**analytic geometry**

a line connecting coordinates (x,7) and (10, y) is selected at (8,0) find x find y find equation of line

**math**

Find the slope of the line whose parametric equations are x=2-t and y=1=2t fi this line passes through (2,y) find the value of y compute also the value of t

**chemistry**

Determine how many milliliters of 0.255 M HClO4 will be required to neutralize 48.56 g Ca(OH)2 according to the reaction: 2HClO4(aq)+Ca(OH)2(s)=CA(ClO4)2(aq)+2H2O(l)
