Answer:
f(-1) = 2
f(0) = 3
Step-by-step explanation:
f(a) = 3a - a²
f(4)= 3*4-4²= -4 ⇒ correct
f(3)= 3*3-3²= 0 ⇒ correct
f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect
f(0) = 3*0-0²= 0 ⇒ incorrect
f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct
Answer:
the capacity of the airplane be 200 passengers
Step-by-step explanation:
According to the question, the data provided is as follows
Number of passengers in an airplane = 180
Capacity = ![\frac{9}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B10%7D)
Based on the above information
Let us assume the capacity of the airplane be x
So the equation would be
![\frac{9}{10} \times x = 180\\\\\\x = \frac{1,800}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B10%7D%20%5Ctimes%20x%20%3D%20180%5C%5C%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B1%2C800%7D%7B9%7D)
So x = 200
Therefore the capacity of the airplane be 200 passengers
We simply applied the above equation so that the capacity of the airplane could come
Answer:
y=1/2x
Step-by-step explanation:
m=1/2
y=mx+b
-1=1/2*-2+b
-1=-1+b
b=0
y=1/2x
Answer:$825. 00
Add $25.+50. For week 1 then add $25.each additional week for 6weeks.
Step-by-step explanation:
Given the equation: f(p) = 1000p
Since: p = number of days = 150
Then f(p) would be the amount that the house was sold for after being on the market for "p" days. Applying that p = 150; then f(150) means that the house was sold for $150,000 after being on the market for an average of 150 days.
So the answer is 150
