What digits can be in the ones place of a number that has 5 as a factor?

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

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)

Which of the following is best modeled using a linear equation y=ax+b, where a is less than 0?
