largest (most positive) variable term. You do the rearranging by subtracting the terms you don't want. Any operation is performed on both sides of the equation.
__
1) 3x + 7 = 4x
We observe the largest x-term is on the right, and the only constant term is on the left. We can subtract the x-term 3x to eliminate it from the left side
3x +7 -3x = 4x -3x
Combining like terms gives ...
7 = x . . . . . this is the solution
__
2) x +2 +2x = x + 10
We observe x-terms and constants on both sides of the equation. First of all, we will combine like terms.
3x +2 = x +10
The largest x-term is on the left, so we choose to subtract x (the x-term on the right)
3x -x +2 = x -x +10
2x +2 = 10
We don't want the constant on the left, so we subtract 2.
2x +2 -2 = 10 -2
2x = 8 . . . . . . . . . . combine like terms
Now, we divide by the coefficient of x.
2x/2 = 8/2
x = 4 . . . . . . the solution
__
3) x +3x = x + x + 10
4x = 2x +10 . . . . . . . combine like terms
2x = 10 . . . . . . . . . . . subtract 2x
x = 5 . . . . . . . . . . . . . divide by 2
__
4) 2x +3 + 3x = x + 11
5x +3 = x +11 . . . . . . . . combine like terms
4x +3 = 11 . . . . . . . . . . . subtract x
4x = 8 . . . . . . . . . . . . . . subtract 3
x = 2 . . . . . . . . . . . . . . .divide by 4
_____
Learn to identify and combine like terms. Use addition or subtraction to eliminate terms you don't want. Use multiplication or division to eliminate coefficients you don't want. Whatever you do to one side of the equation must also be done to the other side of the equation. (In the above, we use "subtract ..." to mean "subtract ... from both sides of the equation," for example.)
Serenity has a toy car collection. She keeps some in a display case and the rest on the
wall.
104
of her toy cars are on the wall, and 74% of her toy cars are in the display
case. What is the total number of toy cars in Serenity's collection?
If 74% are in the display, then 100% - 74% = 26% are hung on the wall.
This means 104 cars is 26% of her collection.
To find the total collection divide the number on the wall by the percentage of the collection:
104/0.26 = 400
The total number of her collection is 400 cars.

vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his uncle.what are the ages of vamis brother, uncle and aunt? what will be the age of his uncle 6 years from now
pls send the ans fast
Step-by-step explanation:
Vamsi is X years old
Vamsi = X
his brother is 3 years elder to him
Brother = X + 3
his uncle is 4 times his age
Uncle = 4X
his aunt is 5 years younger than his uncle
Aunt = Uncle - 5
what will be the age of his uncle 6 years from now
= 4X + 6
what are the ages of vamis brother, uncle and aunt?
Assume Vamis = 15 years
Brother = X + 3 = 15 + 3 = 18
Uncle = 4X = 4 * 15 = 60
Aunt = Uncle - 5 = 60 - 5 = 55
what will be the age of his uncle 6 years from now
Uncle = 4X + 6 = 60 + 6 = 66
