First of all, remember if 2 people are walking away from each other at the same speed (ex 4 mph), after 1 mile, they would be 8 miles away. 4 miles south and north. So these trains go away from each other at a total of 150 mph( 67 + 83). So your equation is h = hours, 150h = 600. Divide both sides by 150 to get h = 4. 4 hours is your answer.
2.) No correlation
3.) Negative correlation
Step-by-step explanation:
(4,-5) i think because its asking for the function
From the equation, the slope is 2.
Point slope form: y - y1 = m(x - x1)
y + 1 = 2(x + 1)
Hope This Helped! Good Luck!
Plug in the expressions where the letters say for example the first problem would be set up as “4( x-5 )- 4( 2x+5 ). distribute and solve the equation.
