Answer:
2n - 11
Step-by-step explanation:
Note there is a common difference d between consecutive terms of the sequence, that is
d = - 7 - (- 9) = - 5 - (- 7) = - 7 + 9 = - 5 + 7 = 2
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 2, thus
= - 9 + 2(n - 1) = - 9 + 2n - 2 = 2n - 11
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Isolate the variable y
Divide by -2 both sides
The solution of the inequality is the shaded area below the dashed line
To plot the inequality find the intercepts
The y-intercept is the point (0,3) (value of y when the value of x is equal to zero)
The x-intercept is the point (-12,0) (value of x when the value of y is equal to zero)
Plot the intercepts
Drawn the dashed line
shaded the region below the dashed line
