6 0

Answer:

(-1, -1) is not a solution to the system

Step-by-step explanation:

Y = 3x - 4.             Substitute the points for x and y

2 = 3(2) - 4

2 = 2  solution

y = 3x - 4

-4 = 3(0) - 4

-4 = -4 solution

y = 3x - 4

8 = 3(4) - 4

8 = 8   solution

y = 3x - 4

-1 = 3(-1) - 4

-1 = -7 not solution

Use mathematical induction to prove that the statement is true for every positive integer n. Show your work. 2 is a factor of n2
Lady_Fox [76]
Let n = 1
then f(1) = 1^1 - 1 + 2 = 2   so it is true for n = 1
for the next number  after n   ( n+1) we have  f(n+1) =
 (n+1)^2  - (n+1) + 2 

= n^2 + 2n + 1 - n - 1 + 2 

= n^2 + n + 2 

= n(n+1) + 2

Now n(n+1) must be divisible by 2  because  either n is odd and n+1 is even OR n is even and n+1 is odd   and odd & even always = an even number.

So the function is divisible by 2  for n+1   We have shown that its true for n = 1 Therefore it must be true for n = 1,2,3,4 ... 
True for all  positive integers

If zeina has seven times as many books as ali if zeina gave ali 15 books they would eash have the same number of books how many
kramer

Answer:

<em>Zeina had 35 books and Ali had 5 books</em>

Step-by-step explanation:

<u>Equations</u>

We know Zeina has seven times as many books as Ali. If we call

x = Number of books Ali has

Then Zeina has

7x = Number of books Zeina has

We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:

x + 15 = 7x - 15

Adding 15:

x + 15 +15 = 7x

Subtracting x:

15 +15 = 7x - x

Operating:

30 = 6x

Dividing by 6:

x = 30 / 6

x =5

7x = 35

Thus Zeina had 35 books and Ali had 5 books
