Answer:
I would say 100 since 256.78 is closer to 100 then 1000 or 10
Step-by-step explanation:
Are you working with simple interest?
The expression which can be used to determine the algebraic sum of the given polynomials as in the task content is; -11x² +4x +14.
<h3>Which expression can be used to find the sum of the given polynomials?</h3>
It follows from the task content that the polynomials whose sum are to be determined are; (9 - 3x2) + (-8x2 + 4x + 5).
Hence, the sum can be evaluated as follows;
= 9 - 3x² + -8x² + 4x + 5
= -11x² +4x +14.
Consequently, the required expression is; -11x² +4x +14.

The rate of change of the linear function represented by the table is 3
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The standard linear equation is in the form:
y = mx + b
Where m is the rate of change and b is the y intercept.
From the table, using the point (0, -7) and (2, -1):
m = [-1 - (-7)] / (2 - 0) = 3
The rate of change of the linear function represented by the table is 3
