The Function is increasing over the interval : -2 ≤ x ≤ 3
<u>Proof </u>: The Slope should be Positive over this Interval
Let us Calculate the Slope of the Function at which the Function is increasing.
We can notice that the Increasing Function part is passing through the Points (-2 , -3) and (3 , 3)
We know that Slope is given by :
⇒
<u>As the Slope is Positive :</u>
The Function is increasing over the interval : -2 ≤ x ≤ 3
Well 6,250×2=12,500grams
1000 grams =1kg
So 12,500÷1,000=12.5kg
So your answer is 12.5 kg
Answer:
Step-by-step explanation:
P2 takes 45 min/procedure
P1 takes 22.5 min/procedure
For nine procedures,
Answer:
x = -9, y = -3.
As an ordered pair it is (-9, -3).
Step-by-step explanation:
Substitute x = 3y in equation 1:
2y + 3y = -15
5y = -15
y = -15/5
y = -3.
Now find x by plugging y = -3 in x = 3y:
x = 3*-3 = -9.
Check the answer in equation 1:
2(-3) + -9
= -6 - 9
= -15 Correct.
