Answer:
Solving the system of equations:
x: 1
y: 2
Step-by-step explanation:
Plug it in to see if it is right, to make sure of course. Better to be safe than sorry.
Answer:
x is any integer except for -1
Step-by-step explanation:
If you substitute -1 for x, the denominator value would be 0, or undefined.
For this reason, x cannot be -1, which is mathematically known as an extraneous value.

Answer:
1st option
Step-by-step explanation:
to find f(g(x)) substitute x = g(x) into f(x) , that is
f(g(x))
= f(4x - 5)
= 2(4x - 5) + 1 ← distribute parenthesis
= 8x - 10 + 1
= 8x - 9
This is a geometric sequence of the form:
a(n)=ar^n, a=initial value, r=common ration, n=term number, if we relabel it for h(b) we have
h(b)=14(0.8^b)
h(3)=14(0.8^3)
h(3)≈7.2 ft (to nearest tenth of a foot)
