For this case we have the following equation:
 y = x2-4x + 3
 Deriving we have the following equation:
 y '= 2x-4
 We equal zero and clear x:
 2x-4 = 0
 x = 4/2
 x = 2
 Substituting in the given equation we have:
 y = (2) ^ 2-4 (2) +3
 y = 4-8 + 3
 y = -1
 The vertex will be the ordered pair:
 (x, y) = (2, -1)
 Answer:
 
(x, y) = (2, -1)
 
option B

The answer is 2,-1 hopefully so x is 2 and you subtract it with 4x then its going to come 2 then you subtract 3 and 2 equal 2,-1 i am not really sure but yeah

If you put it in the calculator as 12÷15-3÷10, you get 0.5. you could simplify, but you might get a different answer.

Help Please I'm Out Of Time ;(
trasher [3.6K]

Answer:

Total area = 31.5 unit²

Step-by-step explanation:

Assume 1 block = 1 unit²

Divide diagram into 3 part

1. 5 by 5 block square

2. 2 by 2 block triangle(1)

2. 3 by 3 block triangle(2)

Area of square = side × side

Area of square = 5 × 5

Area of square = 25 unit²

Area of triangle(1) = [1/2][base][height]

Area of triangle(1) = [1/2][2][2]

Area of triangle(1) = 2 unit²

Area of triangle(2) = [1/2][base][height]

Area of triangle(2) = [1/2][3][3]

Area of triangle(2) = 4.5 unit²

Total area = Area of square + Area of triangle(1) +Area of triangle(2)

Total area = 25 unit² + 2 unit² + 4.5 unit²

Total area = 31.5 unit²

Can some one please help me to teach this to my daughter
EastWind [94]
28mi/1 hr = 28 mi/60 min = 1 mi/(60/28) min = 

28 mi/hr = 28 mi/60 min since there are 60 min in 1 hr
1 mi/(60/28) min since you divide top and bottom of 28/60 by 28 to get
1 mi/(60/28) min = 1mi/(15/7) min = 1 mi/ 2 1/7 min
