You use substitution or elimination.
Answer:
Yes it is in fact a function.
Step-by-step explanation:
Since there is one value of y for every value of x in the question
Answer:
Step-by-step explanation:
4 1/2 minutes = 4.5 minutes
2 / 4.5 = 0.44 laps per minute
OR
4.5 / 2 = 2.25 minutes per lap
not sure which one ur looking for...but both are unit rates
Answer:
I believe the answer would be answer choice 'A'.
f(x)= -2x-3
Step-by-step explanation:
Step 1:
Let the sequence given here is -5, -7, -9, -11, -13 ......
Here the first term (a₁) of sequence is -5
And the common difference between the numbers in the sequence is
d= (-7-(-5)) = -7+5 = -2
Let the number of terms be x
Step 2;
To find the sequence function basic arithmetic sequence formula is
aₙ = a₁ + d( x-1)
Applying the values we get
f(X) = -5 + ((-2)(X-1))
on simplification
f(X) = -5 + (-2X+2)
f(X)= -5+2-2X
f(X)= -3-2X
