Answer:
Y=-2
Step-by-step explanation:
You would use the vertex form to find the directrix
3/5t -4 -7/10t = -2 (as you know 3/5 = 6/10) so
6/10t - 4 - 7/10t = -2
Simplify
-1/10t -4 = -2
add 4 to both sides
-1/10t - 4 + 4 = -2 + 4
-1/10t = 2
multiply -10 to both sides
-1/10t *(-10) = 2 * (-10)
Simplify
t = -20
Answer first one t = -20
