Answer:
y = 9
Step-by-step explanation: this is because when x is 5 and is multiplied by -6 u get -30. from there u substratc -30 from -57 and get -27. so y is 9
Answer:
2 or 12
Step-by-step explanation:
The answer that we will use this equation 1/t1 +1/t2=1/ttotal
where t1 is the time of smaller pipe while t2 is the of the larger pipe
Given t total =4 while t2 is equal to t2=t1-6
So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4
8( t1-3)=(t1^2-6t1)
t1^2-14t1+24=0
t1=2 or 12
You are a right triangle. You can tell this by both the 3 sides and the 90 degree angle.
Answer:
47 bpm
B
Step-by-step explanation:
Draw a trend line (attached).
Reading from the graph, the resting hear rate, in bpm, of a person who exercises an average of 8 hours a week is approximately 47.
The only scatter plot that suggests a linear relationship between x and y is graph B (see second attachment) as the trend line is a straight line.
For step 2 it should be x^2-16x+73
