Your right on both of your answers to number 1 and 2
Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
y =2x+3
Exchange x and y
x = 2y+3
Solve for y, subtracting 3 from each side
x-3 = 2y+3-3
x-3 =2y
Divide each side by 2
(x-3)/2 = 2y/2
1/2x - 3/2 =y
The inverse is 1/2x -3/2
5 - substitute the numbers 1-10 for n in (3n-4) and add up all your answers. So (3(1)-4) + (3(2)-4)...
