Answer:
the inverse is 9x + 18
Step-by-step explanation:
switch 'x' with 'y'
y = 1/9x - 2
x = 1/9y - 2
solve for y now, start with multiplying each side by 9
9x = y - 18
y = 9x + 18
f^-1(x) = 9x + 18
Yes, you have the right answer for part 1.
But for the second part it should be A. Because if it is a square, it has to be both a rectangle and a rhombus, that is the only way to prove it.
We know it is a rhombus because we are given a right angle. And rhombus' diagonals are the perpendicular bisector of each other. we know the diagonals are both perpendicular bisectors because the segments divided are congruent, and it created a right angle. Therefore, it is a rhombus.
We know it is a rectangle because we know rectangles' diagonals are congruent. We can see all four segments are congruent, so "if congruent segments are added to congruent segments, then the sum is congruent". So the diagonals are congruent, showing it is also a rectangle.
So when a figure is both a rectangle and a rhombus, it is a square.

See explanation
Step-by-step explanation:
In this problem,, we are told that Mr Nelson needs 5 1/2 yards of fabric to make two dresses. the problem then asks us to find out how much fabric it will take to make only one of the dresses. this means that in order to find out how much fabric is needed to make only one of the two dresses,, we need to divide the total amount of fabric by two. the equation will look like the following:
5 1/2 ÷ 2
the first step to solving this is to convert the mixed number to an improper fraction
11/2 ÷ 2
now,, you can turn the 2 into a fraction and changed the sign because dividing is equivalent to multiplying with the reciprocal value.
11/2 × 1/2
you must then multiply the fractions
11/4
finally,, you need to simplify the fraction to find the answer
2 3/4 yards
since you cannot simplify any further,, the correct answer to your question is A, 2 3/4 yards.
let me know if you have any further questions
