Let cosα = sinβ = 0.8957 and let 0° ≤ β ≤ 90°. if α = 26.4°, what is the value, in degrees, of angle β?

Find the solution of this system of equation -7x+y=-20 9x-3y=36

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 – 10x +2?

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part 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)
