Substitute -x-5 for y
Gets you:
3x-2(-x-5)
Distribute the 2
3x-(-2x-10)
Distribute the -1
3x+2x+10
Combine like terms
5x+10
Subtract 10 from both sides
5x=-10
Divide by 5
x = -2
Answer:
1, 2, 3, 5
Step-by-step explanation:
I took the quiz
The fourth vertex would be at (2,5).
It has to be the same x value as (2,3) and the same y value as (-6,5)
! means factorial, if you did not already know. It means multiply together all the numbers leading up to that number. For example, 4! = 4x3x2x1 = 24
Evaluate means just solve it.
9! = 9x8x7x6x5x4x3x2x1 = 362880
5! = 5x4x3x2x1 = 120
362880 - 120 = 362760
There is your answer
