Write a vector equation of the line that passes through P(-1, 6) and is parallel to ä = (3. - 1)

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

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?
