Elimination was used to solve a system of equations. One of the intermediate steps led to the equation 3x = 18.
Which of the following systems could have led to this equation?
2x + y = 24
- x - y = 6
x + y = 4
x - 2y = 10
3x + y = 18
- 3x - y = - 18
4x + y = 20
x - y = 2

Given the function f(x) = log base 4(x+8) , find the value of f^-1(2)

Do more republicans (group a) than democrats (group b) favor a bill to make it easier for someone to own a firearm? two hundred republicans and two hundred democrats were asked if they favored a bill that made it easier for someone to own a firearm. how would we write the alternative hypothesis?

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)
