a. Divide: 21a3 by 3a? ? 2 b. Multiply: (2x+y) by (x-y) 3. a. Simplify: 3x+2y-2x+y
hellp mee plzz
Answer:
a .[tex] \frac{21 {a}^{3} }{3 {a}^{2} } = 7a[/tex]
b.[tex](2x + y)(x - y) \\ = 2 {x}^{2} - 2xy + xy - {y}^{2} \\ = 2 {x}^{2} - xy - {y}^{2} \\ [/tex]
a.[tex]3x + 2y - 2x + y \\ = x + 3y[/tex]
I hope I helped you^_^
Answer:
a = 7a, b = [tex]2x^2 - yx - y^2[/tex]
Step-by-step explanation:
a. 21 / 3 = 7. [tex]a^3 / a^2 = a[/tex] (exponents are basically subtracted when dividing), creating 7a
b. [tex](2x + y)(x-y)[/tex]
Use FOIL for this or use the distributive property, either way. Then combine like terms
[tex]2x^2 - 2xy + yx - y^2[/tex]
[tex]2x^2 - yx - y^2[/tex]

How would you describe the shape of the distribution of the data? How is it skewed?
a.
The distribution is not skewed at all.
b.
The distribution is somewhat skewed to the right.
c.
The distribution is somewhat skewed to the left.
d.
The distribution is symmetrical.
Answer:
the normal distribution is a symmetric distribution with no skew. ... A left-skewed distribution has a long left tail. Left-skewed distributions are also called negatively-skewed distributions. That's because there is a long tail in the negative direction on the number line.
Answer:
the answer is D
Step-by-step explanation:
because I'm right
Find the limits, if they exist lim(x,y)→(0,0) (3x^2/(4x^2+4y^2))
(1) Along the x-axis, we have y = 0, so that
[tex]\displaystyle\lim_{(x,y)\to(0,0)} \frac{3x^2}{4x^2+4y^2} = \lim_{x\to0} \frac{3x^2}{4x^2} =\lim_{x\to0}\frac34= \frac34[/tex]
(2) Along the y-axis, we take x = 0, then
[tex]\displaystyle\lim_{(x,y)\to(0,0)} \frac{3x^2}{4x^2+4y^2} = \lim_{y\to0} \frac0{4y^2} = 0[/tex]
(3) Along the line y = mx, we have
[tex]\displaystyle\lim_{(x,y)\to(0,0)} \frac{3x^2}{4x^2+4y^2} = \lim_{x\to0} \frac{3x^2}{4x^2+4(mx)^2} = \lim_{x\to0}\frac{3x^2}{4x^2+4m^2x^2} = \frac3{4+4m^2}[/tex]
which means the limit is dependent on the slope of the line m.
(4) nonexistent
g(x) = sqr root of x+3
What is the domain of g?
Answer:
[tex]all \: real \: numbers \: except \: \\ x + 3 < 0 \\ \: \: \: \: x < - 3[/tex]
Answer:
X is the domain and sqr root of X+3 is the range.

In the Tigers Football Club, there are 9 players to each coach, while in the Eagles Football Club, there are 17 players to every 2 coaches. If the total number of players and coaches in the two clubs is 232, how many players and coaches are in each club?
9514 1404 393
Answer:
Tigers: 8 coaches, 72 playersEagles: 16 coaches, 136 playersStep-by-step explanation:
We can define a "basic unit" of each team to be the minimum number of players and coaches that can have the given ratio. For the Tigers, that is 1 coach and 9 players, for a total of 10 team members. For the Eagles, that is 2 coaches and 17 players, for a total of 19 team members. If we have t basic units of Tigers and e basic units of Eagles, then we want ...
10t +19e = 232 . . . . . the total of players and coaches in the two clubs
We want t and e to be integers, so this is a Diophantine equation. It can be solved any of several ways, including use of the Extended Euclidean Algorithm. Here, we'll make some observations based on "number sense."
The value of e must be an even number between 0 and 232/19 = 12. The product of e and 19 must be a number that ends in 2, because 10t will end in 0, and the sum with 19e must end in 2.
The only multiple of 9 that ends in 2 is 9×8 = 72, so the value of e must be a positive number less than 12 that ends in 8. We must have e=8.
Then t=(232 -8×19)/10 = 8. This tells us there are 8 "basic units" of each team.
The Tigers have 8 coaches and 72 players.
The Eagles have 16 coaches and 136 players.

21. Six more than three times a number is equal to the number itself. Write the equation and find the number.
Answer:
-3
Step-by-step explanation:
6 + (six more) 3x (3 times a number) = x (is equal to the number)
6 + 3x = x
6 + 2x = 0
2x = -6
x = -3

14.127 divided by 5.1 show work
9514 1404 393
Answer:
2.77
Step-by-step explanation:
Usually we like to do long division with the divisor being an integer. Here, that means the decimal points in both numbers are moved one place to the right. This makes the division be 141.27/51 = 2.77. The work is shown in the attachment.
