you can do 25 minus 18.76 then you get 6.24 then divide that by .13 and you get 48
One as it intersects only on the Y axis
Answer:
y=1/3x + 2
Step-by-step explanation:
the y intercept is 2 since that's where the line crosses and the x intercept is at 4
Answer:
f⁻¹(x) = (1/2)x +5
Step-by-step explanation:
In y = f(x), swap the variables, then solve for y. The expression you get is f⁻¹(x).
... y = 2x -10
... x = 2y -10 . . . . . . swapped variables
... x +10 = 2y . . . . . add 10
... (1/2)x + 5 = y . . . . divide by 2
... f⁻¹(x) = (1/2)x + 5 . . . . . . rewrite using function notation
