Answer:
Step-by-step explanation:
If we are given the quadratic model, we know that the height of anything on the ground is 0 meters, so that model becomes
I changed your x's to t's since t is for time.
Now we need to factor that quadratic and solve for time:
Since -2 definitely does not equal 0, then
Factor that and find t values of 4 and -2. Again, we know that time will never be negative, so
t = 4 seconds.
Answer: B
Step-by-step explanation:
To isolate x, you divide both sides by 21
21x=7
x = 7/21
Simplify by dividing both the numerator and denominator by 7
x = 1/3
Since, 1/3 is not an option, B is the correct answer
$470-45+160-500= $630-545= $85. Logan still owes $85 :)
