Which figure does NOT belong?
kvasek [131]

<u>Answer:</u>

C (third figure from left)

<u>Step-by-step explanation:</u>

The spirals in the first, second, and fourth figures are all clockwise from the outer end, i.e., if you trace these three spirals with your finger from the outside to the inside, your finger will move clockwise.

However, if you did the same with the third figure, you would see that the spiral is anti-clockwise from the outside moving in.

Therefore, the third figure doesn't belong.

Three consecutive integers are n, n, +1 and n+2. 4 times the sum of the least and greatest integers is 12 less than three times
raketka [301]

Answer:

The smallest integer is -4.

Step-by-step explanation:

4(n + n+2) = 3*n - 12                          Combine the left

4(2n + 2) = 3n- 12                              Remove the brackets

8n + 8 = 3n - 12                                 Subtract 3n from both sides

8n-3n + 8 = 3n-3n - 12                      Combine

5n + 8 = - 12                                      Subtract 8 from both sides

5n = - 12 - 8

5n = - 20                                           Divide by 5

5n/5 = -20/5    

n = - 4

n + 1 = -3

n + 2 = - 2

Solve the following system of equations and show all your work y=2x^2 y=3x-1
Ann [662]

Answer:

( 1/2 ; 1/2 ) and ( 1 ; 2 )

Step-by-step explanation:

y = 2x².............1

y = 3x-1............2

2x²=3x-1

2x²-3x+1 = 0

(2x-1)(x-1) = 0

x = 1/2 or x = 1

y = 1/2 or y = 2
