The expression is simply -2-18. When you have an expression like this, just put the together and the put a box around the first number don't forget the sign, and then the next put one around the sign and the number. If this doesn't make any since, sorry we just started this unit
Answer:
x = 14; y = 8
Step-by-step explanation:
A perpendicular intersection means an intersection between 2 lines, forming angles of 90°. Then:
7x - 8 = 90°
11y + 2 = 90°
7x - 8 = 90
7x = 90 + 8
7x = 98
x = 98/7
x = 14
11y + 2 = 90
11y = 90 - 2
11y = 88
y = 88/11
y = 8
I hope I've helped you.

M[n(x)] = 4(x - 10) - 11 = 4x - 40 - 11 = 4x - 55
