The equation shows the relationship between x and y:
2 answers:
Answer:
The correct option is 2. The slope of the equation is -9.
Step-by-step explanation:
The given equation is
..... (1)
The slope intercept form of a line is
.... (2)
Where, m is the slope and b is y-intercept.
On comparing (1) and (2), we get
and
Therefore, the slope of the equation is -9 and y-intercept is (0,5). Option 2 is correct.

Answer:
Problem 1) frequency: 160 heartbeats per minute, period= 0.00625 minutes (or 0.375 seconds)
Problem 2) Runner B has the smallest period
Problem 3) The sound propagates faster via a solid than via air, then the sound of the train will arrive faster via the rails.
Step-by-step explanation:
The frequency of the football player is 160 heartbeats per minute.
The period is (using the equation you showed above):
second problem:
Runner A does 200 loops in 60 minutes so his frequency is:
loops per minute
then the period is: 0.3 minutes (does one loop in 0.3 minutes)
the other runner does 200 loops in 65 minutes, so his frequency is:
loops per minute
then the period is:
Therefore runner B has the smaller period
Hi there! The answer is FALSE
To find the answer we need to work out the parenthesis.
75 does not equal 45 and therefore the statement is false.
