The x coordinate will be -4 for the expression "a point 4 unit to the left of 0".
We are given an expression:
" a point 4 unit to the left of 0 "
We need to find the value of x coordinate for this expression.
In geometry, a coordinate system is a system that makes use of one or extra numbers, or coordinates, to uniquely decide the placement of the factors or different geometric factors on a manifold which include Euclidean space.
We can write the expression as:
4 unit to the left of 0 will be - 4
So the point becomes:
( - 4 , 0)
So, the x coordinate becomes,
x = - 4
Therefore, the x coordinate will be -4 for the expression "a point 4 unit to the left of 0".

A school is organizing a weekend trip to a nature preserve. For each student, there is a $60 charge, which covers food and lodging. There is also a $40 charge per student for the bus. The school must also pay a $30 cleaning fee for the bus. If the total cost of the weekend is $4,030, how many students will be going on the trip?
31 students
40 students
41 students
66 students
Answer:
40 students
Step-by-step explanation:
I think it is 40 students because 60 + 40= 100 then 100 x 40 = 4,000
then the SCHOOL has to pay a $30 cleaning fee so that will add up to $4,030! I hope this helps everybody!
40 students will be going on the trip
How to calculate the number of students that will be going on the trip ?Each student will pay $60 for food and lodging
Each student will also pay $40 for the bus
Total amount of fee that will be paid by each student is
= 60 +40
= 100
The school will pay $30 cleaning fee for the bus, it's only the school that will be paying this fee, the students are not included. This will will be subtracted from the total cost which is $4,030 leaving us with $4,000
Therefore the number of students going on the trip can be calculated as follows
= 4,000/100
= 40
Hence 40 students will be going on the trip

The original equation will be x + x + 1 = 67 and the left page will have 33 page number and the right one will have 34 page number.
Let x be the first consecutive integer.
So, x + 1 is the first consecutive integer.
Sum of the two integers = 67
⇒ x + x + 1 = 67 (This is the original equation)
Combining the like terms:
⇒ 2x + 1 = 67
Subtract 1 from both the sides:
⇒ 2x = 67 - 1
⇒ 2x = 66
Divide both sides by 2:
⇒ x = 66/2 = 33
Therefore, the original equation will be x + x + 1 = 67 and the left page will have 33 page number and the right one will have 34 page number.

How much greater was the percent of change from Week 1 to Week 2 than from Week 2 to Week 3? Round to the nearest tenth of a percent
Randy's percentage change from Week 1 to Week 2 was 2.37% greater than Week 2 to Week 3.
The percentage change will be calculated by the relation -
Percentage change = change in timing ÷ original time × 100
Calculating percentage change between Week 1 and Week 2
Change = 28.8 - 27.6
Change = 1.2 seconds
Percentage = (1.2 ÷ 28.8) × 100
Percentage = 4.17%
Calculating percentage change between Week 2 and Week 3
Change = 27.6 - 27.1
Change = 0.5 seconds
Percentage = (0.5 ÷ 27.6) × 100
Percentage = 1.8%
So, percent of change from Week 1 to Week 2 than from Week 2 to Week 3 was = 4.17 - 1.8
Percentage change = 2.37%

The nearest decimal which is the approximate value of x is 18°..
The two slanting lines given in the diagram are parallel.
Furthermore, the horizontal line crosses both parallel lines given above.
Then the measure of the angles marked in the question is equal.
Therefore, we have 5x + 7° = 9x - 63°.
⇒ 63° + 7° = 9x - 5x
⇒ 70° = 4x
⇒ x = 70°÷ 4 = 17.5° ≈ 18°(approximate to the nearest decimal)
Therefore, x = 18°
Let us now compute the magnitude of each angle.
5x + 7 = 5 × 18 + 7 = 90 + 7 = 97
9x - 63 = 9 × 18 - 63 = 162 - 63 = 99
The measurement of these two angles differs by two degrees.. Because the value of x is not exact. We used the approximated value.
Let us recalculate the angle measurements using the exact value 17.5.
5x + 7 = 5 × 17.5 + 7 = 87.5 + 7 = 94.5
9x - 63 = 9 × 17.5 - 63 = 157.5 - 63 = 94.5
So, the exact value of x is 17.5°.

|x-2|=|4+x|
How can I find the value of X?
Answer:
x = -1
Step-by-step explanation:
You want to find the value(s) of x that satisfy the equation |x-2| = |4+x|.
DomainsThe behavior of each absolute value function changes at the point where its argument is zero. For this equation, that will be two points:
x -2 = 0 ⇒ x = 2
x +4 = 0 ⇒ x = -4
These two points on the number line divide the domain of the equation into three parts:
x < -4-4 ≤ x < 22 ≤ x.The behavior of the equation will be different in those three domains.
x < -4In this domain, both absolute value functions negate their arguments. That means the equation is equivalent to ...
-(x -2) = -(4 +x)
2 = -4 . . . . . . . . . . add x to both sides
This has no solutions: there are no values of x that will make this true.
-4 ≤ x < 2In this domain, the absolute value function on the left negates its argument, so the equation is equivalent to ...
-(x -2) = (4 +x)
-2 = 2x . . . . . . . . . add x-4 to both sides
-1 = x . . . . . . . . . divide by 2
This value of x is in the domain, so represents a solution to the equation.
x = -1
2 ≤ xIn this domain, neither absolute value function negates its argument, so the equation is equivalent to ...
x -2 = 4 +x
-2 = 4 . . . . . . . subtract x
This has no solutions: there are no values of x that will make this true.
The given equation has one solution: x = -1.
__
Additional comment
When solving an equation like this graphically, it is often useful to put it in the form f(x) = 0. We can obtain that form by defining ...
f(x) = |x -2| -|4 +x|
The graph of this is attached. The only solution is where f(x) = 0, at x = -1.
Note that the function is parallel to the x-axis outside of the middle domain, so will not have any x-intercepts in those regions.
