you change the y to have it y=3x+16 and same with the other one i think
M = y2 - y1 / x2 - x1
= - 9.75 - 6.75 / 3.33 - ( -8.5 )
= - 16.5 / 11.83
=> y= - 16.5 / 11.83x +b
6.75 = - 16.5 / 11.83 ( -8.5) +b
6.75 = 11.86 +b
=> b = - 5.11
Answer : y= - 16.5 / 11.83x - 5.11
OK so to solve this we will subtract 16x from 2x to get -14x
-14x - 4y + 3x^2 + 7y
add - 4y and 7y to get 3y
-14x + 3x^2 +3y
and then to simplify we are going to move the -14x
3x^2 +3y - 14x
The exact distance she drove was 236.39 miles
61.4 miles per hour x (times) 3.85 hours = 236.39 miles in total
Answer:
$175
Step-by-step explanation:
$100/8 hours = $12.5 hourly
$12.5 * 14 hours = $175
