Step-by-step explanation:

The question says "20% of 45 ".

So, framing it , we get:-

[tex]\tt{\dfrac{20}{100}\times 45}[/tex]

So, solving it,

[tex]\tt{\dfrac{20\times 45}{100}}[/tex]

[tex]\tt{\dfrac{900}{100}}[/tex]

[tex]\tt{9}[/tex] is the answer.

Answer:

  (1, -5)

Step-by-step explanation:

Here, it is easy to check the offered choices. We find the first one works, so our check is short.

For (x, y) = (1, -5)

  3·1 +10·(-5) = 3 -50 = -47 . . . yes

  5·1 -7·(-5) = 5 +35 = 40 . . . yes

__

Both of the intercepts in the first equation are negative, so the line will form a triangle with the axes in the 3rd quadrant. The intercepts for the second equation are negative for y and positive for x, so the line forms a triangle with the axes in the 4th quadrant. The y-intercept for the first equation is -4.7; for the second equation, it is -40/7 = -5 5/7. This means the lines must cross in the 4th quadrant.

The only offered point in the 4th quadrant is (1, -5).

Answer:

  -22

Step-by-step explanation:

Put the value of x where x is and do the arithmetic.

  f(3) = -2(3)^2 -4 = -2·9 -4 = -18 -4

  f(3) = -22

Answer:

C

Step-by-step explanation:

c is parallel because the slopes are identical

Answer:

  16, 29, 7, 9, 36, 33, 24, 12

Step-by-step explanation:

The distance between two points on a number line is the magnitude of the difference between their coordinates. In general, that means you can subtract the coordinate of the left point from the coordinate of the right point to find the distance.

Here, the points are in alphabetical order on the number line, left-to-right, as are the letters in the segment names.  So you subtract the coordinate of the first point of the name from the coordinate of the last point in the name.

This is 8 simple subtraction problems.

a) D - B = -1 -(-17) = 16

b) E - A = 4 -(-25) = 29

c) F - E = 11 -4 = 7

d) I - G = 25 -16 = 9

e) H - C = 23 -(-13) = 36

f) G - B = 16 -(-17) = 33

g) F - C = 11 -(-13) = 24

h) C - A = -13 -(-25) = 12

_____

If you think of it as mileposts on a highway, it should be no surprise that the distance between milepost 4 and milepost 11 is 11 - 4 = 7 miles.

Answer: -3 because -7 +4 is equal to -3 and because im smart like that

Answer:

Smaller=x Larger=x+2

x+x+2=144

2x+2=144

2x+2-2=144-2

2x=142

2x/2=142/2

x=71

Smaller=71

Larger=73

Check: 71+73=144

Step-by-step explanation:

please mark me as the brainliest answer and please follow me for more answers to your questions.

Answer:

71 and 73

Step-by-step explanation:

First, set up an equation: let x be the smaller number, and let x+2 be the bigger one.

Then, since these two number's sum is 144, we can set up the equation x+(x+2) = 144.

Solve for x: 2x+2=144 -> 2x = 142 -> x = 71

As the smaller number is defined as x, we solved for the smaller number: 71. The bigger number is defined as x+2, so the bigger number is just going to be 2 more than the smaller number, which is 73.

Therefore, we arrive at our answers 71 and 73.

Let's see what to do buddy...

_________________________________

Step (1)

Suppose we want to find the sum of numbers from 1 to n.

To do this, we use the following method.

By writing the sum of numbers from 1 to n

, Then we write the sum of numbers n to 1 below it, see :

[tex]s = 1 + 2 + 3 + ... + n[/tex]

[tex]s = n + (n - 1) + (n - 2) + ... + 1 \\ [/tex]

Now we add the sentences of the above two phrases, peer to peer like this :

[tex]1 + n = n + 1 \\ [/tex]

[tex]2 + n - 1 = n + 1[/tex]

[tex]3 + n - 2 = n + 1[/tex]

And the others.....

So we have :

[tex]2s = ( n + 1) + (n + 1) + ... + (n + 1) \\ [/tex]

We had n numbers to sum so we have :

[tex]2s = n \times (n + 1)[/tex]

Divided the sides of the equation by 2

[tex]s = \frac{n \times (n + 1)}{2} \\ [/tex]

Remember this step I will use it again.

_________________________________

Step (2)

What does the linear sequence mean ?

The linear sequence is the sequence which any terms created by the sum of previous term with constant.

I name that constant value d.

According to above :

[tex]t(2) = t(1) + d[/tex]

And

[tex]t(3) = t(2) + d [/tex]

[tex]t(3) = t(1) + d + d[/tex]

[tex]t(3) = t(1) + 2d[/tex]

I have a question ;

[tex]3 - 1 = 2[/tex]

Is it correct ?

If it is correct we have :

[tex]t(3) = t(1) + (3 - 1)d[/tex]

WOW we found a thing ;

Put n instead of 3 :

[tex]t(n) = t(1) + (n - 1)d[/tex]

_________________________________

Step (3)

Stop right here.

Let's go to find the sum of the n first terms of the linear sequence.

Do you remember what did we do in step(1) ? Of course you do.

Let's do it again.

[tex]s = t(1) + t(2) + t(3) + ... + t(n) \\ [/tex]

[tex]s = t(n) + t(n - 1) + t(n - 2) + ... + t(2) + t(1) \\ [/tex]

According to the thing what we found in step(2) we have :

[tex]s = t(1) + ( \: t(1) + d \: ) + ( \: t(1) + 2d \: ) + ... + ( \: t(1) + (n - 1)d \: ) \\ [/tex]

[tex]s = ( \: t(1) + (n - 1)d \: ) + ( \: t(1) + (n - 2)d \: ) + ... + t(1) \\ [/tex]

Sum the two above equation's terms like this:

[tex]t(1) + t(1) + (n - 1)d = 2t(1) + (n - 1)d \\ [/tex]

And

[tex]t(1) + d +t(1) + (n - 2)d = 2t(1) + d(n - 2 + 1) = 2t(1) + (n - 1)d \\ [/tex]

And the others like this.

We had n terms so we sumed n terms.

So we have :

[tex]2s = n \times ( \: 2t(1) + (n - 1)d \: )[/tex]

Divided the sides of the equation by 2

[tex]s(n) = \frac{n}{2} \times ( \: 2t(1) + (n - 1)d \: ) \\ [/tex]

Answer:

All real numbers except 7

Step-by-step explanation:

Answer:

The answer is

[tex] \huge y = 3x + 21[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (−5, 6) and slope = 3

The equation of the line is

[tex]y - 6 = 3(x + 5) \\ y - 6 = 3x + 15 \\ y = 3x + 15 + 6[/tex]

We have the final answer as

[tex]y = 3x + 21[/tex]

Hope this helps you

Answer:

All three are correct.

Step-by-step explanation:

1x12 is 12, so #1 is correct.

2x6 is 12, so #2 is correct.

3x4 is 12, so #3 is correct.

Answer:

a = 3, b = -4

Step-by-step explanation:

You need to combine like terms in the expression. In the end, you get 3 - 4i. That's in the form of a + bi. So a = 3 and b = -4

Answer:

yavonee can read 25 pages in 50 minutes with the same rate.

Step-by-step explanation:

calcuate how may pages does yavonee read in 1 minute

14/28

= 1/2 or 0.5

0.5 * 50

= 25

In 50 minutes Yavonee can read 100 pages with a unit rate of 2 pages per minute.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Yavonee reads 14 pages in 28 mins.

∴ In 1 minute she reads (28/14) = 2 pages.

So, In 50 minutes she can read (2×50) = 100 pages.

Given function:

       f(x) = 2 - 5x

Table;

        x                        f(x)

        -2                         12

         -1                          7

          1                          -3

          2                        -8

The function is f(x) = 2 -5x

For;   x = -2;        f(x) = 2 - 5(-2)  = 12

                            f(x) = 2 - 5(-1) = 7

                            f(x) = 2 - 5(0) = 2

                            f(x) = 2 - 5(1) = -3

                            f(x) = 2 - 5(2) = -8

Answer:f(x) = 2 - 5(-2)  = 12

                           f(x) = 2 - 5(-1) = 7

                           f(x) = 2 - 5(0) = 2

                           f(x) = 2 - 5(1) = -3

                           f(x) = 2 - 5(2) = -8

The function f ( x ) = 2 − 5 x.

Plug in-  f ( 2 ) = 2 − 5x2

Simplify

Answer:

It is odd

Step-by-step explanation:

For example let's substitute 1 for x

f(x) = 4(1)+3

         4+3

f(x) = 7 this is odd

Let's substitute 2

f(x) = 4(2)+3

         8+3

f(x) = 11 this is odd

This means no matter what you substitute for x, it will be odd
