Equation 1: x + 2y = 10 equation 2: 2x + 5y = 15 step 1: −2(x + 2y) = −2(10) 2x + 5y = 15 step 2: −2x − 4y = −10 2x + 5y = 15 step 3: 1y = 5 step 4: x + 2(1) = 10 step 5: x = 8 in which step did the student first make an error? (4 points) a)step 1*i think its this one b)step 2 c)step 3 d)step 4

Will mark brainliest with 20 points! the table shows how far object 1 traveled as a function of time. *time (seconds) - 2 4 6 8 *distance traveled (feet) - 18 36 54 72 the equation shows how far object 2 traveled in feet as a function of time in minutes. *f(x) = 10x which object traveled at a faster speed? justify your response.
