Answer:
The expression is missing in the question.
The expression is 4x +450
The variable is x and the coefficient is 4
Step-by-step explanation:
In an expression, a variable is a quantity which is not fixed value and can be of any arbitrary value. A variable is the unknown in the expression. In any expression, the variable are represented by alphabets such as a, b, c, x, y or z etc.
The numeric quantity which lies in the front of a variable is known as a coefficient. It can be any numeric values. For example, 9x --- here 9 is the coefficient of variable x, 4x -- here 4 is the coefficient.

Pls help with this!!!
Answer:
a. Yes
b. Yes
c. Yes
d. Degree 8
Step-by-step explanation:
a. Yes, n(x) is a polynomial of one single term (also called monomial) because it contains variables raised to positive integers.
b. Yes, m(x) is a polynomial of also one single term (also called monomial) because it contains variables raised to positive integers.
c. The quotient of n(x) / m(x) can be reduced to a polynomial of one single term as follows:
[tex]\frac{n(x)}{m(x)} =\frac{6\,x^5\,y^7}{2\,x^3\,y} =3\,x^2\,y^6[/tex]
which as can be seen, also contains variables raised to positive integers.
d. The degree of the polynomial resultant is the addition of the powers of all variables present (x and y) which results in: 2 + 6 = 8
Therefore the degree of this polynomial is 8.
hello there >3 i would like explanation for this :)
Answer:
75
Step-by-step explanation:
Let t and u represent the tens and units digits, respectively.
t = u + 2 . . . . the tens digit exceeds the units digit by 2
t + 2u = 17 . . . . the sum of the tens digit and twice the units digit is 17
Substituting for t in the second equation, we get ...
(u +2) +2u = 17
3u = 15 . . . . . . . . subtract 2
u = 5 . . . . . . . . . . divide by 3

Answer:
Reflect over the X-axis, then translate (x+6, y+3)If m∠JKM = 43, m∠MKL = (8 - 20), and m∠JKL = (10x - 11), find each measure.
1. x = ?
2. m∠MKL = ?
3. m∠DEF = ?
Correct Question: If m∠JKM = 43, m∠MKL = (8x - 20), and m∠JKL = (10x - 11), find each measure.
1. x = ?
2. m∠MKL = ?
3. m∠JKL = ?
Answer/Step-by-step explanation:
Given:
m<JKM = 43,
m<MKL = (8x - 20),
m<JKL = (10x - 11).
Required:
1. Value of x
2. m<MKL
3. m<JKL
Solution:
1. Value of x:
m<JKL = m<MKL + m<JKM (angle addition postulate)
Therefore:
[tex] (10x - 11) = (8x - 20) + 43 [/tex]
Solve for x
[tex] 10x - 11 = 8x - 20 + 43 [/tex]
[tex] 10x - 11 = 8x + 23 [/tex]
Subtract 8x from both sides
[tex] 10x - 11 - 8x = 8x + 23 - 8x [/tex]
[tex] 2x - 11 = 23 [/tex]
Add 11 to both sides
[tex] 2x - 11 + 11 = 23 + 11 [/tex]
[tex] 2x = 34 [/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{34}{2} [/tex]
[tex] x = 17 [/tex]
2. m<MKL = 8x - 20
Plug in the value of x
m<MKL = 8(17) - 20 = 136 - 20 = 116°
3. m<JKL = 10x - 11
m<JKL = 10(17) - 11 = 170 - 11 = 159°
The vertices A, B, C of a triangle are (2,1),(5,2),and (3,4) respectively . Find the coordinate of the circumcentre and also the radius of the circum-circle of the triangle
Answer:
Circumcenter = (4,0)
Circumcircle = √5
Step-by-step explanation:
The circumcentre is the point of intersection of the perpendicular bisectors of a triangle. The vertices of the triangle are equidistant to the circumcentre.
Let us assume the coordinate of the circumcentre is at O(x, y). Therefore the distance between the cirmcumcenter and the vertices are:
[tex]AO=\sqrt{(x-2)^2+(y-1)^2} =\sqrt{x^2-4x+4+(y^2-2y+1)}\\=\sqrt{x^2+y^2-4x-2y+5} \\\\BO=\sqrt{(x-5)^2+(y-2)^2} =\sqrt{x^2-10x+25+(y^2-4y+4)}\\=\sqrt{x^2+y^2-10x-4y+29} \\\\CO=\sqrt{(x-3)^2+(y-4)^2} \\=\sqrt{x^2-9x+9+(y^2-8y+16)}=\sqrt{x^2+y^2-9x-8y+25} \\[/tex]
AO = BO, therefore
√(x² + y²-4x-2y+5) = √(x² + y² - 10x - 4y + 29)
x² + y²-4x-2y+5 = x² + y² - 10x - 4y + 29
6x + 2y = 24 (1)
BO = CO
√(x² + y² - 10x - 4y + 29) = √(x² + y² - 9x - 8y + 25)
x² + y² - 10x - 4y + 29 = x² + y² - 9x - 8y + 25
-x + 4y = -4 (2)
Multiply equation 2 by 6 and add to equation 1:
26y = 0
y=0
Put y = 0 in -x + 4y = -4
-x + 4(0) = -4
x = 4
The cicumcenter is at (4, 0)
The radius of the circumcircle = AO = BO = CO. Therefore:
[tex]Radius=AO=\sqrt{(4-2)^2+(0-1)^2} =\sqrt{4+1}=\sqrt{5}[/tex]

Elle and Jude formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively.If the end of the year Jude received $5000.00 more than Elle how much was Elle's share
Answer:
$20000
Step-by-step explanation:
Let Elle received $x
Therefore, Jude received (x + 5000)$
[tex] \because x : (x + 5000) = 4 :5[/tex]
[tex] \therefore \frac{x}{(x + 5000)} = \frac {4}{5}[/tex]
[tex] \therefore 5x = 4(x + 5000)[/tex]
[tex] \therefore 5x = 4x + 20000[/tex]
[tex] \therefore 5x - 4x = 20000[/tex]
[tex] \therefore x = \$20000[/tex]
Therefore, Elle's share = $20000

Both the Galapagos Islands and the island of Naura are on the equator, but the Galapagos Islands are at 90.30°W whereas the island of Naura is at 166.56°E. How far is it from the Galapagos Islands to Naura traveling over the Pacific ocean along the equator, correct to the nearest km?
Answer:
11521 km
Step-by-step explanation:
The computation is given below:
But prior to reaching the final solution first the following calculations need to be computed
Angle between the Galapagos and Nauru is
= 90.30° + 166.56°
= 256.86°
As we know that the total of angles is 360 degrees
Now the major arc and the minor arc is
= 360° - 256.86°
= 103.14°
So, the angles between galapagos islands is
= 180° - 90.30°
= 89.70°
And, angles between the naura island is
= 180° - 166.56°
= 13.44°
Now the sum of this two island is
= 89.70° + 13.44°
= 103.14°
Therefore The length is
[tex]= \frac{\pi r}{180^{\circ}} \times \theta \\\\ = \frac{6,400 \pi}{180^{\circ}} \times 103.14^{\circ}[/tex]
= 11521 km

Suppose you invested $1500 in the stock market 2 years ago. During the first year, the value of the stock increased by 16%. During the second year, the value of the stock decreased by 16%. How much money is your investment worth at the end of the two-year period? (Note: The answer to this question is not $1500.)
Answer:
$1,461.60
Step-by-step explanation:
Value of the stock in the first year if value increased by 16% = 1500 x (1.16) = $1740
1.16 = 100% + 16% = 116%
Value of the stock in the second year if value decreased by 16% = $1740 x 0.84 = $1,461.60
0.84 = 100% - 16% = 84%

Mr. Ondonez gives his math students 34 quizzes during 17 weeks of school if he gave the same number because it each week how many quizzes does Mr.Ondonez give his students every week
Answer:
2 quiz
Step-by-step explanation:
Mr Ondonez gives his students 34 quizzes over 17 weeks. They are given the same number of quiz per week. To calculate the number of quiz given per week, we have to divide the total number of quiz given by the total number of weeks. Therefore:
Number of quiz per week = Total number of quiz / Total number of weeks
Number of quiz per week = 34 / 17 = 2
The students are given 2 quizzes per week.

Which number is not written in scientific notation
Answer:
D. 15x10^20
Step-by-step explanation:
The rule for scientific notation is that the coefficient has to be between 1 and less than 10. This means there is only one digit in front of the decimal. 15x10^20 should be written as 1.5x10^21 to follow the rule.
Answer:
Hey there!
e15 times 10^20 isn't written in scientific notation. For a number to be in scientific notation, the leading number must be between 1 and 10.

Chiang is filling a 50 ft3 container with water at a rate of 0.5 ft3/min. Interpret
the key features for this situation.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the expression :
Chiang is filling a 50 ft3 container with water at a rate of 0.5 ft3/min. Interpret
50 ft^3 represents the volume of the container which is a product of its length, width and height. The rate is said to be 0.5ft^3 /min. The stated rate represents the volume of the container which Chiang fills each minute. The rate could be obtained by taking the proportion of the entire volume of the container and the time it takes Chiang to fill it.
Here, it will be :
Rate = ( volume of container (ft^3) / time taken (minutes))
Hence 0.5ft^3/min means on average Chiang's fills a volume of 0.5ft^3 of the container each minute.

The original expression simplifies to -4 which is part of the set of integers {..., -3, -2, -1, 0, 1, 2, 3, ...}
We can write -4 as a fraction of two integers -4 = -4/1, so it is also a rational number.
Because it's rational, it cannot be irrational.
The set of whole numbers is {0, 1, 2, 3, ...} which doesn't involve negative values. If you want to include negative values, then use the set of integers.

Which numbers produce an irrational number when added to 5/8
Answer:
Irrational numbers
Step-by-step explanation:
Any irrational number plus a rational number like (5/8) creates another irrational number.
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
An irrational number is a number that cannot turn into a fraction.
If you add an irrational number to a rational number, the sum is an irrational number because since the number cannot be ended and/or written into a fraction.
Irrational numbers are: Pi and infinity. Pi doesn't ever end, and all the digits (after 0) are different (it's a formula). Infinity has no end, so you cannot write infinity as a fraction.
Pi plus 5/8 is an irrational number.
Infinity plus 5/8 is also an irrational number.
