Answer:
Not a linear relationship
Step-by-step explanation:
Given
The attached table
Required
Linear or not
To do this, we simply calculate the slope of the table at different intervals.
Slope (m) is calculated as:

Let:


So, the slope is:




Let:
Let:


So, the slope is:




See that the calculated slopes are not equal.
Hence, it is not linear

The equivalent expression of 25
- 64 are "a), b) and c)".</h2>
Step-by-step explanation:
The given expression is:
25
- 64
To find, the equivalent expressions are:
a) 25
+ 40x - 40x - 64
= 25
- 64, is the equivalent expression.
b) 25
+ 13x - 13x - 64
= 25
- 64, is the equivalent expression.
c) (5
+ 8)(5
- 8)
Using the algebraic identity,
(a + b)(a - b) = 
= 
= 25
- 64, is the equivalent expression.
d) (
+ 13)(
- 13)
Using the algebraic identity,
(a + b)(a - b) = 
= 
=
- 169, is not a equivalent expression.
e) 
Using the algebraic identity,


, is not a equivalent expression.
∴ The equivalent expression of 25
- 64 are "a), b) and c)".
Answer:
THE ANSWER IS C
Step-by-step explanation:
Move all terms to the left side and set equal to 0. Then set each factor equal to 0.
The answer:
x = 4, -3/5
