I believe you meant - <span>16t^2 + 604 ft. If you leave that - sign out, this function will never equal 348 feet.
-16t^2 + 604 = 348 can be solved:
-16t^2 = -256 ft, and t = 16 sec. Whatever you are throwing will first rise, reach some max. value, and then begin falling, and eventually reach 348 ft.</span>
Answer:
Explanation contains answer.
Step-by-step explanation:
Question 1:
I would perfer to solve the first equation for y because there is only one operation to perform on both sides and it is subtraction of 2x on both sides.
The other equation requires two steps to isolate y; subtracting 3x on both sides then multiplying both sides by -1.
So basically solving the first one for y because it has coefficient 1.
Question 2:
They solved the 2nd equation for y and plugged into itself instead of plugging it into 1st equation.
