V (x) = (18 - 2x) (24-2x) (x)
what is a reasonable domain for V in this context?
Answer:
What are you asking?
Step-by-step explanation:
The domain of the given expression is all real numbers.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
The given function is v(x) =(18-2x)(24-2x)(x).
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation: (-∞, ∞)
Set-Builder Notation: {x|x∈R}
Therefore, the domain of the given expression is all real numbers.

NEED ANSWERS ASAP!!! - How do you find the value of x??
Answer: Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
Answer:
equal the equations
(x+20)=(2x-10)
then answer the equation
Step-by-step explanation:
what is the value of x in the triangle??
Answer:
x=40°
Step-by-step explanation:
Every triangles area equals 180
75+65=140
180-140=40
Answer:
40
Step-by-step explanation:
All angles in a triangle add up to 180°.
65° + 75° + x° = 180
140° + x° = 180°
-140 -140
x° = 40°

The height of the doorway is ____ inches.
2(6x + 1) - 4(x - 5) = -2
Answer:
x=−3
Step-by-step explanation:
2(6x+1)−4(x−5)=−2
Step 1: Simplify both sides of the equation.
2(6x+1)−4(x−5)=−2
(2)(6x)+(2)(1)+(−4)(x)+(−4)(−5)=−2(Distribute)
12x+2+−4x+20=−2
(12x+−4x)+(2+20)=−2(Combine Like Terms)
8x+22=−2
8x+22=−2
Step 2: Subtract 22 from both sides.
8x+22−22=−2−22
8x=−24
Step 3: Divide both sides by 8.
8x/8=−24/8
Jaden is saving money to buy a bike that costs $290. He has saved $140 so far. He plans on saving $25 each week. Write and solve an equation to determine in how many weeks (identify the question) Jaden will have enough money to buy the bike.
What does the variable in question 4a represent?
Answer:
25w+140=290
He will have enough money in 6 weeks
w represents the amount of weeks
Step-by-step explanation:
25w+140=290
$25 every week + the original $140 = the total needed $290
Answer:
140 + 25w = 290
w = 6
Step-by-step explanation:
Goal: $290
Currently have $140
Saving $25 each week (variable)
Start with your given amounts :
(base) 140 + 25w (variable solving for) = 290 (goal you want equation to equal)
w stands for the amount of weeks for the goal to be reached
Solve:
140 + 25w = 290
subtract 140
25w = 150
divide 25
w=6
Double check (optional but suggested)
140 + 25 (6) = 290
140 + 150 = 290
290 = 290
correct

Part A: find the value for x:
Part B: what is the value of angle A?
Answer:
part A:
If ABC is a triangle then,
2x+4+2x-9+x=180degree
or, 5x-5=180degree
or, 5x=(180+5)degree
or, 5x= 185degree
or, x=185÷5 = 37degree ans.
PartB
now put the value of x in angle A
i.e angle A = 2x-9
or, angle A= (2×37) - 9
or, angle A= 74 - 9
therefore, angle A= 65degree ans.

Answer:
A+6+A = 20
A = 7
Step-by-step explanation:
J = number of problems Juana completed
A = number of problems Andy completed
J+A=20
J = A + 6
Replace J with A+6 in the first equation
A+6+A = 20
2A +6 = 20
Subtract 6 from each side
2A +6-6 = 20-6
2A =14
Divide by 2
2A/2 = 14/2
A = 7
Answer:
7
Step-by-step explanation:
set up your two equations.
j + a = 20. equation 1
j = a + 6. equation 2
since you know that j = a + 6, you can substitute a + 6 into the place of j. this is because you want to isolate a in order to find out how many problems andy completed.
j + a = 20
a + 6 + a = 20
now solve.
2a + 6 = 20
2a = 14
a = 7
andy has completed 7 problems. if juana completed 6 more than andy, then she has completed 13. 13 + 7 = 20.
six times the quantity two x plus three y
Answer:
12x + 18y
Lets first write the quantity "two x plus three y", this means, that we have x and y as unknowns. x is 2 times, so we have 2x; and y is 3 times, so he have 3y:
2x + 3y
Additionally we have that this quantity is six times, what means that it is multiplied by a number 6:
6(2x +3y)
If you like, we can apply the distributive property that means that given any three numbers a, b, c we have that a(b+c)=ab + ac. In our case a is 6, b is 2x and c is 3y. Thus, operating:
6(2x +3y) = 6*2x + 6*3y = 12x + 18y
So, "six times the quantity two x plus three y" is 12x + 18y
Step-by-step explanation:
Answer:
6(2x+3y)

Zahn takes a summer job selling ice cream bars at the pool. He receives a fixed salary and then additionally a commission for each ice cream bar he sells. The table shows Max's total earnings, y, in dollars, from selling x ice cream bars:
Ice Cream Sales and Earnings
Number of Bars Sold (x)
Total Earnings (dollars) (y)
0
30
1
34
2
38
3
42
Select the equation that best represents the relationship between x and y. (5 points)
a
y = x + 34
b
y = 4x + 30
c
y = 4x + 42
d
y = x + 42
Answer: B
If you look at the table, you notice that he earns 30 without selling ice cream bars. This is his fixed salary.
When he sells one ice cream bar, he earns 34, which means he gets 4 dollars for each bar he sells.
The equation that best represents the relationship between x and y is b) y = 4x + 30, because 4 dollars × number of ice cream bars + fixed salary equals his total earnings.
