Answer:
10
Step-by-step explanation:
If there is a constant rate of change, its value will be ...
k = y/x
k = 250/25 = 10
The constant rate of change is 10.
y = 10x

Answer:
x^2 +23x +49
Step-by-step explanation:
First we find the area of the rectangle as though the small square were not cut out of it
A = (x+10) (2x+5)
Foil
2x^2 +5x+20x+50
2x^2 +25x+50
Then we find the area of the small square
A = (x+1) (x+1)
FOIL
x^2 +x+x+1
x^2 +2x+1
Then we subtract the small square from the large rectangle to find the area of the shaded region
2x^2 +25x+50 - (x^2 +2x+1)
Distribute the minus sign
2x^2 +25x+50 - x^2 -2x-1
x^2 +23x +49
Answer:
With regard to mathematics, an axiom is an accepted statement of fact that is used to prove other statements.
Step-by-step explanation:
As we know that an axiom - normally called postulate - is a statement which is considered to be true in order to serve as an initial point in order to establish further reasoning, from which we may be able to logically drive the other mathematical statements.
Therefore, with regard to mathematics, an axiom is an accepted statement of fact that is used to prove other statements.
