Answer:
Step-by-step explanation:
Hence,
The value of (f - g)(x) is -x - 14
<h3>How to evaluate the function?</h3>
The given parameters are:
f(x) = 4x - 8
g(x) = 5x + 6
To calculate (f - g)(x), we make use of
(f - g)(x) = f(x) - g(x)
So, we have:
(f - g)(x) = 4x - 8 - 5x - 6
Evaluate the like terms
(f - g)(x) = -x - 14
Hence, the value of (f - g)(x) is -x - 14

Answer:
a) r ⋀~p
b)(r⋀p)⟶q
c) ~r ⟶ ~q
d) (~p ⋀r) ⟶q
Step-by-step explanation:
To solve this question we will make use of logic symbols in truth table.
We are told that;
p means "The user enters
a valid password,”
q means “Access is granted,”
r means “The user has paid the
subscription fee”
A) The user has paid the subscription fee, but does not enter a valid
password.”
Fist part of the statement is correct and so it will be "r". Second part of the statement is a negation and will be denoted by ~p. Since both statements are joined together in conjunction, we will use the conjuction symbol in between them which is "⋀" Thus, we have; r ⋀~p
B) Still using logic symbols, we have;
(r⋀p)⟶q
⟶ means q is true when r and p are true.
C) correct symbol is ~r ⟶ ~q
Since both statements are negation of the question. And also, if ~r is true then ~q is also true.
D) Similar to answer A to C above, applying similar conditions, we have (~p ⋀r) ⟶q
<span>Cylinder Volume = </span><span>π <span>• r² • height
height = </span></span><span>Cylinder Volume / (PI * radius^2)
</span><span>height = 500 cubic inches / 3.14159 * 16
</span><span><span><span>height = 9.9471839432
</span>
</span>
</span>
<span>height = 9.95 (rounded)
</span>
4 = 4x (original equation)
4/4 = 4x/4 (divide both sides by 4)
1 = x (simplify)
Make sure that you're doing the same things to each value on BOTH sides. This keeps the equation true. Once you do that, you should get that x is equal to 1.
