Q No.5:Solve by adding or subtracting.2x+2y=-42x+4y=-12Q No.6:Solve the linear system model by multiplying first .The drama club had a car wash as a fundraiser where they washed a total of 41 vehicles.Members washed x cars at $5 each and y trucks at $8 each and made a total of $250.The system of equations (1) x+y=41 (2)5x+8y=250 can be used to represent this situation.Find the number of each of vehicle they washed.Q No.8:Graph the system of linear inequalities.Give two ordered pairs that are solutions and two that are not solutions.y(> and the line under it)3x+3y<-2p.s. Please please please help me out if you know how to do this i beg you its for a test and i really need it done.itll mean a million. please

Answer:No. 5 - x =2. y = -4No. 6 - y = 15. x = 26No. 8 - Solutions (-3, -3) (-3, -4) Not Solutions (0,0) (1,0Step-by-step explanation:No. 5 - When solving a system of equations the goal is to eliminate one of the variables (x or y) so that you can solve for the other. - For this problem you can subtract one equation by another because both of the equations have 2x in them, so when you subtract them you eliminate x. - Now you solve for y which gives you y = -4- Now plug in -4 for y in either of the two equations to solve for x and you then have both solutionsNo. 6 - First you must multiply one of the equations to make it have the same number in front of either x or y ( I chose x)- Then repeat the same process as number 5, 1. subtract, 2. solve for y, 3. plug in y to one of the other equations tosolve for xNo. 8 - start by graphing the lines as if the greater than/less than symbols are equal signs - If the sign has the line under it ("or equal to") then draw the graph as a solid line. If it does not have the line under it drw the graph dashed. If it is solid, points on that line are solutions, if it is dashed points on the line are not solutions- Since it is a system the solutions must be points that follow the rules of both inequalities. The shaded area on the graph I drew is the area where points are solutions. - To figure out which side of the graph is the side with the solutions plug in a coordinate pair from that side, if the resulting statement is true, then that side has the solutions on itI hope this helps sorry it took so long there's a lot here I hope it's not too confusing
