Answer:

[tex]a) 8y = 32.\\b)14-2y = 6.[/tex]

[tex]the \: right \: expression \: for \\ 3 \: is \: less \: than \: y \: is \: less \: than \: 7 \: is \\ 3 < y < 7. \\ then \\ y \: can \: be \: any \: value \: form \: (4 \: to \: 6). \\ so \: if \: y = 4. \\ then \\ 8y = 8 \times 4= 32. \\ and \\ 14 - 2y = 14 - 2 \times 4 = 6.[/tex]

The maximum and minimum value of the expressions are -

1 - 8y              Max [1] = 48              Min [1] = 32

2 - 14 - 2y           Max [2] = 6                  Min [2] = 2

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given is that 3 is less than y is less then 7.

We can write the inequality -

3 < y < 7

Expression 1 : 8y

Maximum value of the expression = Max [1] = 48

Minimum value of the expression = Min [1] = 32

Expression 1 : 14 - 2y

Maximum value of the expression = Max [2] = 14 - 2 x 4 = 14 - 8 = 6

Minimum value of the expression = Min [2] = 14 - 2 x 6 = 14 - 12 = 2

Therefore, the maximum and minimum value of the expressions are -

1 - 8y              Max [1] = 48              Min [1] = 32

2 - 14 - 2y           Max [2] = 6                  Min [2] = 2

Answer:

you know 2 sides are the same on an a silly triangle.. I mean isosceles.. so the hypotenuse will be longer but the other two sides are the same

use [tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]  ( Pythagoras theorem )

Step-by-step explanation:

[tex]4^{2}[/tex] = [tex]A^{2}[/tex] +[tex]A^{2}[/tex]  ( b/c the side are the same length the can both be called A )

16 = 2[tex]A^{2}[/tex]

Answer:

80

Step-by-step explanation:

Mean simply means the average. To calculate the average of all these numbers, add them all up together and divide that number by how many numbers you added.

A simple equation you can use is:

[tex]\frac{the sum of the terms}{the number of terms}[/tex]

To calculate the mean of the set : 0,100,100,100,100​

= 0 + 100 + 100 + 100 + 100

= 400 / 5

= 80

The mean of the set is 80.

The cost of an apple was 0.62 cents.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

An equation says that two things are equal.

For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given that, Bill bought 5 apples Mary bought 2 apples and spent 1.86 for strawberries. both the spent equal amounts, we need to write and solve the equation for the price of apples,

Let the cost of 1 apple = A

Bill bought = 5A apples

Mary bought=2A + 1.86

5A = 2A + 1.86

3A = 1.86

A = 1.86/3

A = 0.62 cents

Hence, the cost of an apple was 0.62 cents.

Answer:

After 5 hours.

35 bacteria cells.

Step-by-step explanation:

Andy’s population is represented by [tex]B=6x+5.[/tex]

Samantha’s population is represented by [tex]B=2^x+3[/tex]

Where B represents the total population given the number of hours x.

We want to find at what hour will their population be the same. We are told to use graphing technology.

Graphing them, we will get the graphs below.

Graphically, their population will be the same where the two graphs intersect.

So, we can see that they intersect at (5, 35).

Therefore, after 5 hours, the total number of bacteria cells for both experiments will be the same.

And the total number of bacteria at that time will be 35 bacteria cell.

√2 , 4^1/3 , 3^1/4

Find the LCM of 2, 3 , 4= 12

i ) √2 =2^1/2 = 2^6/12=(2^6)^1/12

= (64)^1/12

ii ) 4^1/3 = 4^4/12 = (4^4)^1/12

= (256)1/12

iii )3^1/4 = 3^3/12 = ( 3³ )^1/12

Answer:

RS=6

ST=11

Step-by-step explanation:

answer is above

The value of x is 7 and the measure of the line segment RS is 6 units, ST = 11 units, and RT = 11 units

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Point S is between points R and T on RT.

RS = 2x - 8

ST = 3x - 10

RT = 17

From the above information:

RT = RS + ST

17 = 2x - 8 + 3x - 10

17 = 5x - 18

35 = 5x

x = 35/5

x = 7

RS = 2x - 8 = 2(7) - 8 = 6 units

ST = 3x - 10 = 3(7) - 10 = 11 units

RT = 17 units

Thus, the value of x is 7 and the measure of the line segment RS is 6 units, ST = 11 units, and RT = 11 units.

Answer: x=5

Step-by-step explanation:

3x appears two times and so does 2x +2. That created the equation 3x + 3x + 2x + 2 + 2x + 2=54. Combine like terms. You get 10x +4=54. Then you solve. Inverse operation: You subtract 4 from 54. Which is 50, then divide by 10. X=5

The value of the x for the given rectangle is 5 units.

The whole distance that a rectangle's boundaries, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the sum of its four sides.

Given, The perimeter of the rectangle below is 54 units.

Also given the length of the rectangle = 3x

and the width of rectangle = 2x + 2

Since, Perimeter of rectangle = 2 *( length + width)

Perimeter of rectangle = 2 * (3x + 2x + 2)

Since we have a perimeter

54 = 2 *(5 x + 2)

5x + 2 = 27

5x = 25

x = 5

Therefore, For the given rectangle, the value of x is 5 units.

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + 6y = - 18 ( subtract 3x from both sides )

6y = - 3x - 18 ( divide all terms by 6 )

y = - [tex]\frac{1}{2}[/tex] x - 3 ← in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2

Slope of the line perpendicular to given line 3x + 6y = –18 is 2

The slope intercept of a line is given : y = m x+ c

y is y coordinate, x is x coordinate, m is the slope of the line

c is y- intercept of the line

If given that the slope of two lines are m₁ and m₂ then these lines are perpendicular, if the product of their slopes is -1 or  m₁ *m₂ = -1

Given line is 3x + 6y = –18

Subtract 3x from both sides

⇒ 3x +6y -3x = -3x-18

⇒  6y = -3x-18

⇒ y =(-3/6)x -18 /6 = (-1/2) x -3

comparing it with slope intercept , slope = -1/2

let the slope of line perpendicular to given line is m

then m.(-1/2) = -1

   ⇒ m = 2

∴Slope of the line perpendicular to given line is 2
