Paul was asked to use the elmination to find the solution to the system of linear equations 5x + 4y = 1 −2x − 8y = −26 what are the missing steps in his work below? 5x + 4y = 1 −2x − 8y = −26 10x + 8y = 2 + (−2x −8y = −26) 8x + 0y = −24 8x = −24 x = −3 5x + 4y = 1 5(−3) + 4y = 1 −15 + 4y = 1 4y = 16 y = 4 select one: a. 5x + 4y = 1 + (−2x − 8y = −26) b. 2⋅[5x + 4y = 1] 10x + 8y = 2 c. 5x + 4y = 1 − (−2x − 8y = −26) d. −5⋅[−2x − 8y = −26] 10x + 40y = 130

Acompany manufactures x units of product a and y units of product b, on two machines, i and ii. it has been determined that the company will realize a profit of $3 on each unit of product a and $4 on each unit of product b. to manufacture a unit of product a requires 7 min on machine i and 5 min on machine ii. to manufacture a unit of product b requires 8 min on mchine i and 5 min on machine ii. there are 175 min available on machine i and 125 min available on machine ii in each work shift. how many units of a product should be produced in each shift to maximize the company's profit p?

Now ray has had the tires for two months and he notices that the tread has started to pull away from the tire. he has already contacted the place who sold the tires and calmly and accurately explained the problem. they didn’t him because they no longer carry that tire. so he talked with the manager and he still did not get the tire replaced. his consumer rights are being violated. pretend you are ray and write a letter to the company’s headquarters. here are some points to keep in mind when writing the letter: include your name, address, and account number, if appropriate. describe your purchase (name of product, serial numbers, date and location of purchase). state the problem and give the history of how you tried to resolve the problem. ask for a specific action. include how you can be reached.
