Step-by-step explanation:
What is substitution method?
The substitution method is where you plug in an expression that defines a variable into the other equation so you are left with one variable in which you can solve for.
In order to use the substitution method, one of the variables must be defined by an expression (e.g. x = 8y + 2 , the x is defined by the expression 8y + 2. )
Rearranging terms to define x or y
We have the two equations 2x + y = 15 and 7x - 2y = -8
The equation we would rearrange would likely be 2x + y = 15 as the y is by itself meaning we could easily change a few things to define it.
2x + y = 15
==> subtract 2x from both sides
2x - 2x + y = 15 - 2x
==> simplify
y = 15 - 2x
Plugging ( or substituting ) y's defined expression into the other equation.
Now that we have rearranged the equation to where "y" is being defined we can plug in the expression defined by y into the other equation and then solve for x.
2nd equation : 7x - 2y = -8
==> plug in y = 15 - 2x
7x - 2(15-2x) = -8
==> distribute the 2
7x - 30 + 4x = -8
==> combine like terms
11x - 30 = -8
==> add 30 to both sides
11x = 22
==> divide both sides by 11
x = 2
Substituing the value of x into one of the equations and then solving for y.
Now that we have calculated the value of x we can calculate the value of y by plugging in the value of x into one of the equations and solving for y.
2x + y = 15
==> plug in x = 2
2(2) + y = 15
==> multiply 2 and 2
4 + y = 15
==> subtract 4 from both sides
y = 11
The solution is (2,11)
Checking our work:
To check our work we can plug in the value of x and y into both equations. If both are true then the solution is correct but if one or both are false then the solution is incorrect.
First equation; 2x + y = 15
==> plug in x = 2 and y = 11
2(2) + 11 = 15
==> multiply 2 and 2
4 + 11 = 15
==> add 4 and 11
15 = 15
Second equation; 7x - 2y = -8
==> plug in x = 2 and y = 11
7(2) - 2(11) = -8
==> multiply 7 by 2 and 11 by -2
14 - 22 = -8
==> subtract 22 from 14
-8 = -8
Both are correct therefore (2,11) is the correct solution
A high speed train travels a distance of 503 km in 3 hours.
The distance is measured correct to the nearest kilometre.
The time is measured correct to the nearest minute.
By considering bounds, work out the average speed, in km/minute, of the train to a suitable degree of accuracy.
You must show your working.
To gain full marks you need to give a one-sentence reason for your final answer the words 'both' and 'round' should be in your sentence.
The average speed, in km/minute, of the train is 2.79 km/minute
Calculating average speedFrom the question, we are to calculate the average speed in km/minute
From the given information,
Distance travelled = 503 km
Time taken = 3 hours = 3 × 60 minutes = 180 minutes
Using the average speed formula,
Average speed = Distance / Time
∴ Average speed of the train = 503 / 180
Average speed of the train = 2.79 km/minute
Hence, the average speed, in km/minute, of the train is 2.79 km/minute

The preimage undergoes the sequence of transformations to produce an image, figure 1.
1. reflection across a horizontal line
2. rotation counterclockwise about point P
3. dilation with a scale factor of 1
Based on the transformations that occurred, the preimage is most likely the topmost right image.
Where is the preimage?The transformations list shows that the first transformation was the reflection across the horizontal line drawn.
When a reflection is done, the shape looks like the inverse of itself. The only shape that looks like an inverse and is therefore a reflection is the bottom right shape which means the preimage must be the top right image.

The domain and range of the given function are equal to (0, 3.85) and (0, 18.75) respectively.
How to calculate the domain of the function?In this exercise, you're given the following function h(t) = -4.87t² + 18.75t. Next, we would equate the function to zero (0) to determine its domain as follows:
0= -4.87t² + 18.75t.
4.87t(-t + 3.85) = 0
t = 0 or t = 3.85.
Therefore, the domain is 0 ≤ t ≤ 3.85 or (0, 3.85).
How to calculate the range of the function?h(t) = -4.87t² + 18.75t
h(t) = -4.87(t² - 3.85t + 3.85 - 3.85)
h(t) = -4.87(t - 1.925)² + 18.05
Therefore, the range is 0 ≤ h ≤ 18.05 or (0, 18.75).

Answer:
A on EDGE 2022
Step-by-step explanation:
Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points)
Part B: Make tables to find the solution to 4x = 2x−2. Take the integer values of x between −3 and 3. (4 points)
Part C: How can you solve the equation 4x = 2x−2 graphically? (2 points)
(10 points)
Answer:
Step-by-step explanation:
A: The expression 4x = 2x - 2 reduces to x = -1. This is true for all values of y, since y is not a factor in this expression.
The two other equations intersect at point (-1, -4). See the attached graph (Solutions2)
y = 4x
y = 2x−2
============
Mathematically, we can substitute the value of y from the first equation into the second:
y = 2x−2
(4x) = 2x−2
2x = -2
x = -1
The intersection of this two lines is (-1,-4). Since x=-1, this is also the solution to 4x=2x-2, as per the above.
B: See attached Result Table
C: See GraphEquation2

Answer:
Rain shower is most likely to occur where Richard is. (Option c)
• The air pressure is lower than the normal and that's why it suggests that the rainfall will happen in that place because rainfall generally occurs in the place where the low pressure is formed.
• And,the temperature is above than the freezing point of the water so there are no chances of the snowfall in that place.
• That's why rainfall is the most probable thing that will happen in that place.
