Question

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

Answer 1

Step-by-step explanation:

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