Is (2, 4) a solution of the equation y = x - 2 ?
Answers
Answer: No, (2,4) is not a solution to the equation y = x-2
===============================================
Explanation:
We can show this by plugging x = 2 into the equation. We should get y = 4 if (2,4) was a solution
y = x-2
y = 2-2 ... replace x with 2
y = 0
Since we didn't get y = 4, this means (2,4) is not a solution
-----------------
A similar method would be to do these steps
y = x-2
4 = 2-2 ... replace x with 2, replace y with 4
4 = 0 ... false equation
The false equation shows y = x-2 is not true when (x,y) = (2,4)
-----------------
The graph of y = x-2 does not have the point (x,y) = (2,4) on the line.
So this is a visual way to confirm (2,4) is not a solution to y = x-2.
See the graph below.
(2, 4) is not a solution to the equation y = x - 2.
Given,
(2, 4)
We need to see whether (2, 4) is a solution to the equation y = x - 2.
What is a solution to an equation?The solutions are the values that satisfy the equation.
Example: y = x + 1
(1, 2) is a solution to y = x + 1.
( 1, 2 ) = ( x, y )
2 = 1 + 1
2 = 2
We have,
(2, 4) = (x, y)
y = x - 2
Put x = 2 and y = 4
4 = 2 - 2
4 = 0
Which is not true.
Thus (2, 4) is not a solution to the equation y = x - 2.

Answer:
Step-by-step explanation:
The meaning of the solution x < - 10 or x ≥ 25 is the solution is in the interval (- ∞,- 10) ∪ [25, ∞).
What is an interval?An interval is a collection of real numbers that lie between two given values known as the interval's endpoints.
We are aware that two sets' components were combined to create the set. The set of elements in A, B, or both is the result of adding sets A and B together. It's indicated by '∪'.
How to solve?For x < - 10 , the solution is in the interval (- ∞,- 10).
For x ≥ 25, the solution is in the interval [25, ∞).
For x < - 10 or x ≥ 25, we can say that the solution is in the interval
(- ∞,- 10) ∪ [25, ∞).
Therefore the meaning of the solution x < - 10 or x ≥ 25 is the solution is in the interval (- ∞,- 10) ∪ [25, ∞).

Answer: A: 180= 90+4x+x
B: x=18
Step-by-step explanation:
1. Every triangle has a length of 180
2. So all the measurements combined would equal 180
3. So write the equation 180=90+4x+x
4. Let‘s simplfy, 180=90+5x
5. Subtract 90 from each side, 90=5x
6. Divide each side by 5, 18=x.

A prospector graphed the locations of a gold vein and all of the
gold dust strikes in the vicinity. She positioned the gold vein at
(-2,9) and the farthest gold dust strike at (94,9). If each unit on the
graph represents 1 mile, then how far away from the gold vein is
the farthest gold dust strike?
Answers
Answer:
The gold vein is 96 miles away from the farthest gold dust strike.
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
The prospector positioned the gold vein at (-2,9) and the farthest gold dust strike at (94,9). We are required to calculate the distance between these two points. Use the formula:
[tex]d=\sqrt{(9-9)^2+(94-(-2))^2}[/tex]
[tex]d=\sqrt{0^2+96^2}[/tex]
[tex]d=\sqrt{96^2}=96[/tex]
The distance is 96 units, but we know each unit on the graph represents 1 mile, thus the gold vein is 96 miles away from the farthest gold dust strike.

The year in which the total personal income will reach 22 trillion dollars is 2033 years.
What year will the total personal income reach 22?The year in which the total personal income will reach 22 trillion dollars is calculated by applying a method known as extrapolation for the data in the table.
At year 1996, total personal income = 8429.2
At year 2001, total personal income = 10,239.5
At year ?, total personal income = 22,000
(? - 2001) / (2001 - 1996) = (22,000 - 10,239.5) / (10,239.5 - 8429.2)
(? - 2001 ) / 5 = 6.496
? - 2001 = 5 x 6.496
? - 2001 = 32.48
? = 2001 + 32.48
? = 2033.48
? ≈ 2033 years
Thus, the year in which the total personal income will reach 22 trillion dollars is 2033 years.

Answer:
A) Each of the smaller donations is $20.
B) The larger donation is greater than the smaller donations by $15.
Step-by-step explanation:
4+4+7 is equal to 15, and divide 75 by 15 to get $5 per part. Multiply 4 by 5 to get $20 for a smaller donation, and 7 by 5 to get $35 for the larger donation. Hope this helped :)
Answer:
Smaller donations each cost $20
The bigger donation is $15 more than the smaller ones.
Step-by-step explanation:
Let 4x be defined as the amount of the smaller donation, and let 7x be defined as the larger amount of the donation. We can then set up an equation:
4x+4x+7x = 75
15x = 75
x = 5
We can now plugin 5 for x to solve for the smaller donation and the larger donation:
Smaller donation = 4*5 = 20
Bigger donation = 7*5 = 35
Now, to find how much greater the bigger donation is, we just subtract 35 from 20, which is 15.

What is an equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.
Now, y=5x-4x
