Which of the following inequalities matches the graph

Answers
-6x + y < 3
6x - y < -3
The correct inequality is not listed
6x + y < 3

Answer:

8 pounds

Step-by-step explanation:

x represents the starting amount

5 = 3x/8 + x/4

40 = 3x + 2x     multiply both sides by LCD, 8

40 = 5x

x=8

Answers:

b)  92100 decimeters

c)   6650 decaliters

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

Work Shown for part b)

1 decameter = 10 meters

1 decimeter = 1/10 of a meter

10 decimeters = 1 meter .... multiply both sides by 10

100 decimeters = 10 meters ... multiply both sides by 10

100 decimeter = 1 decameter

921*(100 decimeter) = 921*(1 decameter)

92100 decimeters = 921 decameters

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

Work Shown for part c)

We could follow the same idea as part b). I'm going to use another approach as shown in the diagram below. This conversion method is known as the railroad tracks method in some math textbooks.

Each column represents two things that are equivalent to one another. For example, 1 kiloliter is the same as 1000 liters. So each column, when you divide top over bottom, represents the value 1.

Notice the unit cancelations as shown by the color coding. The goal is to have every unit cancel except for the decaliters unit which is what we want to end up with ultimately.

Once you have the railroad tracks set up, you multiply straight across.

Along the top, we have 66.5*1000*1 = 66500

Along the bottom we have 1*10 = 10

Divide those results: 66500/10 = 6650

So 66.5 kiloliters converts to 6650 decaliters

Answer:

1) 92100 dm

2) 6650 decalitres

Replace x with 180:

540/10 =

54

Answer : 54

Answer:

54

Step-by-step explanation:

x = 18

Evaluate:

3 x / 10

put the value of x

3 × 180 / 10

540 / 10

Answer:

x^2

Step-by-step explanation:

all the numbers are square roots so n square is the nth term.

2^2= 4

3^2=9

4^2=16

5^2=25

6^2=36

Answer:

[tex] {n}^{2} [/tex]

Step-by-step explanation:

Drawing number into triangular dot pattern and making a square (with same numbers of dots in rows and columns) will give a square number. Similarly, 16 = 42 = 32 + (3 + 3 + 1), 25 = 52 = 42 + (4 + 4 + 1) and so on.

Answer:

20

Step-by-step explanation:

We know that the diagonals are bisected, which means

2x+4 = 6x-8

Subtract 2x from each side

2x+4-2x = 6x-8-2x

4 = 4x -8

Add 8 to each side

4+8 = 4x-8+8

12 = 4x

Divide by 4

12/4 = 4x/4

3 =x

We want to know CF = DB = 2x+4 + 6x -8

CF = 8x-4

     = 8(3) -4

    = 24-4

   = 20

Answer:

$2.20 per kilogram

Step-by-step explanation:

Take the total cost and divide by the number of kilograms

15.40/ 7

2.20

$2.20 per kilogram

Answer:

Step-by-step explanation:

I am not sure if this is corect but you need to devide 7 by 15.40

and that is my best estimate

Step-by-step explanation:

Solve the equation for inverse and cross multiply.

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

Explanation:

Draw a vertical line through 5 on the x axis. This represents the equation x = 5. Notice that we intersect the blue line at (5,-1) which tells us that f(5) = -1. There's a closed point here, meaning that the point is included. This is in contrast to the open hole at (5,3) which is not part of the function. So be careful not to say that f(5) = 3 because that's not the case.

Answer:

i think it's f(5) - a wild guess

Step-by-step explanation:

Answer:

1 = y=-2x

2= y= -1/2x-1

3= y= 1/2x+1

4= y-3x+2

Graph 2: [tex]y=\frac{-1}{2} x+1[/tex]

Graph 3: [tex]y=\frac{1}{2} +1[/tex]

Answer:

a4 = 123

Step-by-step explanation:

Here, we want to find the value of the 4th term

we simply have n as 4

substituting this, we have;

a4 = (a3)^2 + 2

But a^3 = (a2)^2 + 2 and

so we have ;

a4 = [(a2)^2 + 2]^2 + 2

But a2 = (a1)^2 + 2

a4 = {[(a1)^2 + 2)]^2 + 2}^2 + 2

Now, substitute the value of a1

a4 = (1)^2 + 2)^2 + 2)^2 + 2

a4 = (1 + 2)^2 + 2)^2 + 2

a4 = (3^2 + 2)^2 + 2

a4 = 11^2 + 2

a4 = 121 + 2

a4 = 123

Answer:

p > 16/5

Step-by-step explanation:

-5p<-16

Divide each side by =5, remembering to flip the inequality

-5p/-5 > -16/5

p > 16/5

There is an open circle at 16/5 and the lines goes to the right

Answer:

f(- 3) = 18

Step-by-step explanation:

Answer:

1/2, 50%

Step-by-step explanation:

A cube has six sides. The probability of landing on a number less than four is 3/6 because there are 3 positive numbers less than 4. 3/6=1/2=50%

Answer:

x=104

Step-by-step explanation:

Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)

10.5 = 1/2( x-83)

Multiply each side by 2

2* 10.5 = 2*1/2( x-83)

21 = x-83

Add 83 to each side

21+83 = x-83+83

104 =x

25000 / 500 = 50 pounds.

Answer:

50

Step-by-step explanation:

25,000 / 500 = 50

Answer: 10%

Step-by-step explanation: R20 = 100

Therefore R1 = 100%÷ R20 = 5%. The difference between R22 and R20 is R2, therefore the increase in % is R2×5%=10%.

Answer:

+10%

Answer:

3

Step-by-step explanation:

fractions are division, so if you divide the numerator by the denominator you'll always get the mixed number / whole number

so 3/4 is equal to 3 divided by 4

15 divided by 5 is 3, because 3 x 5 = 15
