Answer:

[tex]3x+5[/tex]

Step-by-step explanation:

Simplify using the distributive property:

[tex]2*(2.5x)+2*(2)-(2x-1)\\\\5x+4-(2x-1)[/tex]

Simplify parentheses using the distributive property (the negative sign can be seen as -1):

[tex]5x+4-1*(2x)-1*(-1)\\\\5x+4-2x+1[/tex]

Combine like terms:

[tex](5x-2x)+(4+1)\\\\3x+5[/tex]

This cannot be simplified further.

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

First we need two points of the table :

I choose a = ( 0 , 3 ) and b = ( 2 , 0 ) .

_________________________________

Step (2)

To find the slope of linear functions using two points, we use the following equation :

[tex]slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]

Where a and b are two points of the function.

_________________________________

Step (3)

Now just need to put the coordinates of the points which we chose.

a = ( 0 , 3 ) °•°•°•°•°•°•° b = ( 2 , 0 )

[tex]slope = \frac{0 - 3}{2 - 0} \\ [/tex]

[tex]slope = - \frac{3}{2} \\ [/tex]

And we're done.

Thanks for watching buddy good luck.

Answer:

C. x²+3x-28

Step-by-step explanation:

f(x) = x +7

g(x) = x -4

f(x) · g(x) = (x-4)(x+7)

              = x²+7x-4x-28

              = x²+3x-28

Answer:

B multiply -6 and 3

The midpoint of AB is (-5, 1).

To find the midpoint of a line segment AB, we average the x-coordinates of the two endpoints and the y-coordinates of the two endpoints.

Given that A has coordinates (-3, 8) and B has coordinates (-7, -6), we calculate the midpoint as follows:

x-coordinate of midpoint = (x-coordinate of A + x-coordinate of B) / 2

                     = (-3 + -7) / 2

                     = -10 / 2

                     = -5

y-coordinate of midpoint = (y-coordinate of A + y-coordinate of B) / 2

                     = (8 + -6) / 2

                     = 2 / 2

                     = 1

Therefore, the midpoint of AB is (-5, 1), where -5 is the x-coordinate and 1 is the y-coordinate. This means that the midpoint is equidistant from points A and B, dividing the line segment AB into two equal parts.

Step-by-step explanation:

Answer:

The answer is 62

Step-by-step explanation:

the ratio given can be written as [tex]\frac{20}{11}[/tex].

first, we need to solve for how many boys received if the girls received 40.

let's write a new ratio to show this.

[tex]\frac{20}{11} = \frac{40}{x}[/tex]

notice how i was able to equal them to each other. this is because they represent the same rate.

to solve for x, cross multiply.

[tex]20x= 440\\[/tex]

now solve.

[tex]x=22[/tex]

the 22 represents how many boys will receive if the girls receive 40.

the question is asking how many will be given out all together. this implies that we should add 40 and 22.

[tex]40+22= 62[/tex]

Correct answer's the top one

Step-by-step explanation:

Think of powers of 10. Each power is 10 times larger or smaller than the last one. So in this instance, the bacterium has a diameter of 10^-6 which is 1 millionth. And then there's the virus, which has a diameter of 10^-7 which is 1 ten millionth. So basically, take 10^-7 and times that by 10. This gives you 10^-6, which can only mean that the bacterium is 10 times bigger than the virus, which is the answer on top.

Answer:

-313

Step-by-step explanation:

a1=2; d=-5

a64=2-5(64-1)=-313

The 64th term of the arithmetic sequence 2, -3, -8 ... will be -313.

What is Arithmetic sequence?

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

Given that;

The arithmetic sequence;

⇒ 2 , -3 , -8 ...

Now,

The general equation for nth term of the arithmetic sequence is,

[tex]T_{n} = a + (n - 1) d[/tex]

Where, The term 'a' represent the first term.

And, 'd' represent the difference between each consecutive numbers.

Here, In the arithmetic sequence 2 , -3, -8;

The first term = 2

The difference = -3 - (2) = - 5

So, To find the 64th term of the arithmetic sequence, we can substitute

n = 64 and a = 2 and d = -5 in above formula as;

[tex]T_{n} = a + (n - 1) d[/tex]

[tex]T_{64} = 2 + (64 - 1) (-5)[/tex]

[tex]T_{64} = 2 + (63 * -5)[/tex]

[tex]T_{64} = 2 - 315[/tex]

[tex]T_{64} = -313[/tex]

Thus, The 64th term of the arithmetic sequence 2, -3, -8 ... will be -313.

Step-by-step explanation:

Answer:

[tex] \huge y = \frac{1}{4} [/tex]

Step-by-step explanation:

[tex]7(1 - y) = -3(y-2)[/tex]

Expand the terms in the bracket

That's

[tex]7 - 7y = - 3y + 6[/tex]

Add 3y to both sides of the equation

[tex]7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6[/tex]

Subtract 7 from both sides by the equation

[tex]7 - 7 - 4y = 6 - 7 \\ - 4y = - 1[/tex]

Divide both sides by - 4

[tex] \frac{ - 4y}{ - 4} = \frac{ - 1}{ - 4} \\ [/tex]

We have the final answer as

Answer: it 5 feet/yard

Step-by-step explanation:

The average yearly growth rate the tree is 5 feet per year.

Rate is a measurement to determine the change in one quantity with respect to another quantity.

Given that,

Height of tree = 18 feet

Also, the tree grew in next 3 ¹/₂ years,

Since the tree grew to final height of 35 ¹/₂ or 71/2 feet.

The increased height of the tree = 71/2 - 18 = 35/2

To find the average growth rate of the height of the tree,

Use ratio method,

In 3 ¹/₂ years = 35/2 feet,

In 7/2 years = 35/2 feet,

in 1 year = 5 feet

The average growth rate of the height of the tree is  5 feet per year.

answer:

the question is confusing but the answer is 2010

step-by-step explanation:

because in the year 2000 it was

260

then increased by

60

over 5 years making the next class

320

then in 2010 it was

400

and 320 + what is 400?

80

so the answer is:

2010

In the year 2010 the high school graduating class experience the greatest experience of change.

Finding the difference between two numbers is done using the subtraction technique. The size of a group of things decreases if any of the objects are removed.

For instance, at your birthday celebration, you purchased 9 cupcakes, of which your friends consumed 7. There are only 2 cupcakes remaining for you now. Nine minus seven equals two, which may be represented as the subtraction expression 9 - 7 = 2. (9 - 7) = 2 is the result of subtracting 7 from 9.

According to the question, the given values are :

There are 260 people in the graduating class in 2000, then it increased by 60.

5 years later the people class in the class was 320.

Then in the year 2010, it was 400.

So, the difference between 400 and 320 is 80.

Hence, this concludes that the greatest change will occur in 2010.

Answer:

20:1

Step-by-step explanation:

It is given that,

Input voltage = 260 volt

Output voltage = 13 volt

We need to find the ratio of the number of input wire coils to output wire coils on the transformer.​

For a step-down transformer,

[tex]\dfrac{V_i}{V_o}=\dfrac{N_P}{N_S}\\\\\dfrac{N_P}{N_S}=\dfrac{260}{13}\\\\=\dfrac{20}{1}[/tex]
