Question 15 Yesterday morning. Sammi traveled from his house to the library, which is a distance of 1.5 miles. He traveled to the library as follows: • For the first 0.5 miles, Sammi ran at a pace of 1 mile per 10 minutes,
• Sammi then stopped for 10 minutes and rested.
• He then walked at a pace of 1 mile per 20 minutes until he arrived at the library,

it says for me to graph it out so if u can get me a graph going by 10s thatd be great. i dont understand this​

{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

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1

the answer to this is a. a^2 + b^2 = c^2

i think it’s a i believe
