Answer:
2
Step-by-step explanation:
When the input is -1 ( the x value is -1) what is the the output ( what is the value of y)
Using the graph, we got to x =-1 and go up and find y =2
When the input is -1 the output is 2
The number of possible outfits would be 168 outfits. YOu can mix and match up to 168 number of outfits from these set. This is an example of counting principle. In this principle, one event has n possibilities then a second independent variable have m outcomes. Then, the total possibilities would be n times m.
~ Simplifying
-2(7x + -5) = -14x + 10
~ Reorder the terms:
-2(-5 + 7x) = -14x + 10
(-5 * -2 + 7x * -2) = -14x + 10
(10 + -14x) = -14x + 10
~ Reorder the terms:
10 + -14x = 10 + -14x
~ Add '-10' to each side of the equation.
10 + -10 + -14x = 10 + -10 + -14x
~ Combine like terms: 10 + -10 = 0
0 + -14x = 10 + -10 + -14x
-14x = 10 + -10 + -14x
~ Combine like terms: 10 + -10 = 0
-14x = 0 + -14x
-14x = -14x
~ Add '14x' to each side of the equation.
-14x + 14x = -14x + 14x
~ Combine like terms: -14x + 14x = 0
0 = -14x + 14x
~ Combine like terms: -14x + 14x = 0
0 = 0
~ Solving
0 = 0
~ This equation is an identity, all real numbers are solutions.
