Answer:
The two values of x are -2.5 and -3
Step-by-step explanation:
we have
![2x^{2}+11x+15=0](https://tex.z-dn.net/?f=2x%5E%7B2%7D%2B11x%2B15%3D0)
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
substitute in the formula
therefore
The two values of x are -2.5 and -3
Answer:
The correct option is A,3875 passengers
Step-by-step explanation:
The curve of best fit for the date y=-5x^2+60x+3715
For April which month 4 which means that x is 4
By substituting 4 for x in the equation we can determine y, the number of passengers that arrived on flights at the airport is determined thus.
y=-5*4^2+(60*4)+3715
y=-5*16+240+3715
y=-80+240+3715=3875
The number of passengers that arrived by flights in April, month 4 is 3875
<span><span> x =(11-√137)/2=-0.352</span><span> x =(11+√137)/2=11.352</span></span>
Answer:
you started with 6 candies
Step-by-step explanation:
find the sum if 1/2 and 1/4 of the remaining half
1/2+1/4=3/4
therefore 3/4 of the candies has been eaten remaining 1/4 of the candies.
total fractions of candies =1
if 1/4 : 3
then 1: ?
if more, less divides
1÷1/4×3
1×4/1×3
12
there fore the total candies are 12 and since the question asked his much you started with, and you know you started with half of the total, find half of the total
1/2×12=6
