Answer:
2(x-3) = y
Step-by-step explanation:
y = 1/2 x +3
To find the inverse, exchange x and y and then solve for y
Exchange x and y
x = 1/2y +3
Then solve for 3
Subtract 3 from each side
x-3 = 1/2 y -3+3
x-3 = 1/2 y
Multiply each side by 2
2 (x-3) = 1/2 *2 y
2(x-3) = y
This is the inverse
Answer:
median of given data is 18
Answer:
Step-by-step explanation:
6. Use PEMDAS
-3 x (7 + (-3)*2) / 3
-3 x (7 + 9) / 3
-3 x 16 / 3
-48 / 3
-16
7. 9 (x) = -63
X = - 63 /9
X = -7
