The equation of the line that passes through the points (2,1) and (5,-8) is
y = -3x + 7
Answer:
369
Step-by-step explanation:
g(f(x)) simply means to put the whole expression of function f(x) into the place of "x" in g(x).
and to find the functional value for a specific x we just need to calculate functional value for f(x) and use that result as input for g(x).
f(6) = 8×6 + 5 = 48 + 5 = 53
and now
g(53) = 7×53 - 2 = 371 - 2 = 369
to check we do the general functional substitution :
g(f(x)) = 7×(8x+5) - 2 = 56x + 35 - 2 = 56x + 33
g(f(6)) = 56×6 + 33 = 336 + 33 = 369
correct
Xy = 1 for all points.
We are going to demonstrate this affirmation:
(2) * (0.5) = 1
(1) * (1) = 1
(0.5) * (2) = 1
Therefore, the relationship between the ordered pairs is inverse.
The relationship between the ordered pairs is:
y = 1 / x
Answer:
xy = 1 for all points.
