Answer:
Step-by-step explanation:
I think its D if its not pls tell me so I can redo it.
If you use fractions, the answer you get will always be an exact answer in the form of a fraction. resorting to decimals means that you may run into rounding errors and therefore get only an approximate answer. e.g. the fraction 1/3 cannot be exactly represented by a decimal.fractions can be easier to represent the number rather then using decimals which involve writing out many numbers it does not affect the accuracy of the answer UNLESS you are rounding up and down the numbers
The discriminant is b^2-4ac
In this equation 9=a, 12=b, 4=c
Plugging into the formula
12^2-4(9)(4)=
144-324 =
-180 is the discriminant
Since the discriminant is a negative number there are no real roots
Answer:
x ≤ 75
Step-by-step explanation:
The computation of the inequality function is as follows:
Let us assume the remaining time left for other drills be x
Given that the team spends 20 minutes for running laps
And minimum of 15 minutes for discussing plays
Also practicing for last one hour and 45 minutes
Now as we know that
1 hour = 60 minutes
So total minutes would be
= 60 + 45
= 105 minutes
Total minutes spend by the team is
= 20 + 15
= 35 minutes
So now the remaining time left is
x ≤ 105 - 35
x ≤ 75
Answer:
Divide both sides by 5.
Step-by-step explanation:
Divide both sides by same non-zero constant.
