Let y=4x-1
The inverse is basically expressing x in terms of y.
y=4x-1 =>
y+1=4x
x=(y+1)/4
Since the inverse is still a function of x, we only have to interchange x and y
inverse of f(x) = f^-1(x) = (x+1)/4
Answer:
the line is going to be negative
start the line on (4, -2) so you know the line will contact the point
make sure the slope is -3
i dont know how else to help
Step-by-step explanation:
Looks like it's already in slope-intercept form.
slope-intercept form: y = mx + b
in this case, m is 8 and b is 4
HOPE it helps!!!!!!!!!
plz mark as a brainliest answer!!!!!!
The cost of one roll of plain wrapping paper is $8 and one roll of holiday wrapping paper is $14.
Step-by-step explanation:
Let,
Cost of one plain wrapping paper = x
Cost of one holiday wrapping paper = y
According to given statement;
6x+y=62 Eqn 1
3x+10y=164 Eqn 2
Multiplying Eqn 2 by 2

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 19

Putting y = 14 in Eqn 1

Dividing both sides by 6

The cost of one roll of plain wrapping paper is $8 and one roll of holiday wrapping paper is $14.
