six less than the sum of a number and seven is twice the difference of the same number and 12

Answer:

y=x−3

Step-by-step explanation:

x−y=3

Step 1: Add -x to both sides.

x−y+−x=3+−x

−y=−x+3

Step 2: Divide both sides by -1.

−y/−1=−x+3/1

y=x−3

Answer:

i = -6

Step-by-step explanation:

3 - 2i + 8 = 23

3 + 8 - 2i = 23

11 - 2i = 23

11 - 11 - 2i = 23 - 11

-2i = 12

-2i ÷ -2 = 12 ÷ -2

i = -6

Answer:

A. Yes

B. No

C. Yes

D. Yes

E. No

F. Yes

Step-by-step explanation:

A Write the equation 3n + 4 + 6 = 2n – 14. Yes

B Write the equation 3(n + 4) + 6 = 2(n – 14). No

C Combine like terms. Yes

D Subtract 2n from each side. Yes

E Add 10 to each side. No

F Subtract 10 from each side. Yes

Solution:

sum of 3 times a number and 4 is increased by 6, the result is 2 times a number decreased by 14

Let the number = n

{(3 * n) + 4} + 6 = (2 * n) - 14

3n + 4 + 6 = 2n - 14

3n + 10 = 2n - 14

3n + 10 - 2n = 2n - 14 - 2n

n + 10 = -14

Subtract 10 from each side

n + 10 - 10 = -14 - 10

n = -24

Answer:

the area is 43cm²

Step-by-step explanation:

First, you find the area of the left side. 7cm - 3cm= 4cm

Secondly, you multiply 4cm x 4cm = 16cm

Then, you find the area of the bottom bit. 9cm x 3 cm = 27cm

Lastly, you add 27cm + 16cm, which brings your answer to...

43cm² :-)

(It's squared because you are finding the area)

If it is tens its 20

If it ins tenth its 19.8

To round 19.798 to the nearest tenth consider the hundredths’ value of 19.798, which is 9 and equal or more than 5. Therefore, the tenths value of 19.798 increases by 1 to 8.

19.798 rounded to the nearest tenth = 19.8

Answer:

19.8

Step-by-step explanation:

I'm not sure if you mean "tens" or "tenths" so I assumed "tenths".

If it was "tens" then it would be 20.

Step-by-step explanation:

4x²- 12x + 9 = 5

4x²- 12x + 4 = 0

devided by 4

x²-3x+1=0

x = (3 ± √9-4)/2 = (3±√5)/2

x = (√5+3)/2 or x= (-√5+3)/2

Answer: (0, 10) or 10

Step-by-step explanation:

plug 0 into y

(0) = 1/2x - 5

1/2x - 5 = 0

      + 5 + 5

1/2x = 5

* 2    * 2

x = 10

The mean, median, and mode of the data will be 41.111, 40, and 51 respectively.

Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect and summarise the data.

The data is given below.

63, 40, 51, 70, 36, 21, 51, 28, 19

Arrange the data in ascending order, then we have

19, 21, 28, 36, 40, 51, 51, 63, 70

Then the mean of the data is given as,

Mean = (19 + 21 + 28 + 36 + 40 + 51 + 51 + 63 + 70) / 9

Mean = 379 / 9

Mean = 42.11

The median of the data is the middle term of the data which is 40.

The mode is 51 because the number frequency of 51 is the highest.

Answer:

In this question you got multipel answers.

If she buys as much pants as she can;

135 - (15.p) = 5.s

135 - (15.9) = 0

so now she has bought no shirts and 9 pants.

if she buys as much shirts as she can;

135 - (5.s) = 15.p

135 - (5.27) = 0

so now she has bought no pants and 27 shirts.

If she wants a shirt for each pants the equation would look something like this;

p=s=x

135 - (15.x) = 5.x

but with each pants she can buy three shirts, so 9 = 3.3

(7.15)+(6.5)= 105+30= 135

so now she has 7 pants and 6 shirts.

Answer:

[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]

They lie on the same horizontal line

Distance = 11 units

[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]

They do not lie on the same vertical or horizontal line

Step-by-step explanation:

Given

[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]

[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]

Required

Determine if the points lie on the same vertical or horizontal line

A point is represented as: [tex](x,y)\\[/tex]

Using the above illustration, we have:

[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]

The above have the same x values (0), hence they lie on the same horizontal line.

The distance between them is:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

[tex]d = \sqrt{(0-0)^2 + (-2 - 9)^2}[/tex]

[tex]d = \sqrt{0^2 + (-11)^2}[/tex]

[tex]d = \sqrt{0 + 121}[/tex]

[tex]d = \sqrt{121}[/tex]

[tex]d = 11[/tex]

The distance between them is 11 units

[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]

The above pair do not have the same x value and they do not have the same y value.

Hence, they do not lie on the same vertical or horizontal line

Answer:

A = 121 pi in^2

Step-by-step explanation:

The circumference is given by

C = 2 * pi*r

22 pi = 2 * pi *r

Divide each side by 2 pi

22 pi / (2 pi) = 2 pi r / (2pi)

11 = r

Now find the area

A = pi r^2

A = pi (11)^2

A = 121 pi in^2

Answer:

Answer:

Y = 60 degrees and X = 12

Step-by-step explanation:

x+3 and 15 are congruent so x+3 = 15, 12+3 = 15 therefore x = 12

y = 60 vertically opposite angles are equal. :D

Answer:

x= 12

y= 60

Step-by-step explanation:

to find x we need to know that lines DC and AB are parallel, so they have the same length (I don't know if that is why they have the same length, but I know they do lol)

So you can make this equation and solve:

15=x+3

-3     -3

12=x

THEN, to find y angle A and C are vertical angles, so they are congruent (this is the reason why they have the same measure lol)

So, y=60 degrees :)

Answer:

[tex]25x = 1250[/tex]

[tex]\frac{1250}{25}[/tex]

x=50

x has value 50

The solution to the equation is given by:

F. [tex]x = \frac{\sqrt{10} + 2}{5}[/tex]

It is given by:

[tex](5x - 2)^2 = 10[/tex]

First, we apply the square root to both sides to remove the square, hence:

[tex]\sqrt{(5x - 2)^2} = \sqrt{10}[/tex]

[tex]5x - 2 = \sqrt{10}[/tex]

Then, isolating x:

[tex]5x = \sqrt{10} + 2[/tex]

[tex]x = \frac{\sqrt{10} + 2}{5}[/tex]

Given by option F, which is the solution.

It is to be noted that the scatter plot that represent the above data is attached accordingly.

A scatter plot is a graph in which the data of two variables are displayed along two axes, and any association is revealed by the pattern of the resultant dots.

Slope-intercept form is y = mx + b

m is the gradient of the line, determined by calculating "change of y divided by change of x"

To compute for the gradient (m) we say:

(60 - 32)/(8-2)

= 28/6

m = 4.667

Next we calculate for b

The point on the graph where the line crosses the vertical line is known as the y-intercept, or b. (y-axis).

Put one of the graph's points, say (2, 32), and the amount of m you just computed into the slope-intercept form to calculate b.

That is:

32 = m(2) + b

Recall that m = 4.667

Hence 32 = 4.667 * 2 + b

32 = 6.667 + b

b = 32 - 6.667

b = 25.33

Given that we have the figures for m and b,
Recall that the function is: y = mx + b; and that

If x = 14 years, then

y = 4.667 * 14 + 25.33

y = 90.668

y ≈ 91 kg.

1) I would lean more toward false because most of the points aren't in a straight line

2) That is most likely true because the line of best fits appears to be hitting that point

3) That is false because point D is located on the line of best fit which means it isn't an outlier
