Answer:
50 degrees
Step-by-step explanation:
You know it's a right angle, so that means it is 90 degrees, just subtract 40 degrees from 90 since you know a = 40 and a+b=90
Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
Set the equation equal to y
y = 2x+3
Exchange x and y
x = 2y+3
Solve for y
Subtract 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
Answer:
176
Step-by-step explanation:
Answer:
-60.X + 32 = 32.r – 60
Because we only have one equation for 2 unknowns.
Step-by-step explanation:
All the equations have solution for r but the one that has 2 unknowns (r and X).
That is because we only have one equation and 2 unknowns.
Then, we only can express one unknown in function of the other and have an indeterminate solution.
