Answer:
7) (f+g) (x) = 4^x + 5x -5
8) (f-g) (x) = 4^x + x - 5
Step-by-step explanation:
7) Find (f +g)(x)
(4^x + 3x + 2x - 5)
(4^x + 5x -5)
(f+g) (x) = 4^x + 5x -5
8) Find (f-g)(x)
(4^x + 3x - 2x - 5)
(4^x + x - 5)
(f-g) (x) = 4^x + x - 5
Answer:3(x-9) is expressed as 3x-27
Step-by-step explanation: 3(Xminus9)
3(X-9)
Use 3 to open the bracket by using 3 to multiply everything in the bracket.
Then you will get
3x-27
Descent time: 4.25 min
hover time: 12.75 min
19.125 - 4.25-12.75 = 2.125 min
So, the ascent rate was (-28.9 - (-79.9))ft/2.125min = 24.0 ft/min
A = false
b = true
c = true
d = true
Answer: 3 , 4 , 5 and 6
Step-by-step explanation:
Let the consecutive integers be ; x , x+1 , x + 2 and x + 3 , then their sum implies :
x + (x + 1 ) + (x + 2 ) + ( x + 3 ) = 18
x + x + 1 + x + 2 + x + 3 = 18
4x + 6 = 18
4x = 18 - 6
4x = 12
x = 3
Therefore , the numbers are
3 , 3 + 1 , 3 + 2 and 3 + 3
which are :
3 , 4 , 5 , 6
