Answer: the diameter is 7cm And the radius is 3.5 cm
Step-by-step explanation:
Answer: f^-1(4)= 2 f^-1(-5)= -4 f^-1(0)= 0
Step-by-step explanation:
The answer of your question is x - 4 y=8
Point slope form is:
y -

= m(x -

)
With

and

being the coordinate points, and m being the slope.
So the coordinate points are (4, -5), and the slope is -6 in this case.
So just substitute everything in, to get:
y - ( -5) = -6(x - 4)
Or
y + 5 = -6 (x - 4)
Answer:
x=-4
Step-by-step explanation:
x - 2x - 5 +4x = 7 + 6x
3x - 5 = 7 +6x
-3x -3x
-5 = 7 + 3x
-7 -7
-12 = 3x
-12/3= 3x/3
-4 = x
