Answer:
Step-by-step explanation: Substitute x-c for y in the ellipese equation. Then solve the resulting equation for x, with c as a remining unknown.
Pick the vaue of c that results in one value for x. That will correspond to the tangent-line situation.
hopefully this is right
Answer:
Stacy's rate is 18 miles over the last 2 hours
Step-by-step explanation:
On a bicycle, Stacy rides for 8 hours and is 74 miles from her house. After riding for 10 hours, she is 92 miles away
Let x be the number of hours and y be the number of miles
Stacy rides for 8 hours and is 74 miles , (8,74)
riding for 10 hours, she is 92 miles away (10,92)
To find the rate per hour we find slope

slope 18 divide by 2 represents 18 miles for every two hours
so Stacy's rate is 18 miles over the last 2 hours
X+2y=10
6x+6y=6 -> x+y=1
(x+2y=10)-(x+y=1)=y=9
x+(2*9)=10
x+18=10
x=-8 and y=9 -> c
