Answer:
B
Step-by-step explanation:
f(x) = x²+49 , rewrite the equation
x² +7² =0 , to find the roots make f(x) =0 and subtract 7² from both sides
x² = -7², square root both sides
√x² =√-7², consider √-1 =i
x= ±7i
the roots are -7i and 7i

This system of inequalities models the scenario:
2x + y = <8
x + y > 4
Part A: Describe the graph of the system of inequalities, including shading and the types of lines graphed. Provide a description of the solution set. (4 points)
Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically. (3 points)
Part
Answer:
91
Step-by-step explanation:-5, 1, 7, 13
the common diference is : d = ( 13)-(7)=(7)-(1)=(1)-(-5)=6
the firt term is A1 = -5
the n-ieme term is : An = A1 +(n-1)d
An = -5+6(n-1)
An = 6n-11
the 17th term in the arithmetic sequence is : A17 = 6(17)-11 =91
