Considering the definition of an inequality and system of inequalities, the correct option is: "No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100."
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
System of inequalitiesA system of inequalities is made up of two or more inequalities.
The solution will be formed by the intersection of the half-planes of each of the inequalities, that is, it will be the enclosure that all the inequalities have in common. That is, the solution of the system is given by the region of the common plane of the half-planes that define each one of the inequalities.
System of inequality in this caseIn this case:
c represents child bikes.a represents adult bikes.Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. The company is able to have up to 120 hours of building time and 100 hours of testing time for a week.Then, the system of inequality is:
[tex]\left \{ {{4c+6a\leq 120} \atop {4c+4a\leq 100}} \right.[/tex]
On the other hand, the company can build 20 child bikes and 6 adult bikes in the week. So, checking the equations, for given c=20 and a=6:
4×20 + 6×6= 116 < 120
4×20 + 4×6= 104 >100
Finally, the correct option is: "No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100."

system:
[tex](3,-2)[/tex]
Answer:
(3, - 2 )
Step-by-step explanation:
- 3x - 7y = 5 → (1)
15x + 6y = 33 → (2)
multiplying (1) by 5 and adding to (2) will eliminate x
- 15x - 35y = 25 → (3)
add (2) and (3) term by term to eliminate x
0 - 29y = 58
- 29y = 58 ( divide both sides by - 29 )
y = - 2
substitute y = - 2 into either of the 2 equations and solve for x
substituting into (2)
15x + 6(- 2) = 33
15x - 12 = 33 ( add 12 to both sides )
15x = 45 ( divide both sides by 15 )
x = 3
solution is (3, - 2 )

How is the relationship between the length and area of the rectangle different from other kinds of relationships we've seen before ?
The area of a rectangle = Length × Breadth
The area of a rectangle is the product of the breadth and length of a rectangle. A = L * W, where A is the area, L is the length, W is the width or breadth.We must determine the product of a rectangle's length and breadth in order to get its area.Area of a rectangle is equal to length times width.For instance, if a rectangle has a length of 50 cm and a width of 7 cm, its area is equal to 350 square cm (50 × 7 square cm).Every angle of a rectangle measures 90°.

What is the approximate total length of iron edging needed to create the square frame and the two diagonals? 43.5 inches 50.9 inches 54.0 inches 61.5 inches
Total length of iron edging needed to create the square frame is 43.5 inches
Important properties of square:
All four interior angles are equal to 90°
All four sides of the square are congruent or equal to each other.
The opposite sides of the square are parallel to each other.
The diagonals of the square bisect each other at 90°
The two diagonals of the square are equal to each other.
Diagonal of square = [tex]\sqrt{2}[/tex]a
9 = [tex]\sqrt{2}[/tex]a
a = [tex]\frac{9}{\sqrt{2}}[/tex]
a = 6.36 inches
Iron edging needed to create the square frame = 4*6.36 = 25.44 inches
iron edging needed to create two diagonals = 2*9 = 18 inches

32.For the following exercises, given each set of information, find a linear equation satisfying the conditions, if possible.
32. (2, 4) and (4, 10)
Answer:
The required linear equation satisfying the given points (2,4) and (4,10) is y=3x-2
Step-by-step explanation:
Two points are given in question, (2,4) and (4,10).
It is required to find out a linear equation satisfying the points (2,4) and (4,10).
To find it out, find the slope of a line passing through these two given points. Then consider one of the points to give the linear equation of the line in the
[tex]$$\left(y-y_{2}\right)=m\left(x-x_{2}\right)$$[/tex]
Step 1 of 3
The slope of a line passing through the points (2,4) and (4,10) is given by
[tex]$$\begin{aligned}m &=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\m &=\frac{10-4}{4-2} \\m &=\frac{6}{2} \\m &=3\end{aligned}$$[/tex]
Step 2 of 3
Now use the slope m=3 and use one of the two given points and write the equation in point-slope form:
[tex]$$\left(y-y_{2}\right)=m\left(x-x_{2}\right)$$\\ $$(y-4)=3(x-2)$$[/tex]
Distribute 3 ,
[tex]$$\begin{aligned}&y-4=3 x-3 \times 2 \\&y-4=3 x-6\end{aligned}$$[/tex]
Step 3 of 3
This linear function can be written in the slope-intercept form by adding 4 on both sides,
[tex]$$\begin{aligned}&y-4+4=3 x-6+4 \\&y=3 x-2\end{aligned}$$[/tex]
So, this is the required linear equation.

The statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
0.1x + 0.25y = 19.9 and
x + y = 100
Let x = number of dimes
y = number of quarters
After solving the above system of equations by substitution method.
[tex]\rm \dfrac{398-5y}{2}+y=100[/tex]
y = 66
[tex]\rm x=\dfrac{398-5\cdot \:66}{2}[/tex]

A rectangular tank has its width exactly half its length. That the height of the tank is 3M and the length is 8m. What is the volume of the tank in M3?
Answer:
Volume = 96m^3
Step-by-step explanation:
If the length of the tank is 8 meters, then the width must be 4 meters, because the question said the width was half the length. Since the height, 3 meters, was also given, we can find the volume.
Vol = L × w × h
We multiply together the length, width and height.
Vol = 8 × 4 × 3

The sum of two numbers is 79. Three times the first number added to 5 times the second number is 283. What are the two numbers?
Answer:
The two numbers are 56 and 23.
Step-by-step explanation:
Let the two numbers be A and B.
We are told that:
A+B = 79, and
2) 3A + 5B = 283
Rearrange the first expression to isolate A:
A = 79-B
Now use this value of B in the second expression:
3A + 5B = 283
3(79-B) + 5B = 283
237-3B + 5B = 283
2B = 46
B = 23
If B=23, we can find A from (1):
A+B = 79
A+23 = 79
A = 56
CHECK:
Does A+B = 79?
56 + 23 = 79? YES
Does 3A + 5B = 283?
3(56) + 5(23) = 283?

if (x + q) is a factor of two polynomials x2 + px + q and x2 + mx + n, then prove that a = n-q m-p
Answer:
factor polynomial is x+q so x=-q
putting the value of x in both equations
eqn 1)a^2+p(-a)+q=0
a^2 -ap+q=0
eqn 2)a^2+m(-a)+n=0
a^2-am+n=0
Since both are equal to zero,we can write:
a^2-ap+q=a^2-am+n
-ap+am=n-q
a(-p+m)=n-q
a=(n-q)/(m-p)
Explanation:
Since (x + a) is a factor of the two polynomials, when x = -a, the polynomials should both equal 0 (this is known as the factor theorem).
• First equation:
[tex]x^{2} + px + q[/tex]
When x = -a:
[tex](-a)^{2} + p(-a) + q = 0\\\\a^{2} -pa + q = 0[/tex]
• Second equation:
[tex]x^{2} + mx + n[/tex]
When x = -a:
[tex](-a)^{2} + m(-a) + n = 0\\\\a^{2} -ma + n = 0[/tex]
• As both equations equal 0, we can equate them:
[tex]a^{2} -pa + q = a^{2} -ma + n \\\\-pa + ma = n - q\\\\a(m - p) =n -q\\\\a = (n - q)/ (m - n)[/tex][proven]
