The answer is B

Step-by-step explanation:

All they did was switch the numbers and if you use distribution it will be equal.

Answer:

Option B,C and E are solution to given inequality [tex]y - 3x < -8[/tex]

Step-by-step explanation:

We need to check which ordered pairs from given options satisfy the inequality [tex]y - 3x < -8[/tex]

Ordered pairs are solutions to inequality if they satisfy the inequality

Checking each options by pitting values of x and y in given inequality

A ) (1, -5)

[tex]-5-3(1)<-8\\-5-3<-8\\-8 < -8 \ (incorrect)[/tex]

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

B) (-3, - 2)

[tex]-2-3(-3) < -8\\-2-9<-8\\-11 < -8 (true)[/tex]

So, this ordered pair is solution of inequality as it satisfies the inequality.

C) (0, -9)

[tex]-9-3(0)<-8\\-9-0<-8\\-9<-8 \ (true)[/tex]

So, this ordered pair is solution of inequality as it satisfies the inequality.

D) (2, -1)

[tex]-1-3(2)<-8\\-1-6<-8\\-7<-8 \ (false)[/tex]

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

E) (5, 4)​​​

[tex]4-3(5)<-8\\4-15<-8\\-11<-8 \ (true)[/tex]

So, this ordered pair is solution of inequality as it satisfies the inequality.

So, Option B,C and E are solution to given inequality [tex]y - 3x < -8[/tex]

If x = 2

then

3(2)² - 2(2) + 1 = 3(4) - 4 + 1 = 12 - 4 + 1 = 13 - 4 = 9 #

Therefore, if x = 2 then it's 9

Answer:

[tex]n=5-2p[/tex]

Step-by-step explanation:

STEP 1: Rewrite the equation as  3 n + 6 p = 15 .

[tex]3n+6p=15[/tex]

STEP 2: Subtract  6 p  from both sides of the equation.

[tex]3n=15-6p[/tex]

STEP 3: Divide each term by  3  and simplify.

[tex]n=5-2p[/tex]

Complete question is;

A truck driver travels from a distributor to a retailer every week. The driver records the distance that he is from the retailer at different times during his trip. After several weeks of collecting data, the driver creates a scatter plot of the data. The best–fit line is y = 73.6 – 67.8x, where x is the number of hours spent driving and y is the distance, in miles, from the retailer.

Which of the following statements are true? Select all that apply.

The distance from the retailer increases with time.

The distance from the retailer decreases with time.

The distributor is 67.8 miles away from the retailer.

The distributor is 73.6 miles away from the retailer.

The truck is traveling at a rate of 67.8 miles per hour.

Answer:

B: The distance from the retailer decreases with time.

Step-by-step explanation:

Formula for best fit line is;

y = mx + b

Where;

m is slope

b is y-intercept

We are told that the best–fit line is y = 73.6 – 67.8x

This can be written as;

y = -67.8x + 73.6

This means the slope is negative and when x = 0, y = 73.6 which is the y-intercept.

We are told that x is the number of hours spent driving and y is the distance, in miles, from the retailer.

Since we have a negative slope, it means that y is decreasing with increasing values of x.

Thus, we can say that the distance from the retailer decreases with time.

Answer:

(x + 8)² = 36

Step-by-step explanation:

When you are trying to complete the square and the equation already has a constant, you add or subtract that value to the other side of the equation so you can cancel it out.

x² + 16x + 28 = 0

x² + 16x + 28 - 28 = 0 -28

x² + 16x = -28

Now, you find ([tex]\frac{b}{2}[/tex])² (divide b by 2 and raise the quotient to the second power). Half of 16 is 8, and 8² is 64. Add 64 to both sides.

x² + 16x + 64 = -28 + 64

x² + 16x + 64 = 36

Now, you just factor the equation on the left. To factor it, you will always use the number you got to make the constant, which in this case is 8.

(x + 8)² = 36

Answer: X = 5

Step-by-step explanation: Since a square has all equal sides, and area is just length times width, the other side has to be five. If you REALLY feel the need to check my work just do 5x5.

Answer:

v=99

Step-by-step explanation:

This is somewhat like a ratio problem. So, when v is 36, g is 4. We can simplify this. So, if we divided g by 4 we get one, and if we divide v by 4 we get 9. So, we have 1:9 ratio of g to v. If g is 11, then we multiply the 1 by 11 and the 9 by 11 also. Therefore, v is 99

Answer:

25 1/2 square meters remaining

Step-by-step explanation:

Total area of the pool deck=76 1/2 square meters

He painted 2/3 of the deck before stopping for lunch

Total painted=2/3 of 76 1/2

=2/3*153/2

=306/6

=51 square meters

Total remaining=Total area - total painted area

=76 1/2 - 51

=153/2 - 51

=153-102/2

=51/2

=25 1/2 square meters remaining

Answer:

X=8

Step-by-step explanation:

17x-4=12+15x

add 4 on both sides to get

17x=16+15x

now subtract 15x on both sides to get

2x=16

divide by 2 on both sides

you get

x=8

Answer:

14x>200+5.5, She must sell 15 or more vases

Step-by-step explanation:

14x>200+5.5

14x>200+5.5

14x>205.5

x>14.68*

She must sell 15 or more vases

*You round up because you cannot sell a partial vase

Answer:

14v > 200 + 5.50v, she will have to sell 24 vases to make a profit

Step-by-step explanation:

It costs $5.50 PER VASE for materials, so you would subtract this from what she sells each vase for. 14 - 5.50 = 8.50. She makes an $8.50 profit per vase sold. We can write 8.50n > 200 to show her profit margin minus the booth fee. If she sold 24 vases, she would be making a profit and this would represent the lowest amount of vases she can sell to make a profit. We can write the inequality 24 ≤ n to show that she can sell 24 vases or more to make a profit.

14n > 200 + 5.50n

336 > 332, true

n > 23

How to solve your question

Your question is 1/2(4x-2)=6x-3

Solve

1.Combine multiplied terms into a single fraction

1/2(4x-2)=6x-13

1(4x-2) divided by 2 =6x-13

2.Multiply by 1

3 Subtract 6x from both sides of the equation

4.Simplify

5.Multiply all terms by the same value to eliminate fraction denominators

6.simplify

7.Add 2 to both side of equation

8.Simplify

9.Divide both sides of the equation by the same term

10.Simplify

Step-by-step explanation:

Combine multiplied terms into a single fraction

1/2 (4x-2) / 2 = 6x - 13

1 (4x -2) /2 = 6x -13

Multiply by 1

1 (4x - 2) / 2 = 6x - 2

4x - 2 / 2 = 6x-13

Subtract 6x from both sides of the equation

4x - 2 / 2 = 6x - 3

4x - 2 /2 - 6x =6x -13 -6x

Simplify

Combine like terms

4x -2 /2 -6x = -13

Multiply all terms by the same value to eliminate fraction denominators

4x -2 /2 -6x = -13

2 (4x-2 /2 -6x) =2(-13)

Simplify

Distribute

Cancel multiplied terms that are in the denominator

Combine like terms

Multiply the numbers

-8x -2 = -26

Add 2 to both sides of the equation

-8x -2= -26

-8x -2+2 = -26+2

Simplify

Add the numbers

Add the numbers

-8x = -24

Divide both sides of the equation by the same term

-8x = -24

-8x / -8 = -24 / -8

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

=3

Answer:

Solving the equation [tex]\frac{a^2-b^2}{2+d^3}[/tex] by putting a=6, b=4 and d=1/2 we get [tex]\frac{160}{17}[/tex]

Step-by-step explanation:

We are given formula: [tex]\frac{a^2-b^2}{2+d^3}[/tex]

and values a=6, b=4 and d=1/2

We need to put the values of a, b and d in the given equation [tex]\frac{a^2-b^2}{2+d^3}[/tex] and find their result

Putting values in the equation:

[tex]\frac{a^2-b^2}{2+d^3}\\=\frac{(6)^2-(4)^2}{2+(\frac{1}{2})^3}\\=\frac{36-16}{2+\frac{1}{8}}\\=\frac{20}{\frac{2*8+1}{8}}\\=\frac{20}{\frac{17}{8}}\\=\frac{20*8}{17}\\=\frac{160}{17}[/tex]

So, solving the equation [tex]\frac{a^2-b^2}{2+d^3}[/tex] by putting a=6, b=4 and d=1/2 we get [tex]\frac{160}{17}[/tex]

Answer:

The answer is below

Step-by-step explanation:

So first to find a prime number, you need to know some multiplication skills.

So prime number is a number that is only divisible by itself or 1.

______

For example

3 is a prime number because it can't be divisible by any number

but

9 is not a prime number, because it can be divisible by 3

3 x 3 = 9

______________________

So you get it now

Now if you get a some number between 1 - 10

you have to use your multiplication skills to see if there are any prime numbers.

_____________________________

so

1  - not a prime number, can't be divisible by any number.

2 - not a prime number, can't be divisible by any number.

3 - not a prime number, can't be divisible by any number

4 - is a prime number, can be divisible a number (2 x 2 = 4)

5 - not a prime number, can't be divisible by any number

6 - is a prime number, can be divisible a number (3 x 2 = 6)

7 - not a prime number, can't be divisible by any number

8 - is a prime number, can be divisible a number (4 x 2 = 8)

9 - is a prime number, can be divisible a number (3 x 3 = 9)

10 - is a prime number, can be divisible a number (5 x 2 = 10)
