Answer:
c = 121
Step-by-step explanation:
Given
t² - 22t
To complete the square
add ( half the coefficient of the t- term )² to t² - 22t
= t² + 2(- 11)t + (- 11)²
= t² - 22t + 121
with c = 121
Thus
t² - 22t + 121 = (t - 11)²

Answer:
The step 3 is incorrect in the conversion, is not necessary
Step-by-step explanation:
we have
The speed is 
we know that
1 mm=0.1 cm
1 min=1/60 h
so

step 1
Multiply 76 by 0.1

The step 1 is correct
step 2
Multiply the result obtained in step 1 by 60.

The step 2 is correct
step 3
Multiply the result obtained in step 2 by 60
<u><em>This step is not correct</em></u>
therefore
The step 3 is incorrect in the conversion, is not necessary

Answer:
y = 4x + 4
Step-by-step explanation:
Plug in your x and y coordinates
8 = 4(1) + b
8 = 4 + b get your constants together by subtracting 4 from both sides
4 = b
Hope this helps
