Answer:
Choice B and Choise C.
Step-by-step explanation:
Equivalent expressions are those expressions that have the same value but they look different.
Given the following expression provided in the exercise:
You need to remember the multiplication of signs in order to find the equivalent expressions:
Then:
- Eliminating the parentheses, you get this equivalent expression:
- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:
This is an equivalent expression to
Answer: The change is -25 dollars so she currently has 325 dollars
Step-by-step explanation:
Given:
radius of cone = r
height of cone = h
radius of cylinder = r
height of cylinder = h
slant height of cone = l
Solution
The lateral area (A) of a cone can be found using the formula:
where r is the radius and l is the slant height
The lateral area (A) of a cylinder can be found using the formula:
The ratio of the lateral area of the cone to the lateral area of the cylinder is:
Canceling out, we have:
Hence the Answer is option B
Answer:
The equation would be Y=-1/4X+5
And in the above pic , i have graph the line , too .
Good luck ^.^
If you are working with time or days, you can't put in a negative value because if you are doing an experiment, you can't go back in time to do that experiment to gather data. (Time for the most part considered to be an input value so that's why I used it as an example.)
