Answer:

  x ≈ -17.457  or  11.457

Step-by-step explanation:

The distance formula can help.

  d = √((x2 -x1)² +(y2 -y1)²)

Substituting given values, we have ...

  15 = √((x -(-3))² +(9 -5)²)

  225 = (x +3)² +16 . . . . . . . . square both sides

  209 = (x +3)² . . . . . . . . . . . subtract 16

  ±√209 = x +3 . . . . . . . . . take the square root

  -3 ± √209 = x . . . . . . . . subtract 3

  x ≈ -17.457  or  11.457

Answer:

see explanation

Step-by-step explanation:

The dot above the 5 indicates the 5 is repeating , that is

2.7555...

We require 2 equations with the repeating 5 placed after the decimal point.

let x = 2.7555,,, ( multiply both sides by 10 and 100 )

10x = 27.55... → (1)

100x = 275.55... → (2)

Subtract (1) from (2), thus eliminating the repeating 5

90x = 248 ( divide both sides by 90 )

x = [tex]\frac{248}{90}[/tex] = [tex]\frac{124}{45}[/tex]

Answer:

arithmetic sequence

Step-by-step explanation:

There is a common difference between consecutive terms , that is

d = 7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3

This indicates the sequence is arithmetic with common difference d = 3

Answer:

y= 4x -3

Step-by-step explanation:

1) add -8x at both members

8x - 2y - 8x = 6 - 8x

-2y =  -8x + 6

2) divide both members by -2

y = 4x -3

Answer:

2

Step-by-step explanation:

Slope = Change in y over change in x

Looking at the graph, as y goes up 4 x goes up 2

Thus, slope = 4/2 or 2

Answer: cost to buy 7.4 pounds of avocados from this store=$17.39

Step-by-step explanation:

Sale of avocados   per pound in the grocery= $2.35  

Sale of 7.4 pounds of avocados=  $2.35  x 7.4 pounds =$17.39

Therefore, the cost to buy 7.4 pounds of avocados from this store=$17.39

Answer:

Mean= Summation /number of terms

= 48/8

=6.

Median

To do this

arrange all terms from smallest to biggest

That is

2,4,4,5,7,8,9,9

The two middle numbers are

5 and 7.

To get the median

add both and divide by 2

5+7 = 12... 12/2 =6

Median=6

Mode.... This is the number that appears most

Mode = 4 and 9.(Bimodal) Both appear equally.

Range: Highest - Lowest

= 9-2 =7.

Answer:

mean = 6 median = 6 mode 9 and 4 range = 7

Step-by-step explanation:

mean = 2+4+4+5+7+8+9+9÷ 8 = 6

median = 5+7÷2

mode = 9 and 4

range = 9-2=7

Answer:

The sunflower is doing this because it is following the direction of the sun, which is a key factor in photosynthesis.

Step-by-step explanation:

Answer:

a sunflower bends down to East in morning because the sun rises in east. all flowers grows towards the light of the sun. during 12 noon sun is middle of east and west so its growing towards the light at straight way. during 4 o' clock in afternoon became sun goes down to west so the sunflower bends down to the light.

Answer:

I think u got yr question incomplete

there is no any equation

1.

a) metres to centimetres :

multiply length by 100

b) metres to millimetres:

multiply length by 1000

c) kilograms to grams:

multiply the mass value by 1000

d) litres to millilitres :

multiply volume by 1000

2.

a) 3 m = 3× 100 = 300 cm

b) 28 cm = 28 × 10 = 280 mm

c) 2.4 km = 2.4 × 1000

= 24 × 10^-1 × 10^3

= 24 × 10^2 =2400 m

d) 485 mm =485 / 10

= 485 / 10 ^1

= 485 × 10 ^-1

= 48.5 cm

e) 35 cm = 35 / 100

= 35 /10^2

= 35 × 10 ^ -2

= 0.35 m

f) 2.4 m = 2.4 / 1000

= 24 × 10 ^-1 / 10^3

= 24 × 10^-1 × 10 ^-3

= 24 × 10 ^ -4

= 0.0024 km

g) 2495 mm = 2495 /1000

= 2495 /10^ 3

= 2495 × 10 ^-3

=2.495 m

Answer:

68

Step-by-step explanation:

Measure of arc = Measure of corresponding central angle

Thus, if the measure of an arc = 68, then the measure of its central angle also = 68

Answer:

B

Step-by-step explanation:

Hi there!

We're given the measure of <AOC (the big angle) as 90°

and the measure of <BOC as 14° and the measure of <AOB as (3x+46)°

we want to find the value of what x is

because of angle addition postulate, m<AOC=m<BOC+m<AOB

so we can substitute our known values into that equation

90°=14°+3x°+46°

our goal is to isolate the variable of x onto one side

add 14 and 46 together

90°=3x°+60°

subtract 60° from both sides

30°=3x°

divide both sides by 3

10°=x

therefore B is your answer

Hope this helps!

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

Explanation:

Let a = 4 and b = 18 be the two known sides of the triangle.

Let c be the remaining side

We'll use a version of the triangle inequality theorem to set up the possible range of values for c.

The range of values for c is determined by the following

b-a < c < b+a

18-4 < c < 18+4

14 < c < 22

Telling us that the third side c is between 14 and 22, excluding both endpoints. This means c = 14 and c = 22 are not allowed. If either value were to happen, then the triangle becomes a single line instead. Try it out with slips of paper.

Because c = 14 is not allowed, we must go to the next whole number up. Therefore, c = 15 is the smallest possible length for the third side, when the third side is a whole number.

If the third side wasn't a whole number, then we could have something like c = 14.1 or c = 14.01 or c = 14.001 or c = 14.0001, and so on. We could steadily get closer and closer to 14, but never actually arrive to it. In short, there is no "smallest third side". This is likely why your teacher is focusing on the whole numbers so there is a smallest value of c possible.

Extra info: As you can probably guess, the largest side possible is c = 21, which is one less than 22. Like above, this is only possible if c is a whole number.

Answer:15

Step-by-step explanation: i got it right

Answer:

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

Step-by-step explanation:

Answer:

the surface area is 133cm.

7 x 7 is 49

7 x 6 is 42.

42 divided by 2 is 21.

21 x 4 is 84

So 84 + 49 is 133.

Given:

Segment MN has endpoints at M(-6, -3) and N(9,7).

Point Q lies on MN such that MQ:QN = 3:2.

To find:

The coordinates of point Q.

Solution:

Section formula: If a point divides of line segment whose end points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in m:n, then the coordinates of that points are:

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Segment MN has endpoints at M(-6, -3) and N(9,7) and Point Q lies on MN such that MQ:QN = 3:2. By using section formula, we get

[tex]Q=\left(\dfrac{3(9)+2(-6)}{3+2},\dfrac{3(7)+2(-3)}{3+2}\right)[/tex]

[tex]Q=\left(\dfrac{27-12}{5},\dfrac{21-6}{5}\right)[/tex]

[tex]Q=\left(\dfrac{15}{5},\dfrac{15}{5}\right)[/tex]

[tex]Q=\left(3,3\right)[/tex]

Therefore, the coordinates of point Q are (3,3).
