A straight line passing through the point (-2,1) and having a gradient of -3 yields the equation y = -3x - 5.
We know that a straight line is an infinitely long line with no curves on it. A straight line's equation is
y = mx + c...(1), where m is the gradient of the straight line and c is a constant.
Given that the gradient of the given straight line = m = -3.
Putting this value in (1), we get
y = -3x + c ...(2)
Again, the given straight line passes through the point (-2,1). So, we can put x = -2 and y = 1 to get the value of the constant c.
So, 1 = (-3)(-2) + c
i.e. 6 + c = 1
i.e. c = 1 - 6 = -5
(2) can be written as
y = -3x - 5
Therefore the equation of the given straight line is
y = -3x - 5

In this course, we have studied two types of geometry: Euclidean and analytical.
In Euclidean geometry, we’ve explored the relationships between points, lines, and planes without any numerical measurement.
In analytical geometry, we’ve explored the relationship between algebra and geometry using positions of points in a Cartesian coordinate system.
Which approach to geometry do you prefer and why? What are some situations in which one approach to geometry would be more beneficial than the other?
The analytical approach is preferable because the primary issue with Euclidean geometry is that it is not enough to support all of the theorems that he claims to establish.
What is geometry?It is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

if f(x) = 4x - 3 and g(x) = x + 4, find (f - g)(x)
Answer:
3x - 7
Step-by-step explanation:
This questions asks about the subtraction of functions. To find the answer, we can subtract the same way we would subtract polynomials.
Subtracting Expressions
First, set up the subtraction problem by taking the expression for f(x) and subtracting the expression equal to g(x) from it.
This looks like:
(4x - 3) - (x + 4)Next, distribute the negative to the second binomial
4x - 3 - x - 4Then, combine like terms
3x - 7Since we are not given a x-value, this is the final answer.
Solving for an X-Value
If you are given an x-value, the best way to solve the equation is to first solve each function and then subtract.
For example, using the same rules for each function let's solve (f-g)(2).
First, solve for f(2) and g(2)
f(2) = 5g(2) = 6Then, subtract the 2 values

What is a common multiple?A Common multiples are known to be the multiples that are said to be common to two or that have more numbers in them.
The Least Common Multiple ( LCM ) is known to be a term that connote the Lowest Common Multiple ( LCM ) and also that has the Least Common Divisor ( LCD).
From the image shown the lowest multiples are 5², 2⁶, 3 while the greatest common factor is 2⁶.
Option B is correct because the greatest common factor which is 2⁶ can only be found in the middle and this was gotten when you add:
2³ . 2³
Collect like terms
2 ³⁺³
2⁶
Therefore, the greatest common factor which is 2⁶
To get the Least Common Multiple, one need to add all the factors in the Venn diagram which are therefore:

The USD appreciates 2% versus the JPY. The USD appreciates 4% versus the MXN. What is the approximate appreciation or depreciation we might see in the JPY/MXN cross exchange rate? Fill in the blanks: The JPY/MXN cross rate should ______________ about ______________ percent
The approximate appreciation or depreciation we might see in the MXN/JPY cross exchange rate is 3%.
What is Depriciation?
The term depreciation refers to an accounting method used to allocate the cost of a tangible or physical asset over its useful life. Depreciation represents how much of an asset's value has been used.
The approximate appreciation or depreciation we might see in the MXN/JPY cross exchange rate can be stated using the following 3 steps.
Step 1. State the initial exchange rates of the currency pairs.
Let first assume the initial exchange rates are as follows:
USD1 = JPY1
USD1 = MXN1
Therefore, we have the initial cross rate as follows:
MXN1 = USD1 = JPY1
MXN1 = JPY1
Step 2. Determine the new exchange rates
The new exchange rates can be determined as follows:
When the USD depreciates 2% versus the JPY, this implies that
USD1 X (100% + 2%) = USD1.02
has to be exchanged for JPY1.
Therefore, we now have:
USD1.02 = JPY1, or
USD1 = JPY1/1.02
USD1 = JPY0.98
Also, when The USD appreciates 1% versus the MXN, this implies that USD1 X (100% - 1%) = USD0.99
has to be exchanged for MXN1.
Therefore, we now have:
USD0.99 = MXN1, or
USD1 = MXN1/0.99
USD1 = MXN1.01
Therefore, we have the new cross rate as follows:
MXN1.01 = USD1 = JPY0.98
MXN1.01 = JPY0.98
MXN1.01 / 1.01 = JPY0.98/1.01
MXN1 = JPY0.97, or
MXN1/0.97 = JPY0.97/0.97
MXN1.03 = JPY1
Therefore, the new exchange rates are as follows:
USD1.02 = JPY1
USD0.99 = MXN1
MXN1.03 = JPY1
c. Determination of appreciation or depreciation we might see in the MXN/JPY
Percentage of depreciation of MXN against JPY = ((Initial MXN/JPY - New MXN/JPY) / Initial MXN/YPY) X 100 = ((1.03 - 1) / 1) * 100 = 3%
Since the percentage of depreciation of MXN against JPY is 3%, this also implies that the percentage of appreciation of JPY against MXN is 3%.
Thus, the approximate appreciation or depreciation we might see in the MXN/JPY cross exchange rate is 3%.

The graph of f(x) = x2 is translated to form g(x) = (x – 5)2 + 1. On a coordinate plane, a parabola, labeled f of x, opens up. It goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). Which graph represents g(x)? On a coordinate plane, a parabola opens up. It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10). On a coordinate plane, a parabola opens up. It goes through (2, 8), has a vertex at (5, negative 11), and goes through (8, 8). On a coordinate plane, a parabola opens up. It goes through (negative 8, 10), has a vertex at (negative 5, 1), and goes through (negative 2, 10). On a coordinate plane, a parabola opens up. It goes through (negative 8, 8), has a vertex at (negative 5, negative 11), and goes through (negative 2, 8).
The transformation of a function may involve any change. When the graph of f(x) is transformed into 5 units to the right and one unit up, then the function g(x) is obtained.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)Vertical shift
Up by d units: y = f(x) + dDown by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: y = k \times f(x)Horizontal stretch by a factor k: y = f(x/k)Given the function f(x)=x², which is transformed to g(x)=(x-5)²+1, therefore, the graph of both the functions are given below.
