Answer:  The correct option is

(A) (11, 3).

Step-by-step explanation:  We are given to find the co-ordinates of he point that is one-sixth of the way from A(14, −1) to B(−4, 23).

As shown in the attached figure below, let point P is one-sixth of the way from A to B.

Also, let P divides the the segment AB in the ratio m : n.

Then, we must have

\dfrac{m}{m+n}=\dfrac{1}{6}\\\\\\\Rightarrow 6m=m+n\\\\\Rightarrow 6m-m=n\\\\\Rightarrow 5m=n\\\\\Rightarrow \dfrac{m}{n}=\dfrac{1}{5}\\\\\Rightarrow m:n=1:5.

So, the point P divides AB in the ratio 1 : 5.

We know that

if a point divides the line segment joining the points (a, b) and (c, d) in the ratio m : n, then its co-ordinates are

\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).

Therefore, the co-ordinates of the point P will be

\left(\dfrac{1\times(-4)+5\times14}{1+5},\dfrac{1\times23+5\times(-1)}{1+5}\right)\\\\\\=\left(\dfrac{-4+70}{6},\dfrac{23-5}{6}\right)\\\\\\=\left(\dfrac{66}{6},\dfrac{18}{6}\right)\\\\=(11,3).

Thus, the required co-ordinates of the point is (11, 3).

Option (A) is CORRECT.

Split the second term in 3a^2 - 8a + 4 into two terms

3a^2 - 2a - 6a + 4 = 0

Factor out common terms in the first two terms, then in the last two terms.

a(3a - 2) -2(3a - 2) = 0

Factor out the common term 3a - 2

(3a - 2)(a - 2) = 0

Solve for a;

a = 2/3,2

<u>Answer : B. (2/3,2)</u>

A spinner is divided into eight equal-sized sections, numbered 1 to 8, inclusive. What is true about spinning the spinner one at
zvonat [6]

Answer with explanation:

The number of section into which Spinner is divided =Number from 1 to 8={1,2,3,4,5,6,7,8}

Now, Spinner is Spun once .

The Correct statement among the given statements are:

→1.   S={1,2,3,4,5,6,7,8}

→2. If A is a subset of S, A could be {1,2,3} , because , {1,2,3}⊂{1,2,3,4,5,6,7,8}.

→5.If a subset A represents the complement of spinning an odd number, it’s sample space is A={2,,4,6,8}

A=odd number={1,3,5,7}

A's Complement=Even Number={2,4,6,8}

Why, not 3 and 4, because, The number of elements in the set is from 1 to 8, but the subset has three elements, 7,8, and 9.Element, 7 ∈ S, 8∈S, but , 9∈S.

Also, number less than 4, is equal to ={1,2,3}, but in the statement, it is given that,number less than 4, it’s sample space is A={1,2,3,4},which is Incorrect.

Pls only do this if yk it because i’m giving correct answer brainliest! :))

Answer:

x=2+\frac{1}{2}\sqrt[]{21}

or

x=2-\frac{1}{2}\sqrt{{21}

Step-by-step explanation:

4x^2-16x-26=-21

Add 21 on both sides.

4x^2-16x-26+21=-21+21

4x^2-16x-5=0

a=4

b=-16

c=-5

x=\frac{-b\frac{+}{}\sqrt[]{b^2-4ac}  }{2a}

x=\frac{-(-16)\frac{+}{}\sqrt[]{(-16)^2-4(4)(-5)}  }{2(4)}

x=\frac{16\frac{+}{}\sqrt[]{256+80}  }{8}

x=\frac{16\frac{+}{}\sqrt[]{336}  }{8}

x=\frac{16\frac{+}{}\sqrt[]{2^2*2^2*21}  }{8}

x=\frac{16\frac{+}{}2*2\sqrt[]{21}  }{8}

x=\frac{16\frac{+}{}4\sqrt[]{21}  }{8}

---------------------------------------------------------------------------

x=\frac{16}{8}+\frac{4\sqrt[]{21}}{8}

x=2+\frac{1}{2}\sqrt[]{21}

---------------------------------------------------------------------------

x=\frac{16}{8}-\frac{4\sqrt[]{21}}{8}\\x=2-\frac{1}{2}\sqrt{{21}

1/4x + 1 + 3/4c - 2/3 - 1/2x<br><br> what is it equal to??
mylen [45]

Answer: -1/4x+1/3+3/4c

Step-by-step explanation:

<h2>We can't solve it but we can simplify</h2>
  1. 1/4x+1+3/4c-2/3-1/2x, try to move the equation around. Since the operations are in the same level we can do that.
  2. 1/4x-1/2x+(1-2/3)+(3/4c), 1/4 minus 1/2 can be written as 0.25-0.50 which is -0.25 or -1/4 don't forget to add x (we can do this since there like terms)
  3. -1/4x+(1-2/3)+(3/4c), now we can convert 1 into a fraction which will become 3/3, so we can rewrite is as 3/3-2/3, which is 1/3
  4. -1/4x+1/3+3/4c, We can't simplify anymore so this is our final answer.

one number is three more than four time another if the sum of the two number is 23 then find both numbers
zloy xaker [14]
<h3><u>The value of x is 19.</u></h3><h3><u>The value of y is 4.</u></h3>

x = 3 + 4y

x + y = 23

Because we have a value for x we can plug it directly into the second equation.

3 + 4y + y = 23

Subtract 3 from both sides.

4y + y = 20

Combine like terms.

5y = 20

Divide both sides by 5.

y = 4

Plug this value for x back into the original equation.

x = 3 + 4(4)

x = 3 + 16

x = 19
