Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point B to point D and intersect at point E. All sides are congruent. Angle B E A is (3 x minus 12) degrees. What value of x will make parallelogram ABCD a rhombus?

x =

15 there is a line that includes the point 0,10 and has a slope of 7/4. what is it’s equation in slope intercept form

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
