Answer:
19 seconds.
Step-by-step explanation:
Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:
1 PM = 13:00
13 - 7 = 6
228/6 = 38
38/2 = 19
Thus, every half hour the clock is delayed 19 seconds.
The variable <em>x </em>is equal to 0.5
It would be A. 23/30 if it was not simplified but if you need it to be simplified it would be C. 1 3/20
Your welcome
B= -42 C= -38
So the difference going up to positive is 4 and the difference going down in negative is -4.
Answer: (-0.4, 6.8)
The graph is attached
Step-by-step explanation:
We can find the axis of symmetry using the formula x = -b/2a
x = - -4/2(-5)
x = 4/-10
x = 0.04
Substitute for x and calculate y
y = 
y = 6.8
