Can someone help me on this.

Answer:

MN=2.5cm

Step-by-step explanation:

4/2=6/3=8/4=k=2

MN=5/2=2.5cm

I'll do the first two to get you started

See the diagram below for the filled out answers.

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

Problem 1

You are correct in saying that 10 goes in the first box. This is from 2*5 = 10 when you apply the distributive property a*(b+c) = a*b+a*c.

For the next box, you'll have x go inside it. This is because we subtract 2x from both sides and then note how 3x-2x becomes x. This x is found on the right side of the third line.

For the last box, we have 9 go inside it. This is from subtracting 1 from both sides, so 10-1 becomes 9.

in that order

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

Problem 2

We add 2y to both sides so that 3y becomes 5y. Ie, 2y+3y = 5y

As a way to check the answer, note how 5y is on the left side of line 2.

Then we'll add 4 to both sides. So 6 updates to 6+4 = 10 on the right side. We type 10 in the second box.

The last step is to divide both sides by 2. The equation 5y = 10 solves to y = 2

Answer:

3.7018867924 × [tex]10^{-1}[/tex]

Step-by-step explanation:

First you want to find what these two numbers are, then you divide, then you put that answer in scientific notation.

1.728(109) = 188.352

4.8(106) = 508.80

Now we divide :

188.352 ÷ 508.80 = 0.37018867924

That's a crazy decimal, but luckily because of scientific notation we can make it look a lot simpler.

0.37018867924 =  3.7018867924 × [tex]10^{-1}[/tex]

This should be right. Please comment if you are confused and want more detail.

Answer:

'A' is true; theoretically, 50% of the data items reside between the first and third quartiles (40 and 67.5)

Step-by-step explanation:

Range is 84-28 which is 56

Median is 51

1.5 x Interquartile Range (IQR) = 1.5(67.5-40) which equals 41.25

Q1 is 40

Q1 - IQR = -1.25

Low outliers are below -1.25 - 41.25; there are not data items below -42

Answer:

f(3) = -4

Step-by-step explanation:

f(3) = f(2)*-1/2; Solve for f(2) first;

f(2) = f(1)*-1/2

f(2) = -16*-1/2

f(2) = 8;

Now get back to f(3);

f(3) = f(2)*-1/2

f(3) = 8*-1/2

f(3) = -4

Answer:

D. X=-3, y=4

Step-by-step explanation:

-2x+3y=18 equation 1

x=-y+1 equation 2

-2(-y+1)+3y=18 replace x value of equation 2 into equation 1

2y-2+3y=18

5y=20

y=4

solve for x by replacing y value into either equation.

x=-y+1

x=-4+1

x=-3

Answer:

C

Step-by-step explanation:

The radius is 4 making the diameter 16 you need the other side since in half so that leaves you with answer C...16[tex]\pi yd^2[/tex]

The average rate of change of the function over the interval [1,3] will be around 45 which is nearest an option to 42 so option (C) will be correct.

The link between lines and points is described by a graph, which is a diagrammatic representation of a network.

A graph consists of various points and the separation between two of them. Neither the length of the lines nor the placement of the points matters. Each component of a graph has a name, known as a node.

For example to draw the equation y = 2x +9 this will draw a straight line in the coordinate geometry.

The rate of change is given by dy/dx

The average rate of change can be given as (difference in y coordinate)/(difference in x coordinate)

Average rate of change = ( 102 - 12 )/(3 - 1 ) = 45 which is nearest to option (C) hence it will be correct.

Step-by-step explanation:

Answer:

Step-by-step explanation:

multiply the first equation by 2 in order to be able to cancel out the -4z and the 2x

4x-30y=-20

-4x+5y=-30

50y+5y = -20+(-30)

For the case of a line through

we have

Using the point

(

)

we can write the equation of the line in point slope form as:

y

−

7

=

m

(

x

−

2

)

where the slope

m

=

11

.

That is:

y

−

7

=

11

(

x

−

)

To get point intercept form, first expand the right hand side so...

y

−

7

=

11

x

−

(

11

⋅

)

=

11

x

−

Then add

7

to both sides to get:

y

=

11

x

−

=

11

x

(

This is point intercept (

x

) form with slope

m

=

and intercept

=
