Answer:
F(m) = -12
Step-by-step explanation:
Given the function:
When m = 4, we substitute the variable 'm' for the number 4:
F(m) = 256 - 384 + 80 + 40 - 4
F(m) = -12

Answer:
B.y increases as x increases.
Step-by-step explanation:
We are given that a graph.
We have to find the relationship between x and y.
From given graph, we can see that
The line is passing through the origin.
It means when x=0 then y=0
Direct proportional: It states that
It means when x increases then y also increases.
When x decreases then y also decreases.
Inversely proportional:It states that
When x increase then, the value of y will decreases.
When x decreases then, the values of y will increase.
We can see that from given graph, when x increases then, the values of y is also increases.
When x decreases then, the value of y also decreases.
Therefore, x is directly proportional to y.
Hence, option B is true.

The equation of c is an illustration of subject of formula
The equation of c in terms of r and t is c = r - 15/t
<h3>How to determine the equation?</h3>The equation is given as:
t = 15/(r - c)
Cross multiply
t(r - c) = 15
Divide both sides by t
r - c = 15/t
Subtract r from both sides
-c = -r + 15/t
Multiply both sides by -1
c = r - 15/t
Take LCM
Hence, the equation of c in terms of r and t is

The vector PQ is Q-P = (2, 1). The vector SR is R-S = (2, 2). One is not a multiple of the others, so the vectors are not parallel. In a parallelogram, these vectors would be identical. PQRS is not a parallelogram.
