Step-by-step explanation:
Hey there!
Given;
f ( x ) = x² + 2x - 1
g ( x ) = 3x - 2
To verify:
LHS:
~ Insert "2" instead of "x".
Simplify it;
Therefore; (f/g)(2) = 7/4.
RHS:
~Insert "2" instead of"x".
Simplify it.
Therefore, f(2)/g(2) = 7/4.
Since (f/g)(2) = f(2)/g(2) = 7/4.

A. the graph represents a relation because it contains ordered pairs (x,y). It is also a function because there are no repeating x values.
B. (0,0) (8,6)
slope = (6 - 0 ) / (8 - 0) = 6/8 = 3/4
so ur equation is : y = 3/4x or f(x) = 3/4x <===
C. the variable x represents the height of the building and the variable y (or f(x)) represents the total length of the shadow
F(x) = 1 - x
f(-3) = 1 - (-3)
f(-3) = 4
Answer: Hello, Here you Answer......
132 km
Given that the relationship between kilometers and fuel is proportional, let the distance in km be k and the fuel be f:
thus:
kα cf
k=cf
where k is the constant of proportionality. Thus:
c=k/f
Pamela drove 99 km and used 9 liters;
∴k=99/9=11 km/liter
therefore distance covered is given by:
k=11f
hence the distance covered with 12 liters of fuel will be:
k=11×12
=132 km Hope this helps! (Brainly)♥

Answer:
D. y = ±√(25 -x²)
Step-by-step explanation:
Subtract x² and take the square root to solve for y.
x² +y² = 25 . . . . . . . given
y² = 25 -x² . . . . . . . . subtract x²
y = ±√(25 -x²) . . . . . take the square root
