  • Think of it this way. A solution is defined as a mix of 2 or more substances. In this mix, a solute is dissolved in a solvent. Soda is definitely a mix, just look at all of the ingredients, and being a liquid it is a solution. Bronze is generally made from a make of tin and copper, so being a mix, it is out. Mud in water is a solution, just try and name everything in dirt. However, air in a scuba tank does not mix. It is air, so that is your answer.

  • to clean up this, you graph the appropriate equation which means you modify the extra advantageous-than-or-equivalent-to sign to an equals. x+2y=3 and 2x-3y=6. the subsequent step is to place it in y=mx+b variety x+2y=3 -3 -3 x+2y-3=0 -2y -2y -2y=x-3 divide the two factors by using -2 y= -0.5x+a million.5 this line will intersect the y-axis on the factor a million.5, so start up there.(b=y-intersept) the slope is -0.5 (m is the slope) that’s one a million/2. Slopes are written upward thrust over run, so for one and all area it video clips down, this is going to circulate over 2 to the suitable. then, you will desire to discover which facet to shade in which would be x and y %. a factor on the left and suitable facet of the line that became drawn and if it particularly works, interior the unique equation, then shade that facet in. all of the standards on that facet will paintings. try this with the different equation besides
