What is the slope and equation of a horizontal line ?

Answer:

16

Step-by-step explanation:

Given

u = x₁i + y₁j and v = x₂i + y₂j , then

u • v = x₁x₂ + y₁y₂

Given

u = - 4i + 8j and v = - 2i + j , then

u • v = ( - 4 × - 2) + (8 × 1) = 8 + 8 = 16

Answer:cost of each pound of apple= $3

And cost of each pound of orange =$2

Step-by-step explanation:

Step 1

Let cost of apples = x

And cost of Oranges =y

Let 6 pounds of apples and 3 pounds of oranges cost 24 dollars be represented as

6 x + 3y= 24----- equation 1

Also, Let 5 pounds of apples and 4 pounds of oranges cost 23 dollars be represented as

5x+ 4y= 23----- equation 2

Step 2

6 x + 3y= 24----- equation 1

5x+ 4y= 23----- equation 2

Using substitution method to solve the equation

6 x + 3y= 24

24-6x=3y

y= 24-6x/3 = 8-2x

Y= 8-2x

Substituting the value of y= 8-2x  into equation 2

5x+ 4( 8-2x)= 23

5x+ 32 -8x= 23

32-23= 8x-5x

9=3x

x=9/3

x=3

Putting the value of x= 3 in equation 1 and solving to find y

6 x + 3y= 24

6(3) +3y= 24

18+3y=24

3y= 24-18

3y=6

y=6/3= 2

Therefore the cost of each pound of apple= $3

And cost of each pound of orange =$2

Answer:

I actually can't measure it, but if you will and cmt the measures, I can help you round them!!!

Step-by-step explanation:

Hey there!

- Factor pair basically 2 factors that you multiply the given numbers to each other to get a given product (answer)

“Factors of 72”

- So we have to find MULTIPLES that gives you 72

Answers ⬇️

▸ 1 • 72 = 72

(SAME thing with 72 • 1 = 72)

▸ 2 • 36 = 72

(SAME with 36 • 2 = 72)

▸ 3 • 24 = 72

(SAME with 24 • 3 = 72)

▸ 4 • 18 = 72

(SAME with 18 • 4 = 72

▸ 6 • 12 = 72

(SAME with 12 • 6 = 72)

▸ 8 • 9 = 72

(SAME with 9 • 8 = 72)

Good luck on your assignment and enjoy your day!

Answer:

Step-by-step explanation:

42:7=ED:24

cross multiply 42 into 24.

Then divide by 7

you will get ED

Then use pythageorous theorem.

Then do square root of Ef square

Answer:

-3x - 18

Step-by-step explanation:

Use the distributive property.

-3(x + 6) = (-3)(x) + (-3)(6) = -3x - 18

Answer:

-3x-18

Step-by-step explanation:

Use the distributive property to simplify

-3(x+6)

(-3*x)+(-3*6)

-3x+(-18)

-3x-18

Answer:

Answer:

23.75

Step-by-step explanation:

Given that:

Brian's age = 27

Age of Chris is 17 more than one - fourth of Brian's age.

To find:

Age of Chris = ?

Solution:

Let age of Chris = [tex]x[/tex]

One - fourth of Brian's age =  [tex]\frac{27}{4}[/tex]

17 more than One - fourth of Brian's age = [tex]\frac{27}{4}[/tex] + 17

Therefore, we can write the equation as per question statement:

[tex]x = \frac{27}{4} + 17\\\Rightarrow x = 6.75+17\\\Rightarrow \bold{x = 23.75}[/tex]

Therefore, Chris is 23.75 years old if Brian is 27.

Answer: 39.9

Step-by-step explanation: 9.5×4.2

Answer:

7+2(a-3)=-9

a= -5

Step-by-step explanation:

7+2(a-3)=-9

Distribute 2 through the parentheses

Example: 7+2a-6=-9

Next: 7+2a-6=-9

Subtract the numbers

1+2a=-9

Move constant to the right hand side and change its sighn 2a=-9-1

2a=-9-1

Calculate the difference

2a=-10

Divide both sides of the equation by 2

Answer: a=- -5

Answer:

29/22

Step-by-step explanation:

Let x = 1.31818181818....

Then, 10x = 13.18181818..., and 1000x = 1318.18181818..... Subtracting the first equation from the second, we get that 990x = 1305. This means that x = 1305/990. In lowest terms, this is 29/22.

Step-by-step explanation:

Answer:

y -3 = (-1/2)(x - 5)

Step-by-step explanation:

Slope of line:  Notice that if we go from 7 to 5, the 'run' is -2 and the corresponding 'rise' from 2 to 3 is 1.  Thus, the slope is m = -1/2.

Using m = -1/2 and the point (5, 3), we write the equation of this line in point-slope form as:

y -3 = (-1/2)(x - 5)

Answer:

2 1/5 meters

Step-by-step explanation:

Given that:

Area of kitchen = 3 3/4

Width of kitchen = 1 1/2

Length = x

Recall : Area of rectangle = Length * width

Area of kitchen = length * width

3 3/4 = x * 1 1/2

15 / 4 = x * 3/2

x = 15/4 ÷ 3/2

x = 15/4 * 2/3

x = 30/12 = 2 6/30

x = 2 1/5
