Answer:
The sum is
.
Step-by-step explanation:
Consider the provided information.
The given expression are - 10t and t - 10t
We need to find the sum of the opposite of -10 t and t - 10t.
The opposite of -10 t is 10 t.

Remove the parenthesis.

Simplify the number

Use Additive inverse.

Hence, the sum is
.
Answer: A dependent system of equations
Step-by-step explanation: A dependent system of equations is when the same line is written in two different forms so that there are infinite solutions. These two situations occur when trying to solve for a system of equations. ... First a system of equations is called Inconsistent if there is no solution because the lines are parallel.
6.2, 7.0
To find the common difference between two outputs you will subtract the current output number from the proceeding number. Ex 5.4 - 4.6 = 0.8 and 4.6 - 3.8 = 0.8. Because they are the same value it means the function increases at a rate of 0.8 for each input of a.
so 5.4 + 0.8 = 6.2
and 6.2 +0.8 = 7.0.
