Answer:
Please see below.
Step-by-step explanation:
f^-1 (x) essentially means the reverse.
We can substitute y for x in the equation and solve for y:
x = 4y -1
x+1 = 4y
y = (x+1)/4
so that is our answer for the first one:
f^-1(x) = (x+1)/4
We do the same trick for the second question:
x = 2y +1
x-1 = 2y
y = (x-1)/2
so the answer is f^-1(x) = (x+1)/2
The last question is slightly more complex, we can write is as:
x = 2y/(y-1)
x(y-1) = 2y
yx -x = 2y
yx = 2y + x
yx - 2y = x
y(x-2) = x
y = x/(x-2)
so the answer is x/(x-2)

0.7 is larger because the 7% which mean 7 divide 100 is 0.07
So, 0.7 is larger
Answer:
The statement is true
The lines are perpendicular
Step-by-step explanation:
we have
----> equation A
The equation A represent a vertical line (is parallel to the y-axis)
The slope is undefined
----> equation B
The equation B represent a horizontal line (is parallel to the x-axis)
The slope is equal to zero
Remember that
The y-axis and the x-axis are perpendicular lines
so
Line A and line B are perpendicular lines too
therefore
The statement is true
Answer:
dilated
Step-by-step explanation:
In a dilation, angle measures are preserved but not side lengths. Similar figures are not necessarily congruent, and its a given that the image is similar to the pre-image so it has to be option b
1. Option B - triangle DEF
2. Option A - (0,5)
3. Option C - they all move one unit up
4. Option A - triangle ABC
5. Option B - triangle DEF
6. Option A - Vertical
7. Option C - (4,1)
8. Option B - (5,1)
9. Option B - Its Larger
10. Option A - (2,2)
