Given: y = 2x^2 - 32x + 56
1) y = 2 [ x^2 - 16x] + 56
2) y = 2 [ (x - 8)^2 - 64 ] + 56
3) y = 2 (x - 8)^2 - 128 + 56
4) y = 2 (x - 8)^2 - 72 <----------- answer
Minimum = vertex = (h,k) = (8, - 72)
=> x-ccordinate of the minimum = 8 <-------- answer
Step-by-step explanation:


Adding and subtracting 64 :
![y=2(x^2-16x+64-64+28)[tex]y=2(x^2-16x+64) +2(-64+28)](https://tex.z-dn.net/?f=y%3D2%28x%5E2-16x%2B64-64%2B28%29%3C%2Fp%3E%3Cp%3E%5Btex%5Dy%3D2%28x%5E2-16x%2B64%29%20%2B2%28-64%2B28%29)

Using identity : 


Putting, x = 8

y = -72

Answer:
4y+11x+24=0
Step-by-step explanation:
Slope is (7-(-4))/(1-5)=-11/4.
The equation is y-a=m(x-b).
y-5=(-11/4)(x+4)
4y-20=-11x-44, 4y+11x+24=0
One minute is 60 seconds so 2 minutes are 120 seconds :)))
Answer:
77°
Step-by-step explanation:
Complementary angles formula
90°- x°. (X is the given angle)
So,
90°-13°
= 77°
16x = 45 - 29
16x = 16
x = 16/16
x = 1
