Substitute the f(x) and g(x) following the required operations:
A. (f+g)x = (x^2 + 1) + (x + 1) = x^2 + x + 2
B. (f-g)x = (x^2 + 1) - (x + 1) = x^2 - x
C. (fg)x = (x^2 + 1)(x + 1) = x^3 + x^2 + x + 1
D. (f/g)x = (x^2 + 1) / (x + 1) or x - 1 + 2/(x+1) if answer must be in expanded form
E. (f o g)x = (x+1)^2 + 1 = x^2 + 2x + 2
F. (g o f)x = (x^2 + 1) + 1 = x^2 + 2
Flower bed A:
circumference= 2 x pi x r= 2x pi x10/2
=10pi feet
Area= pi x r^2=25pi square feet
Flower bed B:
circumference=12 pi feet
Area=36 pi square feet
Answer:
6
Step-by-step explanation:
Multiply 40 by 15%, or 0.15.
So it goes as
8x+4y=16
7y=15-x
I want x by itself in the second equation so I subtracted 15 from both sides
7y-15=-x
I then divided each side by -1 to get
x=-7y+15
Now that I have x, I can plug that into the first equation to get:
8(-7y+15)+4y=16
Factor:
-56y+120+4y=16
Combine like terms and subtract both sides by 120
-52y=-104
Divide both sides by -52 to get y by itself
y=2
Therefore, the coordinates are (1,2) or C .
