Answer:
y = 2x^2 − 4x + 5
y = 2(x^2 − 2x) + 5
y = 2(x^2 − 2x + 1 - 1) + 5
y = 2(x^2 − 2x + 1) + 5 - 2
y = 2(x - 1)^2 + 3
x = 1 is the axis of symmetry.
Do you agree?
Do a proportion and then youll get the things you need to make the equation using x =
1. he ate 1/4 of the bucket
2. 4 of the pool floaties are yellow.
3. she paid 4$ for the cookies
4 . 3 members of the band play the drums
5. 45 minutes
14. Was the perimeter calculated correctly?
- Breadth = 1 *2/5 yards = 7/5 yards
We know that,
Perimeter of rectangle = 2 ( l + b )
= 2 ( 4 + 7 / 5 )
= 2 ( 20 + 7 / 5 )
= 2 × 27/5
= 54 / 5
= 1 * 4/5
No ...
Divide both the numerator and the denominator by 4, so 12/20 becomes 3/5.
