Answer:
x = 4.9t²
Step-by-step explanation:
x is directly proportional to t²
x = kt²
When t = 2 , x = 19.6
Substitute into the equation
x = kt²
19.6 = k * 2²
19.6 = k * 4
19.6 = 4k
k = 19.6/4
k = 4.9
Substitute the value of k into the equation:
x = kt²
x = 4.9t²
Answer: There is no solution.
Step-by-step explanation:
1.) 1 / 5 (25) + 1 / 5 (-5a) = 4 - a
2.) 5 - a = 4 - a
3.) 5 - a + a = 4 - a + a
4.) 5 = 4
The variable a is completely removed, leaving the final answer as 5 = 4, which isn't true.
