define the concept function and give conditions which make relation a function?
Answer:
A function is a relation which describes that there should be only one output for each input (or) we can say that a special kind of relation (a set of ordered pairs), which follows a rule i.e., every X-value should be associated with only one y-value is called a function.
Step-by-step explanation:
x + 7y = 21
x + 4y = 15
Solve the simultaneous equations
Answer:
x = 7, y = 2
Explanation:
equations given:
x + 7y = 21
x + 4y = 15
make "x" the subject:
x + 7y = 21
x = 21 - 7y .........equation 1
x + 4y = 15
x = 15 - 4y .......equation 2
Solving both the equations simultaneously:
15 - 4y = 21 - 7y
-4y + 7y = 21 - 15
3y = 6
y = 6 ÷ 3
y = 2
If y is 2
Then x = 21 -7y;
x = 21 - 7(2)
x = 21 - 14
x = 7
x + 7y= 21
7 goes to RHS = X+ y = 21/7-3
x + 4y = 15
4 goes to RHS= x+y = 15/4 = 3.75

Given :-
A linear equation in two variables , 3x + 6y = 24 .To Find :-
The x and y intercept of the graph .Solution :-
Given equation is ,
[tex] 3x + 6y = 24 [/tex]
To find the y intercept set x = 0 , we have ,
[tex] 3(0) +6y = 24 [/tex]
Simplify ,
[tex] 6y = 24[/tex]
Divide both sides by 6 ,
[tex] y = 4 [/tex]
Hence the y intercept is 4 .

Would adding these matrices give a meaningful result in this situation? Why or Why not?
Would subtracting these matrices give a meaningful result in this situation? Why or Why not?
Yes, adding the matrices would give a meaningful result as it provides a measure of the total number of nutrient and calorie intake throughout the day.
Yes, subtracting the matrix from each other gives a measure of the surplus or deficit of nutrients and calorie intake between any pair of meals.
Matrix addition and SubtractionA matrix can only be added to (or subtracted from) another matrix if the two matrices are of the same dimensions .
Hence, it follows that to add or subtract two matrices, just add or subtract the corresponding entries, and place this sum or difference in the corresponding position in the matrix which results accordingly.

Find the domain and range of the following relation also determine whether the relation is a function.
Domain:-
Venus,Mars, Jupiter,Saturn, Neptune,PlutoRange:-
18,29,31,27Yes it's a function as domains have unique range
Answer:
Domain = Planet
Range = number of solar congress reps
Function = YES (many-to-one)
Step-by-step explanation:
Domain : input values ⇒ planet
Range : output value ⇒ number of solar congress reps
Function : A function relates each element of a set with exactly one element of another set (possibly the same set).
One-to-many is not a function.
Many-to-one is a function.
From inspection, we can see that every element in the domain is related to exactly one element in the range. Both Venus and Neptune are related to 18. So this is a many-to-one function.
The figure above shows that the shaded triangular region with a hypotenuse of 5 cm has been removed from a rectangular tile with dimensions x cm by y cm. Of the following which best approximates the area in square cm of the tile before the piece was removed
Check the picture below.
Mind you that we have four 30-60-90 triangles.
The area of given rectangle before the piece was removed is 65 cm² approximately.
What is area of rectangle?The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'. So, Area of Rectangle = (a × b) square units.
In Δ DEF,
∠EDF + ∠DEF + ∠DFE = 180° (angle sum property)
30° + 90° + ∠DFE = 180°
∠DFE = 60°
[tex]cos F = \frac{EF}{FD}(\frac{base}{hypotenuse}\\ \\ cos(60) = \frac{5}{FD}\\ \\FD = 5 * 2= 10[/tex]

In Δ AED,
∠AED + ∠EAD + ∠EDA = 180° ( angle sum property)
∠AED + 90° + 30°= 180°
∠AED = 60°
[tex]sinE = \frac{AD}{DE} (\frac{perpendicular}{hypotenuse}\\ \\sin(60) = \frac{AD}{5\sqrt{3} } \\\\AD= \frac{\sqrt{3} }{2}*5\sqrt{3} \\\\AD = 7.5[/tex]
In Δ DFC,
∠FDC + ∠DCF + ∠DFC = 180° (angle sum property)
30° + 90° + ∠DFC = 180°
∠DFC = 60°
[tex]sinF = \frac{DC}{DF} \\\\sin(60) = \frac{DC}{10}\\ \\\frac{\sqrt{3} }{2} *10 = DC\\\\DC = 5\sqrt{3}[/tex]
Area of rectangle = length * breadth = xy = AD * DC = [tex]7.5 * 5\sqrt{3} = 64.95[/tex]
