What kind of relation is a function?It follows from the task content that the relation is to be determined as being a function or not.
Since the definition of is such that; a function from a set X to a set Y assigns only one element of Y to each value of X.
In this regard, the set of possible values of x is called the domain of the function while the set y is called the range/codomain of the function.

The equation of the line passing through points (-2, 1) and (1, -4) is f(x) = (-5/4)x - 3/2
In this question we have been given two points.
We need to find an equation of the line passing through points (-2, 1) and (1, -4)
Using the two-point form of equation of line.
(y - y1)/(y2 - y1) = (x - x1) / (x2 - x1)
(y - 1) / (-4 - 1) = (x - (-2)) / (1 - (-2))
(y - 1) / (-5) = (x + 2) / (1 + 3)
y - 1 / (-5) = (x + 2) / 4
y - 1 = (-5/4)(x + 2)
y = -5x/4 - 10/4 + 1
y = (-5/4)x - 3/2
Let y = f(x)
so, equation of line is f(x) = (-5/4)x - 3/2
Therefore, the equation of line passing through points (-2, 1) and (1, -4) is f(x) = (-5/4)x - 3/2

[tex]\begin{gathered} y=tan(3x+3) \\ dy=3sec^2(3x+3)dx \end{gathered}[/tex]To find the differential dy when x = 5 and dx = 0.4, simply replace the x and dx in the dy function with their given values.

Lena worked for 5 hours if she prepared 10.75 kilograms of dough assuming 4.3 directly proportional 2.
What is proportional?A comparison of two numbers mathematically is called a proportion. Two sets of given numbers are said to be directly proportional to one another if they increase or decrease in the same ratio, according to the law of proportion. The symbols "::" or "=" are used to indicate proportions.
We have given that 4.3 ∝ 2
where 4.3 kilograms is completed in 2 hours
If 4.3 ∝ 2, the constant k is
4.3 = k2
k = 4.3/2
k = 2.15
We have asked to find how many hours did Lena work if she prepared 10.75 kilograms of dough.
Let hours she took be x, Thus
10.75 ∝ x
We already have the contestant, so this gives us
10.75 = kx
10.75 = 2.15x
x = 10.75/2.15

Figure W was ___ to create W’. Figure W’ was dia lates by a scale factor of ___ fromThe origin to create w”
Transformations
One of the rigid transformations is reflection. When a figure is reflected across some line, it maps to the very same shape but inverted as if the line was a mirror.
Right between figures W and W' the y-axis separates two identical images as if the y-axis was a mirror, thus:
Figure W was reflected over the y-axis to create figure W'
A Dilation from the origin maps an object to another such that its vertices are all multiplied by a common factor (scale factor).
For example, the upper-right vertex of W' is located at (2-2). The upper-right vertex of W'' is at (4,-4). The scale factor is 2.
The bottom-left vertex of W' is at (4,-4) and the bottom-left vertex of W'' is at (8,-8). We find the same scale factor of 2. If we tested all of the vertices, we'll obtain the same scale factor of 2, thus:
Figure W' was dilated by a scale factor of 2 from the origin to create figure W''

When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the name of this constant.The equation y = 2.5x is a proportional relationship because y increases by a certain amount when x increases. That amount is shown by the slope of the line which is 2.5.

Greg graduated in the bottom 9% of his class. If the mean was 585 and the standard deviation was 134, and the distribution was normal, what was Greg's raw score?
Greg's raw score in the test is 405
How to determine the raw score of the test?The given parameters are
Mean = 585Standard deviation = 134Proportion, p = bottom 9%The above implies that
z = P(p < 0.09)
From z tables of probabilities, we have
z = -1.34
The z-score of the data value is calculated using the following formula
z = (raw score - mean value)/standard deviation
Substitute the given parameters in the above equation
-1.34 = (raw score - 585)/134
This gives
-180 = raw score - 585
So, we have
raw score = 585 - 180

If the social security tax to be paid is 1.5 percent of one's income, and Jadiel earned $23,400 this year, then he has to pay $351 as his social security tax.
As per the question statement, the social security tax to be paid is 1.5 percent of one's income, and Jadiel earned $23,400 this year working part time.
We are required to calculate the amount Jadiel has to pay from his income as his social security tax.
To solve this question, we simply need to calculate 1.5% of Jadiel's annual income to obtain our desired answer, that is,
1.5% of $23400 = $[(1.5/100) * 23400] = $(1.5 * 234) = $351.
Hence, Jadiel has to pay $351 as his social security tax for this year.

Martha has 31 1/4 ft of tape to be used for taping up boxes
Each box needs 12 1/2 ft of tape
To find how many boxes Martha can tape up, we need to divide 31 1/4 by 12 1/2
First, we need to convert these mixed numbers into fractions, as follows:
[tex]\begin{gathered} 31\frac{1}{4}=\frac{31\cdot4+1}{4}=\frac{125}{4} \\ 12\frac{1}{2}=\frac{12\cdot2+1}{2}=\frac{25}{2} \end{gathered}[/tex]Dividing by a fraction is the same as multiplying by its inverse, then:
[tex]\frac{31\frac{1}{4}}{21\frac{1}{2}}=\frac{\frac{125}{4}}{\frac{25}{2}}=\frac{125}{4}\cdot\frac{2}{25}=\frac{5}{2}=2\frac{1}{2}[/tex]Given that you can't tape up 2 1/2 boxes, Martha can only tape up 2 boxes. To tape up 2 boxes she needs the next amount of tape:
[tex]12\frac{1}{2}\cdot2=\frac{25}{2}\cdot2=25\text{ ft of tape}[/tex]The leftover is computed as follows:

How much did he have to mortgage?
Using mathematical operations we conclude that Greg has to mortgage the amount of $66,000.
What are mathematical operations?An operation, also known as an "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the operations that are most frequently studied. The addition, subtraction, multiplication, division, exponentiation, and modulus operations are carried out by the arithmetic operators.So, the mortgage will be:
$92,500 - $26,500Solve this expression as follows:
