Which Expression represents the perimeter of the figure below?

А 5x+2y
B x + y +z
C 5x + 2y + 2
D (5+2 + 1)(x + y + 2)

Answer:

4 years

Step-by-step explanation:

basically, multiple 16,250 by 107.9%, get the product and multiply that product by 107.9%+ 7.9% and keep on doing that until you eventually get to about 33,000 which is a bit more than double 16,250 but 4 years is still the minimum years it will take to get AT LEAST double. :)

Answer:

[tex]\displaystyle \large{x=\dfrac{1}{7}}[/tex]

Step-by-step explanation:

Given:

Answer:

y = 2/5 x + 4/5

Step-by-step explanation:

First, we find the slpe of the line that is shown.

We go from point (-2, 2) to (0, -3).

We go 5 down, or a rise of -5.

Then we go 2 right, or a run of 2.

slope = m = -5/2

The perpendicular line has slope 2/5.

y = (2/5)x + b

2 = (2/5)(3) + b

10/5 = 6/5 + b

b = 4/5

y = 2/5 x + 4/5

Transforming the points involves changing their coordinates

The image of the points are:  (3, 6), (-11, 12) and  (-3, -12)

The coordinates of the points are given as:

X(2, 4)

Y(5,-3)

Z(-7, 1)

The rule of this transformation is:

(x, y) to (y, -x)

So, we have:

X' = (4, -2)

Y' = (-3, -5)

Z' = (1, 7)

The rule of this transformation is:

(x, y) to (2x, 2y)

So, we have:

X'' = (8, -4)

Y'' = (-6, -10)

Z'' = (2, 14)

The rule of this transformation is:

(x, y) to (x, -y)

So, we have:

X''' = (8, 4)

Y''' = (-6, 10)

Z''' = (2, -14)

The rule of this transformation is:

(x, y) to (x -5, y + 2)

So, we have:

X'''' = (3, 6)

Y'''' = (-11, 12)

Z'''' = (-3, -12)

Hence, the image of the points are:  (3, 6), (-11, 12) and  (-3, -12)

Answer:

x = -2 - i,  -2 + i.

Step-by-step explanation:

3x2 = -12x - 15

3x^2 + 12x + 15 = 0

Divide through by 3:

x^2 + 4x + 5 = 0

x^2 + 4x = -5

Completing the square:

x^2 + 4x + 4 = -5 + 4

(x + 2)^2 = -1

x + 2 =  √-1 = i

x = -2 - i, -2 + i.

Answer:

11000 pounds

Step-by-step explanation:

1 US ton=2000 pounds

multiply the mass value by 2000

5.5ton x 2000pound

=11000pounds

Answer:

That would be :

4x – 10 = x2 – 5x + 10  ( y = 4x - 10 is substitute for y)

PROOF:        y + 5x = x² + 10

                    (4x - 10) + 5x = x² + 10

                     4x - 10  =  x² -5x + 10

   0 = x2 – 9x + 20  (liked terms are grouped and simplified)

PROOF:      4x - 10  =  x² -5x + 10

                  4x = x² -5x + 10 + 10

                   0  = x² -5x -4x + 20

                   0  = x² - 9x + 20

Solving:

            x² - 9x + 20 = 0

            x² - 5x - 4x + 20 = 0

            (x - 5) (x - 4)  = 0

         ⇒ x = 4  (as question says) OR x = 5

Answer: 7.4.

Step-by-step explanation: To find the area of a triangle, you need the base, height, and then divide the results by two.  The following is done below:

A = h x b / 2, where h is the height, b is the base, and A is the area of the triangle.

A = 3.7 x 4 = 14.8.  

Next, 14/8 / 2 = 7.4.

Therefore, 7.4 is your answer.

Answers:

Sample Variance = 31.03

Sample Standard Deviation = 5.57

See the table below.

===================================================

Explanation:

M refers to the midpoint of each interval. The midpoint is [tex]M = \frac{a+b}{2}[/tex] where a,b are the left and right endpoints.

For example, [tex]M = \frac{0+4}{2} = \frac{4}{2} = 2[/tex] in the first row.

Multiply the frequency with the midpoint to get the third column. Summing this column of values leads to 4+49+180+153+154 = 540 shown at the bottom of that column.

Divide this sum over the sum of the frequencies (2+7+15+9+7 = 40) and we arrive at [tex]\overline{x} = \frac{540}{40} = 13.5[/tex] which is the sample mean xbar.

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

After we determine xbar, we subtract it from each value of M. Then we square the result to get [tex](M - \overline{x})^2[/tex]. Multiply that with the column f to get the new column [tex]f(M-\overline{x})^2[/tex].

This column is added to arrive at 1210 shown in the table below. Divide this over the sum of the frequencies minus 1. So we divide by n-1 = 40-1 = 39 to get roughly 31.03

This is the sample variance.

The square root of this is sqrt(31.03) = 5.57 and this is the approximate sample standard deviation.

Answer:

x = -5

Step-by-step explanation:

Given:

[tex]\displaystyle \large{8x-5=5(x-4)}[/tex]

Distribute 5(x-4):

[tex]\displaystyle \large{8x-5=5x-20}[/tex]

Add both sides by 5:

[tex]\displaystyle \large{8x-5+5=5x-20+5}\\\displaystyle \large{8x=5x-15}[/tex]

Subtract both sides by 5x:

[tex]\displaystyle \large{8x-5x=5x-15-5x}\\\displaystyle \large{3x=-15}[/tex]

Divide both sides by 3:

[tex]\displaystyle \large{\dfrac{3x}{3}=\dfrac{-15}{3}}\\\displaystyle \large{x=-5}[/tex]

Therefore, your solution is x = -5

Answer:

x = -5

Step-by-step explanation:

The diagonals of an isosceles trapezoid are congruent , then

x + 3 = 6 ( subtract 3 from both sides )

x = 3

So

#1

More words=25-15=10

Cost:-

#2

Extra words=50-15=35

Cost:-

Answer:

a. $17.50

b. $31.25

Step-by-step explanation:

a.

For $12 you get 15 words.

For a 25-word ad, you need 10 more words than the 15 you get for $12, so you must add 10 words at $0.55 per word.

cost = $12 + 10 × $0.55

cost = $12 + $5.5

cost = $17.50

b.

50 words is 25 words more than 25 words, so you must pay for 25 words more than the cost of the 25-word ad in part a.

cost = $17.50 + 25 × $0.55

cost = $17.50 + $13.75

cost = $31.25

Converting a decimal to a fraction :

A. (0.47)

B. (-0.47)

C. (0.--47)

Answer:

Part (a) = 47/100, Part (b) = -47/100, Part (c) = 47/100

Step-by-step explanation:

Step 1:  Determine 0.47 as a fraction

0.47 can also be expressed as 47% which means that there is 47/100.  We can see that there is no way that we can simplify the fraction even more so that is our final answer.

Step 2:  Determine -0.47 as a fraction

0.47 can also be expressed as -47/100.  We can see that there is no way that we can simplify the fraction even more so that is our final answer.

Step 3:  Determine --0.47 as a fraction

Two negatives (-), means that they cancel out and cause a positive (+).  For example, -1 * -1 gives us 1.  Therefore it would just be like the first one which is 47/100.

Answer: Part (a) = 47/100, Part (b) = -47/100, Part (c) = 47/100

Answer:

The image of DEFG forms QUADRILATERAL SHAPE

Answer:

11.7

Step-by-step explanation:

Since we know what the price was after the discount, we just have to reverse it. In order to apply a discount to a price, you multiply the number by the discount. e.g, 0.40 * x = 4.68. So to find the original price, we have to do the opposite. The opposite of multiplication is division, so divide 4.68 by 0.40, (0.40 is equivalent to 40%.) and we get 11.7.

11.7 is the original price.

Answer:

15

Step-by-step explanation:

First we can make an equation by replacing the unknown number with x :

First step of problem:

x-6

Second part of problem:

4(x-6)

Third part of the problem:

4(x-6)=36

First we can expand the bracket to give us:

4x-24=36

Now we add 24 to both sides:

4x = 60

Now we divide both sides by 4 for our final answer of

x= 15

To check this answer we can put it back into the problem:

4(15-6)=36

4(9)=36

✅

Therefore our answer that was thought was 15.

Answer:

[tex]\left(\dfrac53,\dfrac{14}{3}\right)[/tex]

Step-by-step explanation:

Equation 1:  y = 4x - 2

Equation 2:  y = x + 3

Subtract Equation 2 from Equation 1 and solve for x:

⇒ 0 = 3x -5

⇒ 3x = 5

⇒ x = 5/3

Substitute found value of x into one of the equations and solve for y:

⇒ y = 5/3 + 3

⇒ y = 14/3

Answer:

x= -3

Step-by-step explanation:

Solve the following system:

{8 y + 4.2 x = 41.8

y - 4.2 x = 19.4

In the second equation, look to solve for y:

{8 y + 4.2 x = 41.8

y - 4.2 x = 19.4

y - 4.2 x = y - (21 x)/5 and 19.4 = 97/5:

y - (21 x)/5 = 97/5

Add (21 x)/5 to both sides:

{8 y + 4.2 x = 41.8

y = 1/5 (21 x + 97)

Substitute y = 1/5 (21 x + 97) into the first equation:

{4.2 x + 8/5 (21 x + 97) = 41.8

y = 1/5 (21 x + 97)

4.2 x + (8 (21 x + 97))/5 = ((168 x)/5 + 776/5) + 4.2 x = 37.8 x + 776/5:

{(37.8 x + 776/5) = 41.8

y = 1/5 (21 x + 97)

In the first equation, look to solve for x:

{37.8 x + 776/5 = 41.8

y = 1/5 (21 x + 97)

37.8 x + 776/5 = (189 x)/5 + 776/5 and 41.8 = 209/5:

(189 x)/5 + 776/5 = 209/5

Subtract 776/5 from both sides:

{(189 x)/5 = -567/5

y = 1/5 (21 x + 97)

Multiply both sides by 5/189:

{x = -3

y = 1/5 (21 x + 97)

Substitute x = -3 into the second equation:

Answer: {x = -3, y = 34/5
