Step-by-step explanation:

Given 

f(x) = x² - 2x + 3

Now

f(-2) = (-2)² - 2 * ( -2 ) + 3

 = 4 + 4 + 3

 = 11

f(3) = 3² - 2 * 3 + 3

 = 9 - 6 + 3

 = 12 - 6

 = 6

Hope it helps :)

Answer:

165 ways to choose the paintings

Step-by-step explanation:

This is clearly a Combination problem since we are selecting a few items from a group of items and the order in which we chosen the items does not matter.

The number of possible ways to choose the paintings is;

11C3 = C(11,3) = 165

C denotes the combination function. The above can be read as 11 choose 3 . The above can simply be evaluated using any modern calculator.

Can someone explain this for me?? 4 (c+2) < 4c + 10

faust18 [17]

Answer:

The inequality would be true

Step-by-step explanation:

4(c+2) < 4c + 10

Distribute the 4 on the left

4c + 8 < 4c + 10

Subtract 4c from both sides

8 < 10

8 < 10 is true

10=c+d c is one more than d what is the value of c? with working out

Leya [2.2K]

C= 5.5 I'm pretty sure that's the answer

d= 4.5 and c+ 5.5
Because 4.5 plus 1.0 = 5.5
since c is one more than d

5.5 plus 4.5 = 10
