Answer:

-9

Step-by-step explanation:

Answer:

slope = - 9

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (5, - 6) and (x₂, y₂ ) = (4, 3)

m = [tex]\frac{3+6}{4-5}[/tex] = [tex]\frac{9}{-1}[/tex] = - 9

Answer:

5

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/ (x2-x1)

   = (-3-3)/(4-1)

  =-6/3

  = -2

Then we can use point slope form to make the equation

y-y1 = m(x-x1)

y-3 = -2(x-1)

Distribute

y-3 = -2x+2

Add 3 to each side

y-3+3 = -2x+2+3

y = -2x+5

Since this is in slope intercept form, y = mx +b, the y intercept is 5

Answer: D. 5

Step-by-step explanation: First we need to find the slope

m = (y2-y1)/ (x2-x1)

  = (-3-3)/(4-1)

 =-6/3

 = -2

Then we can use point slope form to make the equation

y-y1 = m(x-x1)

y-3 = -2(x-1)

Distribute

y-3 = -2x+2

Add 3 to each side

y-3+3 = -2x+2+3

y = -2x+5

Since this is in slope intercept form, y = mx +b, the y intercept is 5

Answer:  Graph (-4, -2) and (-2, 1)

Step-by-step explanation:

[tex]\text{The given equation is: }y+2=\dfrac{3}{2}(x+4)\\\\\text{which is of the form: }y-y_1=m(x-x_1)\\\implies(x_1, y_1)=(-4, -2)\quad and \quad m=\dfrac{3}{2}\implies (x+2, y+3)\\\\.\qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad (-4+2, -2+3)=(-2, 1)[/tex]

Answer:

C. a rotation about point L

Step-by-step explanation:

Answer:

(0, 1)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y - 4x = 1 ( add 4x to both sides )

y = 4x + 1 ← in slope- intercept form

with y- intercept c = 1 ⇒ (0, 1) ← coordinates of y- intercept

The coordinates of the point where y-4x=1 crosses the y axis is (0, 1)

The following information should be considered:

Therefore we can conclude that The coordinates of the point where y-4x=1 crosses the y axis is (0, 1)

Answer:

4 1/8 pieces

Step-by-step explanation:

Since you are using a string that is 100 ft. long then and you need exactly 24 3/8 ft. sections, you would do these calculations:

3/8 = 0.375

100/24.375 = 4.1026

.1026 = 1/8

4 1/8 ft long pieces

Answer:

The string is cut into 4.1025 pieces.

Step-by-step explanation:

We are given the following information:

Length of the string =  100 feet

Length of one piece = [tex]24\displaystyle\frac{3}{8} = \displaystyle\frac{195}{8} ~feet[/tex]

Number of pieces =

Formula:

[tex]\text{Number of pieces} = \displaystyle\frac{\text{Length of string}}{\text{Length of one piece}}[/tex]

Number of pieces =

[tex]\displaystyle\frac{100}{\frac{195}{8} } = \displaystyle\frac{100\times 8}{195}\\\\=\displaystyle\frac{800}{195} = 4\displaystyle\frac{4}{39} = 4.1025[/tex]

Thus, the string is cut into 4.1025 pieces.

Answer:

1 mi/1.61 km

Step-by-step explanation:

we know that

1 mile= 1.61  kilometers

To convert 1 kilometer to miles

use proportion

so

1/1.61 mi/km=x/1 mi/km

x=1 mi/1.61 km

Answer:

[tex]\frac{1 mi}{1.61km}[/tex]

Step-by-step explanation:

We are given the unit values of inch, foot and mile to convert into centimeters.

Using these conversion units, we are to determine whether which expression in the answer options can be used as the conversion factor to convert kilometers to miles.

So using the given conversion units, we can see that the following is the conversion factor to convert kilometers to miles.

Answer:

X= All real Numbers

Step-by-step explanation:

Answer:

All real numbers

Step-by-step explanation:

The domain is the set of x values that we can plug into the function and it will have a y value.

The domain is the "allowed" x values of a function.

Exponential functions of the form  [tex]y=a^x[/tex], where a is a constant have domain of "all real numbers".

The function in this problem is of this form with a "-5" at the end, which shifts the function vertically 5 units down. This doesn't affect x values (or domain)

Hence, the domain is the set of all real numbers.

Answer:

36

Step-by-step explanation:

The 10 part of the ratio represents 120 chickens. Divide 120 by 10 to find the value of one part of the ratio.

120 ÷ 10 = 12 ← value of 1 part of the ratio, hence

3 parts = 3 × 12 = 36 ← number of horses

The number of horses on the farm is​ 36.

Given that, the ratio of chicken to pigs to horses on a farm is 10:2:3 and the number of chickens on the farm is 120.

Ratio, in math, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.

We can write the given ratio 10:2:3 as 10x: 2x: 3x.

So, 10x=120

⇒x=12

Then, the number of horses=3x=36

Therefore, the number of horses on the farm is​ 36.

Answer:

Say that the price at the whole for a bottle is some x

We know that the Snack Bar sold them at 33% profit which is in dollars $0.28

i.e 33% x=0.28

so now its a matter of finding what x is 

writing this in algebraic form

0.33x=0.28

divide both sides of the equation by 0.33

0.33x/0.33=0.28/0.33

Therefore x=0.85 roughly

so the price per bottle at the whole sell is 85 cent

the snack bar is selling it for 1.13 dollars

Step-by-step explanation:

you have a 1/12.5 chance of getting a white egg. so the theoretical possibility of getting only two white eggs is 1/156.25. so it is very unlikely to get two white eggs

Answer:

0.029

Step-by-step explanation:

Last year, the porgs laid 30 dotted eggs, 40 grey eggs, and 15 white eggs.

Total eggs = 30+40+15 = 85 eggs

White eggs = 15

So, probability of getting 1 white egg = [tex]\frac{\text{No. of white eggs}}{\text{Total no. of eggs}}[/tex]

                                                              = [tex]\frac{15}{85}[/tex]

Remaining white eggs = 14

Total eggs remaining = 84

Probability of getting 1 white egg on second draw   = [tex]\frac{14}{84}[/tex]

So, the probability that you would only collect 2 white eggs =[tex]\frac{15}{85} \times \frac{14}{84}[/tex]

                                                                                                   =0.029

Hence the probability that you would only collect 2 white eggs is 0.029.

Answer:

-7.2

Step-by-step explanation:

The value of expression A•D²/C² is 1.8 x 10⁻⁷ / D².

To find the value of A•D²/C², we can first rearrange the given equations and then manipulate them to get the desired expression.

Given equations:

A • B² = 1.8 x 10⁻⁷

C • B/D = 7.2 x 10⁻⁴

Let's manipulate the second equation to get C by itself:

C • B/D = 7.2 x 10⁻⁴

C = (7.2 x 10⁻⁴) • (D/B)

Now, substitute the expression for C from the second equation into the first equation:

A • B² = 1.8 x 10⁻⁷

A = (1.8 x 10⁻⁷) / B²

Now, we have expressions for both A and C:

A = (1.8 x 10⁻⁷) / B²

C = (7.2 x 10⁻⁴) • (D/B)

Now, let's find the value of A•D²/C²:

A•D²/C² = ((1.8 x 10⁻⁷) / B²) • (B/D)²

Since (B/D)² = B²/D²:

A•D²/C² = ((1.8 x 10⁻⁷) / B²) • (B²/D²)

Now, B² in the numerator and denominator cancel out:

A•D²/C² = 1.8 x 10⁻⁷ / D²

Thus, the value of A•D²/C² is 1.8 x 10⁻⁷ / D².
