Answer:
Please check the explanation.
Step-by-step explanation:
Given
a)
f(x) + g(x) = (2x - 1) + (2 - x)
= 2x -1 + 2 - x
= x + 1
b)
f(x) - g(x) = (2x - 1) - (2 - x)
= 2x - 1 - 2 + x
= 3x - 3
c)
g(-5) - f(-5)
Putting x = -5 in g(x) = 2 - x
g(x) = 2 - x
g(-5) = 2 - (-5) = 2+5 = 7
Putting x = -5 in f(x) = 2x - 1
f(x) = 2x - 1
f(-5) = 2(-5) - 1
= -10 - 1
= -11
Thus,
g(-5) - f(-5) = 7 - (-11) = 7+11 = 18
d)
f(x).g(x) = (2x - 1) (2 - x) = -2x² + 5x - 2
e)
f(g(x)) = f(2-x)
= 2(2-x)-1
= 4-2x-1
= 3-2x
Answer:
less
Step-by-step explanation:
first you would multiply and get 4/8, which simplifies to 1/2, which would be 2/4, which is less than 3/4
Answer:
I think its 1 1/3 or 1.333
Step-by-step explanation:
divided 16 by 12 bc 12 divided by 12 makes the 1
Step-by-step explanation:
(x, y) is a solution to y = 5/2X
(x, y) is a solution to y=x+3.
The ratio of Y/X is equivalent to 5/2
Point (x, y) is the same point as (5, 2).
A straight line through points (2, 5) and (x, y) will pass through the origin.
