Step-by-step explanation:
Answer:
t≤ 8/5
Step-by-step explanation:
-4t≥-2/5 (at last means greater than or equal to }
multiplying by -1
when we multiply or divide by negative number sign of inequality changes
4t≤2/5
t≤4(2/5)
t≤ 8/5
Answer:
Step-by-step explanation:
Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
- that's how you find the vertex of the quadratic function-
