Answer:

14 - 13x

Step-by-step explanation:

take 13x + 1 away from 15

15 - (13x + 1) =  15 - 13x - 1  =  14 - 13x

The value of x is 1/2 and the measure of MG is 7.5 cm.

Given that, M is the midpoint of FG.

We need to find the measure of MG and FM.

In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

Now, FG=MG+FM

⇒FG=MG+MG (MG=FM)

⇒FG=2MG

⇒15=2(13x+1)

⇒15=26x+2

⇒x=1/2

Now, MG=FM=13(1/2)+1=7.5 cm

Therefore, the value of x is 1/2 and the measure of MG is 7.5 cm.

Step-by-step explanation:

Given (12^13–12^12+12^11)(11^9–11^8+11^7),

(12^13–12^12+12^11)(11^9–11^8+11^7) =

[(12^12)12 – 12^12 + 12^11][(11^8)11 – 11^8 + 11^7)

[(12^12)(12 – 1) + 12^11][(11^8)(11 – 1) + 11^7] =

(12^12(11) + 12^11)(11^8(10) + 11^7) =

(12^11(12x11) + 12^11)(11^7(11x10) + 11^7) =

[(12^11)(12x11 + 1)][(11^7)(11x10 + 1)] =

[(12^11)x(11^7)](12x11 + 1)(11x10 + 1) =

[(12^11)x(11^7)](133 x 111) =

I got the answer from Hegarty

There are different 4-digit PIN codes are there that only include the digits 3, 4, 6, 7, 9 and 2.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Numbers to make 4 - digit PIN codes are,

⇒ 3, 4, 6, 7, 9 and 2.

Now,

Since, There are 6 number to choose to make 4 - digit PIN codes.

Hence, Number of different choices to make 4 - digit PIN codes is,

⇒ [tex]^6P_{4} }[/tex]

⇒ 6! /  (6-4)!

⇒ 6! / 2!

⇒ 6 × 5 × 4 × 3 × 2! / 2

⇒ 360

Thus, There are 360 choices to make 4 - digit PIN codes.

Answer:

One hosta = $ 12 , One shrub = $ 5

Step-by-step explanation:

Let;

x = hostas

y = shrubs

Emily spent $132 on 6 hostas and 12 shrubs.

6x + 12y = 132 ........................................ (i)

Chelsea spent $213 on 14 hostas and 9 shrubs

14x + 9y = 213 ........................................ (ii)

From (i)

12y = 132 - 6x

y = 11 - 0.5x  ........................................ (iii)

substitute (iii) into (ii)

14x + 9 (11 - 0.5x) = 213

14x + 99 - 4.5x = 213

9.5x = 114

x = $ 12

Substitute value of x in (iii)

y = 11 - 0.5(12)

y = 11 - 6 = $ 5

Answer:

The mean height is 3.2 feet and thestandard deviation 0.6 feet. A… ... A forest ranger has data on the heights of a large growth ... mately what fraction of the trees should we expect to be.

The  fraction of the trees that is between 4.0 and 4.4 feet is 7%

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

x is the raw score, μ is mean and σ is standard deviation

Given that μ = 3.2, σ = 0.6, hence:

[tex]For\ x = 4:\\\\z=\frac{4-3.2}{0.6} =1.33\\\\\\For\ x = 4.4:\\\\z=\frac{4.4-3.2}{0.6} =2[/tex]

From the normal distribution table, P(4 < x < 4.4) = P(1.33 < z < 2) = P(z < 2) - P(z < 1.33) = 0.9772 - 0.9082 = 7%

The  fraction of the trees that is between 4.0 and 4.4 feet is 7%

  6 : 5

Step-by-step explanation:

The diagram shows you that the boxes have a length (L) to width (W) ratio such that ...

  3L = l = 4W

  L/W = 4/3

Suppose we call the width of the box 3 units, then its length is 4 units, and we have the crate dimensions ...

  l = 4(3) = 3(4) = 12

  w = 3+3+4 = 10

Then the ratio l : w is 12 : 10 = 6 : 5.

Answer:

A

Step-by-step explanation:

The expression for the width of rectangular placemats is (9x - 25) units.

Given that, the area of rectangular placemats=45x²-70x-150.

The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'. So, the area of the rectangle = (a × b) square units.

Now, 45x²-70x-150=(5x + 6)×b

⇒b=45x²-75x-150/(5x + 6)

⇒b=(5x + 6)(9x - 25)/(5x + 6)

⇒b=(9x - 25)

Therefore, the expression for the width of rectangular placemats is (9x - 25) units.

5x+1=36 then do substitution

-1 from both sides (from +1 you gotta do the inverse)

Okay so I’m gonna do a few and list a few examples

In slope intercept form its

y=mx+b

Y= Random Y coordinate (Not that important for now while writing)

m= Slope

X= random x coordinate (not that important for now while writing)

b= Y intercept

SO basically plug it in like that so for the first one

the slope is 1/3  and y-intercept is -1

so

y=1/3x-1

And thats how you do it

leave the y and x

Graphing

So for graphing or fining the equation, first identify the y-intercept

The y-intercept is on the y axis (obviously), and its the number where the line first hits, so for the first one, the y intercept is 3 becuase thats where the first line meets on the Y axis. When identified start doing rise over run, lik just go up and right, if there is no space, dot he opposite, go down and go left or right (depends if the line is rising or falling, you can tell if rising (positive) if the line goes from down to up form left to right , if falling (negative) vice versa, up to down from left to right). And just write the equation after identifying the slope And y-intercept, the x and y don’t matter.

4) y= -1/3x+3 (watch your signs, if falling the slope is automatically negative)

5) y=1/2x+1

6) y=4x-5 (negative y-intercept due to the part where the y meets up with the line, its in the negative side)

The property used is Symmetric property of Equality.

Option B is correct option.

Step-by-step explanation:

We are given :

[tex]AR \cong TY\\[/tex]

Which property will give the step:

[tex]TY \cong AR\\[/tex]

Looking at the options:

We see that Symmetric property states that if a = b then b= a

Same is the case with the question.

We have :

[tex]AR \cong TY\\\\TY \cong AR\\[/tex]

If a = AR and b = TY

then the property is: a = b, b=a
