Hey there!
Solve for X
x(2y - z) Factor out the variable x
x(2y - z)/2y - z = 4/2y - z Divide both sides by 2y - z
x = 4\2y - z
Hope this helps!
Answer:
3
Step-by-step explanation:
The f^-1 notation indicates you need to find the inverse of the function
y=2x+1
x=2y+1
Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x
7=2y+1
-2y=1-7
-2y=-6
Divide both side of the equation by -2
negative divide negative is positive so
y=3
Answer:
2n-3
Step-by-step explanation:
n represents the number of hours Darcy practices.
The number of hours Hannah practices each week is 3 hours less than twice the number of hours Darcy practices.
Twice the number of hours Darcy practices is 2n.
Hannah practices for : 2n-3
Hence, the expression that represents the number of hours Hannah practices is "2n-3".
radius is the distance from the centre of a circle to any given point on its circumference, diameter is the length between two points that are the furthest possible from each other on the circle's circumference.
The diameter is twice the radius.
Therefore, if the radius is 12in then the diameter is 24in.
