GIVING BRAINLIST Cassie is traveling 675 miles today to visit her brother and his family. So far, she has stopped for gas three times. At the first stop, she put in 7.1 gallons of gas and paid $23.79. At her second stop, she put in 5.8 gallons of gas and paid $19.08. And, at the third stop, 6.6 gallons and paid $20.39. If the gas station that Cassie stopped at first raises their price 8%, what will be their new price per gallon to the nearest cent?

$3.62

answer: the answer is 127 degrees

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
