Is the question mark + or -. If it’s plus the answer would be 16 if it’s minus the answer would be 10.
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:
y = -1/2x +5
Step-by-step explanation:
The perpendicular slope will be the negative reciprocal of the original slope
the reciprocal of 2 is 1/2, and the negative of that is -1/2
Answer:
4x - 12
Step-by-step explanation:
8-4(-x+5)
Distribute
8 - 4*-x -4 * 5
8 +4x - 20
Combine like terms
4x - 12
Answer:
y=mx+b
Step-by-step explanation:
The slope-intercepts formula, the y = y coordinate, m = slope, x = x coordinate, b = y intercept
