Fencepost Problem: You need to build one side of a fence that is 12 yards long. This
fence will be built with fenceposts and rails that connect one fencepost to another. If
each fencepost is 1 yard away from the next fencepost, how many fenceposts will be
needed for this side of the fence? How many fenceposts will be needed for a side of
a fence that is N (where N > 0) yards long?

Answer:

y = 3/4x + 19/2

Step-by-step explanation:

m = 3/4. point (-6,5)

Point slope form:

y-5=3/4(x- -6)

y -5 = 3/4x + 18/4. 18/4 = 9/2

Y = 3/4x + 9/2 + 5. 5 times 2 plus 9 over 2 = 19/2

y = 3/4x + 19/2

Answer:

The numbers are 12 and 8

Step-by-step explanation:

let the numbers be x and y :

[tex]x + y = 20 - - - (a) \\ x - y = 4 - - - (b)[/tex]

add (a) and (b):

[tex]2x + 0y = 24 \\ 2x = 24 \\ x = 12[/tex]

find y:

[tex]x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8[/tex]

The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint

AB + BC = AC

9x + 7 + (-3x + 20) = 39

9x + 7 - 3x + 20 = 39

6x + 27 = 39

6x = 39 - 27

6x = 12

x = 12 / 6

x = 2

9x + 7 = - 3x + 20

9(2) + 7 = - 3(2) + 20

25 = 15

Hence,

Since, AB ≠ BC, then B is not the midpoint

Answer:

[tex]x=-\frac{5}{3}\quad \mathrm{or}\quad \:x=3[/tex]

Step-by-step explanation:

[tex]2\left|3x-2\right|=14[/tex]

⇒ Divide both sides by 2

[tex]\frac{2\left|3x-2\right|}{2}=\frac{14}{2}[/tex]

[tex]\left|3x-2\right|=7[/tex]

⇒ Now, apply absolute rule:- if |x|=a,a > a than x=a or x=-a

[tex]3x-2=-7\quad[/tex]

or...

[tex]3x-2=7[/tex]

Now,

[tex]3x-2=-7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=-7+2[/tex]

[tex]3x=-5[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{-5}{3}[/tex]

[tex]x=-\frac{5}{3}[/tex]

[tex]3x-2=7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=7+2[/tex]

[tex]3x=9[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{9}{3}[/tex]

[tex]x=3[/tex]

Answer:

Find the common difference and the next term of the following sequence:

3, 11, 19, 27, 35...

Step 1. To find the common difference, subtract any consecutive pair of terms.

11 - 3 = 8

19 - 11 = 8

27 - 19 = 8

35 - 27 = 8

The difference is always 8, so d = 8.

Step 2. Use the common difference to find the next term.

Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.

Step-by-step explanation:

mark me brainliest plz

Answer:

[tex]d = a_{2} - a _{1}[/tex]

d is the common difference

a1 is the first term, a1 = 27

a2 is the second term, a2 = 11

substitute:

Answer:

hope it helps you........

Step-by-step explanation:

The midpoint formula is

[tex] (\frac{x1 + x2}{2} ) \: and \: ( \frac{y1 + y2}{2} )[/tex]

Where (x1,y1) is one pair of the points and (x2,y2) is the other pair of points.

The points are

(-5,-4)

(-3,3) So the midpoint is

[tex]( \frac{( - 5 + ( - 3)}{2} )\: and \:( \frac{ - 4 + 3}{2} )[/tex]

Which gives us

[tex] - 4 \: and \: - 0.5[/tex]

So the midpoint is

(-4,-0.5)

Step-by-step explanation:

Answer:

The GCF is going to be 9

Step-by-step explanation:

When finding the GCF, you want to do prime factorization of each number.

18's prime factorization is, 2 × 3 × 3, which equals 18

36's prime factorization is 2 × 2 × 3 × 3, which equals 36

45's prime factorization is 5 × 3 × 3, which equals 45

Now all you have to do is find the factors common in each one, which is 2 three's. You then multiply 3 × 3 = 9. That is your answer

Answer:

It can't be expressed in that form

Step-by-step explanation:

From difference of two squares:

[tex]{ \boxed{(a + b)(a - b) = ( {a}^{2} - {b}^{2} )}}[/tex]

a » 9

b » 2i

[tex](9 + 2i)(9 - 2i) = \{ {(9)}^{2} - {(2i)}^{2} \} \\ \\ = (81 - 4 {i}^{2} )[/tex]

but i² is -1 [ complex numbers ]

[tex] = \{81 - 4( - 1) \} \\ = 81 + 4 \\ = 85[/tex]

Answer:

[tex](9 + 2i)(9 - 2i) \: \\ this \: can \: be \: wrtten \: as \: \\ {9}^{2} - {2i}^{2} = 81 - 4 \times - 1 \\ = 81 + 4 = 85 \\ then \: 85 + 0i \\ thank \: you[/tex]
