If cos(x)cos(π/7)+sin(x)sin(π/7)= - (√2)/2, then x can equal:
(check all that apply)
a. (π/4)+(π/7)+2nπ

b. (5π/4)+(π/7)+2nπ

c. (7π/4)+(π/7)+2nπ

d. (3π/4)+(π/7)+2nπ

Tell me how you got the it use the figures to answer questions 1and 2. in each diagram, line k is parallel to line l, and line t intersects lines. 1. based on the diagrams, what is the value of x? 2. how would you verify your answer for x?

I'll give brainliest if you answer right : )

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
