Answer:

x = 0

Step-by-step explanation:

-3x - 3(6x - 1) = 3(1 - 5x)

Distribute

-3x -18x +3 = 3 -15x

Combine like terms

-21x +3 = 3 -15x

Add 21x to each side

-21x +21x+3 = 3 -15x+21x

3 = 3+6x

Subtract 3 from each side

3-3 = 3-3+6x

0 = 6x

Divide by 6

0/6 = 6x/6

0= x

Answer:

1996

Step-by-step explanation:

To find the number of terms in an arithmetic sequence, divide the common difference into the difference between the last and first terms, and then add 1.

2008 - 13 = 1995 + 1 = 1996

Point M is the midpoint of AB. The coordinates of point A are (-8, 3) and the coordinates of M are (-2, 1). What are the coordin
ch4aika [34]

Answer:

the coordinates of point B are (-5, 2)

Step-by-step explanation:

1. use midpoint formula to find the midpoint (equation attached below)

2. plug in the numbers

(\frac{-8+(-2)}{2},\frac{3+1}{2})

3. solve

(\frac{-8-2)}{2},\frac{3+1}{2})

(\frac{-10}{2},\frac{4}{2})

(-5,2})

There are 276 students.
Lynna [10]

Step-by-step explanation:

Number of males is

  • 276 - 158 = 118

Number of males not enrolled

  • 118 - 82 = 36

Number of females not enrolled

  • 158 - 102 = 56

(a)

The table based on data is

<u>                 Enrolled        Not enrolled      Total  </u>

<u>Male            82                  36                     118    </u>

<u>Female        102                56                     158   </u>

Total            184                 92                     276

(b)

Percentage of students were males that went to magic college

  • enrolled male / total students =           (use table above)
  • 82/276*100% = 29.71% (rounded)

(c)

Percentage of females went to magic college

  • enrolled female / total female =           (use table above)
  • 102/158*100% = 64.56% (rounded)

Let y(????)y(t) be a solution of y˙=17y(1−y7)y˙=17y(1−y7) such that y(0)=14y(0)=14. Determine lim????→[infinity]y(????)limt→[inf
shtirl [24]

Answer:

Step-by-step explanation:

Given that,

y' = 17y ( 1-y^7)

Let y=1

Then, y' = 0 for all t

Then show that it is the only stable equilibrium point so that as y→1, t→∞ with any initial value.

So, the graph solution will be

y(0) = 1 and this will be an horizontal line

If, y(0) > 1 then, y' < 0 by inspecting the first equation, so the graph is has decreasing solution.

Likewise, if y(0) < 1 then, y' > 0 and the graph is increasing.

So no matter the initial condition, graph of the solution will be asymptotic to the horizontal line above.

This make the limit be 1.

This shows that x = 1 is a stable equilibrium.
