Question

Which value of x would make the rate of change between the two points -5? (12,7) and (x,17)

Answer 1

Explanation:

`\sqrt{(12 - x) {}^(2) + {(7 - 17) {}^(2) } } = - 5\\ \\ \sqrt{144 + x {}^(2) - 24x + ( - 10) {}^(2) } = - 5 \\ \\ \sqrt{144 + x {}^(2) - 24x + 100} = - 5 \\ \\ 244 + x {}^(2) - 24x = 25 \\ \\ {?}^(2)`
