What is the graph of the inequality

Answer:

2 pieces

Step-by-step explanation:

Julie wants to cut 1 and a quarter yard long pieces of a 3 yard string.

1 and a quarter yard =  [tex]1\frac{1}{4}[/tex] yards =  [tex]\frac{5}{4}[/tex] yards

= 1.25 yards

The total length of a piece of string = 3 yards

Julie can cut the number of pieces of 1.25 yards = [tex]\frac{3}{1.25}[/tex]

                                                                                 = 2.4 pieces

She can cut 2 pieces of 1.25 yard = 1.25 × 2 = 2.5 yard

3 yard - 2.5 yard = 0.5 yard would be leftover.

(2n - 9) - 5(-2.4n + 4) =

The first set of parentheses is unnecessary, so we just drop them.

= 2n - 9 - 5(-2.4n + 4)

Now we distribute -5 by the second set of parentheses. Each term in the parentehses is multiplied by -5.

= 2n - 9 + 12n - 20

Now we combine like terms.

= 2n + 12n - 9 - 20

= 14n - 29

Answer:

296

Step-by-step explanation:

111/3 = 37

37 * 8 = 296

The inequality is

[tex]-32> -5+9x[/tex]

We need to isolate x and for that first we need to get rid of 5 by adding 5 to both sides.

[tex]-32+5 +-5+9x+5\\-27>9x\\[/tex]

Now we need to get rid of 9 and for that we divide both sides by 9 .That is

[tex]-\frac{27}{9}>\frac{9x}{9}[/tex]

[tex]-3>x[/tex]

[tex]x<-3[/tex]

Start with expressions in blue boxes:

1st column) [tex]36x+9;[/tex]

2nd column) [tex]9(4x-1)=36x-9;[/tex]

3rd column) [tex](4\cdot 9x)+(4\cdot 2)=36x+8.[/tex]

You have 6 expressions. Consider all them:

1. [tex]36x+8[/tex] - 3rd column;

2. [tex](9\cdot 4x)+(9\cdot 1)=36x+9[/tex] - 1st column;

3. [tex](3\cdot 12x)-(3\cdot 3)=36x-9[/tex] - 2nd column;

4. [tex]9(4x+1)=36x+9[/tex] - 1st column;

5. [tex]36x-9[/tex] - 2nd column;

6. [tex]4(9x+2)=36x+8[/tex] - 3rd column.

Answer:

The equivalent expressions are:

[tex]36x + 9=(9\cdot 4x) + (9\cdot 1)=9(4x + 1)[/tex]

[tex]9(4x-1)=36x-9=(3\cdot 12x)-(3\cdot 3)[/tex]

[tex](4\cdot 9x)+(4\cdot 2)=4(9x+2)=36x+8[/tex]

Step-by-step explanation:

Consider the provided expressions.

[tex]36x + 9[/tex]

The expression [tex]36x + 9[/tex] can be written as:

[tex]36x + 9=(9\cdot 4x) + (9\cdot 1)[/tex]

[tex]36x + 9=(9\cdot 4x) + (9\cdot 1)=9(4x + 1)[/tex]

Consider the expression [tex]9(4x-1)[/tex]

The expression [tex]9(4x-1)[/tex] can be written as:

[tex]9(4x-1)=36x-9[/tex]

Take 3 common.

[tex]9(4x-1)=36x-9=(3\cdot 12x)-(3\cdot 3)[/tex]

Consider the expression [tex](4\cdot 9x)+(4\cdot 2)[/tex]

The expression [tex](4\cdot 9x)+(4\cdot 2)[/tex] can be written as:

Take out 4 common

[tex](4\cdot 9x)+(4\cdot 2)=4(9x+2)[/tex]

Open the parentheses.

[tex](4\cdot 9x)+(4\cdot 2)=4(9x+2)=36x+8[/tex]

[tex]\left(\dfrac{3}{\sqrt5}\right)\left(\dfrac{4}{\sqrt3}\right)=\dfrac{3\cdot4}{\sqrt5\cdot\sqrt3}=\dfrac{12}{\sqrt{5\cdot3}}=\dfrac{12}{\sqrt{15}}\\\\=\dfrac{12\cdot\sqrt{15}}{\sqrt{15}\cdot\sqrt{15}}=\dfrac{12\sqrt{15}}{15}=\dfrac{12\sqrt{15}:3}{15:3}=\dfrac{4\sqrt{15}}{5}[/tex]

The answer is:  " 23 " .

    →  The fourth number in the sequence is:  " 23 " .

_____________________________________

Explanation:

To solve:

 " x + (x + 1) + (x + 2) + (x + 3)  + (x + 4) = 110 " ;

in which:

 "x" = The first number in these sequence;

 "(x + 1 )" = the second number in the sequence;

 "(x + 2)" = the third number in the sequence;

 "(x + 3)" = the fourth number in the sequence;

 "(x + 4)" = the fifth number in the sequence;

_____________________________________

Solve for the "fourth number in the sequence" ; or:  "(x + 3)" ;

_____________________________________

Given:  " x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 110 " ;

                     ↔   " x + x + 1 + x + 2 + x + 3 + x + 4 = 110 " ;

→  Solve for "x" ;  

→  then,  solve for "(x + 3)" ;  

     →  which is the fourth number in this sequence;

_____________________________________

→  " x + x + 1 + x + 2 + x + 3 + x + 4= 110 " ;

      "5x + 1 + 2 + 3 + 4= 110 " ;

      " 5x + 10 =  110 " ;

Solve for "x" :

     Subtract "10" from EACH SIDE of the equation; as follows:

      " 5x + 10 - 10 =  110 - 10 " ;

 to get :

      "  5x = 100 " ;

Now, divide EACH SIDE of the equation by "5" ;

to isolate "x" on one side of the equation; & to solve for "x" ;  as follows:

         5x / 5  = 100 / 5 ;

to get:

         "  x  = 20 "  .

_____________________________________

Now, to find the fourth number in the sequence:

 →  " (x + 3) " ;

→  Substitute "20" for "x" ;

    " x + 3 = 20 + 3 = 23" ;

_____________________________________

The answer is:  " 23 " .

The fourth number in the sequence is:  " 23 " .

_____________________________________

Let us check our work:

If there are five "5" numbers in the sequence, and "23" is the "fourth number" , then:  "24" is the "fifth number" .

As such:  "22" is the "third number" ;  "21" is the "second number" ; and "20" is the "first number" .  Is this consistent with:  "x = 20" as the "first number" ?  Yes!

Thus,  "20 + 21 + 22 + 23 + 25 = ?  110 ?  ? ;

→  20 + 21 = 41 ;

→  41 + 22 = 63 ;

→  63 + 23 = 86 ;

→  86 + 24 = 110 .    Yes!

Step-by-step explanation:

Dived the price by the number of ounces and that should be your answer to the questions .

150 can't go into 180 equally, so the answer is 1.2

The distance formula is given by:

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }[/tex]

We are given two points A and B as

A(1,1) and

B(7,-7)

so we have ,

x1 = 1 , y1=1

x2= 7 and y2=-7

Plugging these in the formula we have:

[tex]d=\sqrt{(7-1)^{2}+(-7-1)^{2} }[/tex]

d=√(36+64)

d=√100

d=10

Answer: The distance between A(1,1) and B(7,-7) is 10

Answer:

d=10 units

Step-by-step explanation:

Hello.

Step 1

the formula of the distance between two points is based on the Pythagorean theorem, which states that in a rectangle :

[tex]side^{2} +side^{2}=hypotenuse^{2}\\[/tex]

Now, suppose we have two points P1(X1,Y1) and P2(X2,Y2), the distance between the two points will be the hypotenuse of our triangle, the difference in x will be the adjacent leg, and the difference in coordinates in y will be our opposite leg.

adjacent side =X2-X1

opposite side=Y2-Y1

hypotenuse=distance between P1 and P2

replacing

[tex]adjacent\ leg^{2} +opposite\ leg^{2}=hypotenuse^{2}\\(x_{2}-x_{1}) ^{2} +(y_{2}-y_{1})^{2}=(distance between\ P1\ and\ P2)^{2}\\ distance between\ P1\ and\ P2=\sqrt{(x_{2}-x_{1}) ^{2} +(y_{2}-y_{1})^{2}} \\\\[/tex]

we take only the positive root because it is a distance, a negative distance makes no sense

Step 2

find the distance between A(1,1) and B (7,-7) using the formula

Let

P1=A(1,1)

P2=B(7,-7)

put the values into the formula

[tex]d=\sqrt{(x_{2}-x_{1}) ^{2} +(y_{2}-y_{1})^{2}} \\let\\\\x_{1}=1,y_{1}=1,x_{2}=7,y_{2}=-7\\d=\sqrt{(7-1) ^{2} +(-7-(1))^{2}}\\d=\sqrt{(6) ^{2} +(-8)^{2}}\\d=\sqrt{36 +64}\\d=\sqrt{100}\\ d=10[/tex]

d=10 units

Answer:

1968

Step-by-step explanation:

I use the following method when it comes about products of big numbers

I grab the longer and put on the first line, below I put the smallest number.

492

x 4

Now, it is time to distribute the product, term by term, remember that when performing a product, if the result is greater or equal than 10, you need to carry a number for the following product.

      492

        x 4

--------------------

   19    6    8

(end) (c3) (nc)

nc means: not carrying anything since 4x2=8 and 8 <10

c3 means: carrying 3 since 4x9= 32 and 32 >10

end means: put the whole number and sum it what you were carrying. 4*4+3=19

The product 492*4=1968

The product of 4 multiplied by 492 equals 1968. To find this, we used a step-by-step approach using basic multiplication and the distributive property.

To determine the product of 4 multiplied by 492, you can execute the following steps:

Therefore, 4 × 492 = 1968.

The wholesale price of the home audio system is = $264

The electronics store had marked up the price of the system by = 60%

So, the additional price becomes= [tex]\frac{60}{100}*264[/tex] = $158.40

Total price of the audio system now becomes = 264+158.40 = $422.40

As Lori was paid commission of = 15% on 422.40, so her commission becomes = [tex]\frac{15}{100}*422.40[/tex]

Step-by-step explanation:

I am doing a unit test on it.

CE is equal to 58 units.

To find the length of CE, we'll use the fact that D is the midpoint of CE. The midpoint of a line segment divides it into two equal parts.

If CD is one part and DE is the other, then we can set up an equation:

CD=DE

9X−7=3X+17

Now, solve for X:

6X=24

X=4

Now that we have the value of X, substitute it back into either CD or DE to find the length of each part:

CD=9X−7=9(4) −7=36−7=29

DE=3X+17=3(4) +17=12+17=29

Now, since D is the midpoint, CD and DE are equal.

CD=DE=29

Finally, CE, the total length, is the sum of CD and DE:

CE=CD+DE=29+29=58

So, CE is indeed 58

Hello!

I was going to try to use the slope formula, and solve for the y-intercept, but the given graph is hard to distinguish accurate ordered pairs. So, we will find the equation with the graph instead.

Looking at the graph, we can see that the y-intercept is negative. Also, we can also determine that each square represents one unit. So, the y-intercept has to be -3/2 or -1.5. That removes the choices A and C because the y-intercept is in between the values of -1 and -2.

Secondly, the graph has a positive slope. Why? When the x-values increase, the y-values increase. Also, when the x-values decrease, the y-values also decrease. This tells us that the graph has a positive slope (this doesn't remove any choices, but it helps to distinguish which graph has a positive or negative slope).

Finally, we know that if the slope is greater than one, then it is steeper (m > 1). But, if it's less than one, then it becomes less steep (0 < m < 1). Looking at the graph, the graph looks relatively steep (graphing the equations y = 5/7 x - 3/2 and y = 7/5x - 3/2 can help you see the differences between them).

Therefore, the equation of the line given by the graph is choice D, y = 7/5 x − 3/2.

The equation of the line given by the graph is y = 5/7 x - 2/3 (Option A).

The equation of the line given by the graph is y = 5/7 x - 2/3 (Option A).

To determine the equation, we look at the slope and y-intercept of the line. The slope of the line can be determined by comparing the change in y-coordinates to the change in x-coordinates between any two points on the line. In this case, the slope is 5/7. The y-intercept is the value of y when x = 0, which is -2/3 in this case.

Therefore, the equation of the line is y = 5/7 x - 2/3.

Answer:

It is 8 3 pointers and 13 2 pointers

Step-by-step explanation:

8 x 3 = 24

13 x 2 = 26

24 + 26 = 50

The bulldogs made 13 2-pt shots and 8 3-pt shots.

Let's assume that the bulldogs made x 2-pt shots and y 3-pt shots. Since each 2-pt shot is worth 2 points and each 3-pt shot is worth 3 points, we can set up the following equations: 2x + 3y = 50 (equation 1) and x + y = 21 (equation 2). To solve this system of equations, we can multiply equation 2 by 2 to get 2x + 2y = 42, and then subtract equation 1 from it. This gives us y = 8. Substituting y = 8 into equation 2, we get x + 8 = 21, which means x = 13. Therefore, the bulldogs made 13 2-pt shots and 8 3-pt shots.
