Which inequality has no solution? 6 (x 2) greater-than x minus 3 3 4 x less-than-or-equal-to 2 (1 2x) negative 2 (x 6) less-than x minus 20 x minus 9 less-than 3 (x minus 3)
From the provided equations, the equation which has no solution is 3 4 x less-than-or-equal-to 2 +4x. Option 2 is correct.
What is the inequality equation?Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
From the given equations, the equation which has no solution has to be found out. When the value, does not equate for the expression, then the expression has no solution.
The first equation given in the problem is,
[tex]6 (x +2) > x-3[/tex]
Solve it further,
[tex]6 x +12 > x-3\\6x-x > -3-12\\5x > -15\\x > -3[/tex]
The second equation given in the problem is,
[tex]3+ 4x \leq 2 (1 +2x)[/tex]
Solve it further,
[tex]3+ 4x \leq 2 +4x\\4x- 4x \leq 2-3\\0\leq-1[/tex]
The value of 0 is greater than the number -1. Thus, this inequality has no solution.
The option 3 and 4 has a solution. Hence, from the provided equations, the equation which has no solution is 3 4 x less-than-or-equal-to 2 +4x. Option 2 is correct.

Name if even, odd or neither
x4 + x²
see attached graph and I only want help with number 1. I want to learn so I can do the rest on my own.
Answer:
Examine each term of the polynomial to determine whether it is even, odd, or neither.
Even = each term is an even functionOdd = each term is an odd functionNeither = terms are even and odd termsEven function → symmetry about the y-axis
Odd function → symmetry about the origin
1) y = x⁴ is an even function, as it has symmetry about the y-axis
y = x² is an even function, as it has symmetry about the y-axis
Therefore, x⁴ + x² is an even polynomial
2) [tex]\sf y=6x^5[/tex] is an odd function, as it has symmetry about the origin.
[tex]\sf y=-x^3[/tex] is an odd function, as it has symmetry about the origin.
Therefore, [tex]\sf y=6x^5-x^3[/tex] is an odd polynomial
**Please see attachments for examples of even and odd functions**
Note:-
Every power of function variables are responsible for even odd like powe is odd function is odd power is even function is even
#1
x⁴+x²4 and 2 are even
Symmetry about y axisEven

Answer:
1. 2n + 10
2. 12x + 60 - 36y
3. -a + 4 - 6b
Step-by-step explanation:
1) Distribute the 2.
2(n) + 2(5)
= 2n + 10
2) Distribute the 12.
12(x) + 12(5) + 12(-3y)
= 12x + 60 - 36y
3) Distribute the negative sign.
note: a single negative sign is the same as -1
a(-1) + -4(-1) + 6b(-1)
= -a + 4 - 6b

If Clovis has spent a total of 123.35 for airline ticket and taxi ,the percent of fare that He tip the taxi driver is At 20%.
What is percentage?A percentage serves as a number or ratio which is been expressed as a fraction of 100.
The amount paid for the airline Ticket and the Taxi is 123.35
Sales Tax on the airline Ticket is 15% of $69, which can be calculated as [tex](15/100 * 69)=10.35[/tex]
The amount without any tip can be calculated as[tex][10.35 +20+69+(2.5*8)][/tex]
To get the amount with the tip, we will substract the from the total amount of airline ticket 123.35 from amount for the tip which is
(123.35-119.35)= 4.
Then we can calculate percentage of the tip as

The answer is C
- airline ticket: $69
- sales tax, 15%: $10.35
- baggage fee: $20.
- taxi: 8 miles * $2.50 per mile = $20
Sub-total: 69 +10.35 + 20 + 20 = $ 119.35
If Clovis has spent a total of $123.35 => tip = 123.35 - 119.35 = $4.00
at what percent of his fare did Clovis tip the taxi driver?
[$4 / $20] * 100 = 20%

Raising livestock is a no easy task. However, Tony believes that investing in this kind of business would be smart. He wanted to start by raising goats. He decided to make an enclosure by erecting a fence around the rectangular piece of land that he owns. Suppose that the land has
an area of 192 m2 and the length is 4m longer than the width. What is the perimeter of the land
that he will fence?
The perimeter of the land that Tony will fence around the rectangular piece of land that he owns is 56 meters.
What is the perimeter of a rectangle?
The measure of the boundary of the sides of a rectangles called its perimeter. The perimeter of a rectangle is twice the sum its length and width.
[tex]P=2(l+w)[/tex]
Here, (l) is the length of the rectangle and (w) is the width of the rectangle.
The land has an area of 192 m2 and the length is 4m longer than the width. Let suppose the length is l. Thus,
[tex]l=4+w[/tex]
Now the area of rectangle is the product of length and width. Thus,
[tex]A=l\times w\\192=(4+w)\times w\\192=4w+w^2\\w^2+4w-192=0\\w^2+16w-12w-192=0\\w(w+16)-12(w+16)=0\\(w+16)(w-12)=0\\w=-16,12[/tex]
Taking positive side, w=12. The width of the rectangle is 12 m. The length of the rectangle is 4 m longer than the width. Thus, the length of it si 16 m (12+4). Its, perimeter is,
[tex]P=2(16+12)\\P=56\rm\;m[/tex]

write an equation that passes through the point (3,-9) and is parallel to the x-axis
Answer:
y = -9
Step-by-step explanation:
Any line that is parallel to the x-axis has a slope of 0.
since the y-value in the point is -9, that is the y-intercept.
So, our equation is y = -9.

Charlie and Jasmine share cartons of apple juice. Charlie drinks 1/3 of a carton every day. Jasmine drinks 2/5 of a carton every day. Any apple juice left in a carton at the end of the day is used the following day. The cost of a carton is 70p. Charlie and Jasmine buy just enough cartons to last them for 10 days. How much do they spend in total for these cartons? Give your answer in £.
Using proportions, it is found that they spent a total of £5.6 for these cartons of apple juice.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the daily fraction of a carton they drink is given by:
[tex]\frac{1}{3} + \frac{2}{5} = \frac{5 + 6}{15} = \frac{11}{15}[/tex]
Hence, applying the proportion, over 10 days, the amount of cartons they drink is given by:
[tex]10 \times \frac{11}{15} = \frac{110}{15} = 7.33[/tex]
Rounding up, they buy 8 cartons, each at £0.7. Hence the total amount spent is given by:

In adjoining figure a circle is inscribed in the quadrilateral ABCD given that BC is equal to 38 cm cube is equal to 27 cm and BC equal to 25 cm and that ad is perpendicular to DC find the radius of the circle.
Step-by-step explanation:
Let O be the centre of the circle. Since P and S are the points of contact of tangents AD and DC respectively, OP ⊥ AD and OS ⊥ DC
Also, AD ⊥ DC (given), therefore, OPDS is a square.
BR = BQ = 27cm...(tangents from an external point to a circle are equal in length)
therefore, CR = CB - BR = (38 - 27)cm = 11cm
SC = CR = 11 cm...(tangents from an external point) therefore, DS = DC - SC = (25 - 11) cm = 14 cm.
therefore,
Radius of a circle = OP = DS = 14 cm...(therefore, OPDS is a square).
