Ntrapezoid, two triangles are formed by the bases and the intersecting diagonal segments. the areas of these triangles are s1 and s2. find area of the trapezoid in terms of s1 and s2.

What is the x-intercept and y-intercept of the equation 2x+1. 2o

What is the solution to the system of equations? y=1.5-3 y=-x

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
