Answer:
During his long political career, Franklin had extensive experience as a diplomat
Step-by-step explanation:
- - Step 1: Move the decimal point to the right, until you get greater then 1 and less than 10. In this case we moved it till we got 6.65.
- - Step 2: Count how many times you moved the decimal over: In this case, we moved it 4 times.
- - Step 3: All you have to do now is chose which one has 6.65 over -4.
(We are saying negative because when you move it to the right, it becomes negative.)
Final answer: A
-2m-9 is the simplified expression
Choice B, a is equal to c and b is not equal to d
Given the system of equations below:

The first equation is y-isolated so we can substitute in the second equation.

Use the distribution property to expand in and simplify.

The another method is to divide the second equation by 2.

Arrange in the form of y = mx+b.

When we finally arrange, compare the equation to the first equation. Both equations are the same which mean that both graphs are also same and intersect each others infinitely.
For more information, when the both sides are equal for equation - the answer would be infinitely many. If both sides aren't equal (0 = 4 for example) - the answer would be none. If the equation can be solved for a variable then it'd be one solution.
