Answer:

y = -3x

Step-by-step explanation:

Substitute the numbers into the point-slope form equation:

y - 0 = -3(x - 0)

y = -3x

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

Explanation:

The dot plot indicates we have this data set: {20, 23, 25, 28}

Add up those values to get 20+23+25+28 = 96

Then divide by 4 since there are 4 values being added up here

96/4 = 24

So the arithmetic mean is 24.

Answer:

The answer is "19.71 million".

Step-by-step explanation:

[tex]\to P(t) = \frac{19.71}{1+61.22 e^{(-0.03513t)}}[/tex]

where

[tex]\to p= \text{population in million} \\\\\to t= \text{time in years}\\[/tex]

when t is increases, then [tex]61.22 \ e^{-0.035 t}=\frac{61.22}{e^{0.035t}}[/tex] when decrease so that p(t) continually grows in size to reach the optimum population which you find if t is quite high [tex]t \to \infty[/tex]

[tex]\to P_{max} = \lim_{ \ t \to \infty} \frac{19.71}{1+61.22 e^{(-0.03513t)}}[/tex]

[tex]when \ t \to \infty \ , 0.035 t \to \infty \ , e^{(0.03513t)} \to e^{\infty} \to \infty\ \ e^{\frac{1}{0.035t} = \ e^{-0.035t}} \to 0[/tex]

           [tex]= \frac{19.71}{1+0}\\\\= \frac{19.71}{1}\\\\ = 19.71 \ million[/tex]

Answer:

(2, - 1 )

Step-by-step explanation:

Given the 2 equations

y = 4x - 9 → (1)

y = x - 3 → (2)

Substitute y = 4x - 9 into (2)

4x - 9 = x - 3 ( subtract x from both sides )

3x - 9 = - 3 ( add 9 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into either of the 2 equations for y

Substituting into (2)

y = 2 - 3 = - 1

solution is (2, - 1 )

Answer:

Step-by-step explanation:

8x6+(8)/2

48+4

42

Answer:

52

Step-by-step explanation:

So in order to answer this question we are going to have to use the order of operations by starting with the parenthesis of subtracting 4 from 12:

8 × 6 + (12 - 4) ÷ 2​

12 - 4 = 8

Now the equation looks like this:

8 × 6 + 8 ÷ 2

Now we multiply 8 by 6 and dividing 8 by 2 because multiplication and division come first​:

8 * 6 = 48

8/2 = 4

So the equation looks like this:

48 + 4

We now add them together to get our answer:

48 + 4 = 52

So the answer to this equation is 8 × 6 + (12 - 4) ÷ 2​ = 52

Hope this helps you

40*.20=8

40-8=32

32*.05=1.60

32-1.60=30.4

Answer:

(-2,10)=x1,y1

(1,1)=x2,y2

we have,

(y-y1)=(y2-y1)/(x2,x1)[(x-x1)]

(y-10)=(1-10)/(1+2)[x+2]

y-10=-9/3(x+2)

y-10=-3(x+2)

y-10=3x+6

y=3x+16

Answer:

Step-by-step explanation:

The slope of a line passing through two points: (x₂, y₂) and (x₁, y₁) is:

                                                                               [tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

(-2, 10)  ⇒  x₁ = -2,  y₁ = 10

(1, 1)    ⇒  x₂ = 1,  y₂ = 1

So:

      [tex]\bold{m=\dfrac{1-10}{1+2}=\dfrac{-9}{3}=-3}[/tex]

The point-slope form of equation of line is y - y₀ = m(x - x₀)

We can pick any of given poins, so:

x₀ = 1,  y₀ = 1   and  m = -3

y - 1 = -3(x - 1)

y = -3x + 3 + 1

y = -3x + 4      ←  slope intercept form of the line

Answer: x < 100 , where x  = the temperature of a pot of water ( in degrees Celsius).

Step-by-step explanation:

The boiling point of water is 100 degrees Celsius.

The temperature of water that is not boiling must be less than 100 degrees Celsius.

Let x  be the temperature of a pot of water ( in degrees Celsius).

Then, as per given,

x < 100

hence, the  inequality to represent a pot of water that is not boiling.:

x < 100
