Answer:
31-3n
Step-by-step explanation:
d=-3
a1=28
an= 28+(n-1)(-3)=28-3n+3
an=31-3n
Answer:
x = 43
Step-by-step explanation:
3x - 31 = 2(x+6)
3x - 31 = 2x+ 12
x =43
I first found the slope of the line graphed. So i took 2 points and found the slope. They were (2,0) and (0,-3). The slope was 3/2. I then flipped it and added a negative because your looking for the perpendicular line. That was -2/3.
I took the formula y1-y=m(x1-x) and put in -2/3 as m and y1 as 2 and x1 as -1. You plug those into the equation and solve for y.
I got B for the answer
Hope this helps!
The answer would be A. Radical sign 3.
