What you want to do is change the variable positions of X and Y
So it would be a new equation of
x = 1/2y + 3
Then you would need Y to be by itself so you solve for that
x-3 = 1/2 y
then,
2(x-3) = y
Your inverse function is 2(x-3) = y
Hope this helped :D
Answer:
We need to sell the nuts at 35 dollars to make $20 profit
Step-by-step explanation:
Profit = Selling price - cost
We know we want a 20 dollar profit
The cost of the nuts is 15 dollar
Substitute this in
20 = Selling price -15
Add 15 to each side
20+15 = Selling price -15+15
35 = Selling price
We need to sell the nuts at 35 dollars to make $20 profit
We know that
[scale]=1 in / 30 in
scale=measure in the drawing/measure in the actual
[measure in the actual]=measure in the drawing/scale
the measure in the drawing are
3 in x 4 in
so
for 3 in
measure in the drawing=3 in
[measure in the actual]=3/(1/30)-----> 3*30------> 90 in
for 4 in
measure in the drawing=4 in
[measure in the actual]=4/(1/30)-----> 4*30------> 120 in
the measure in the actual are
90 in x 120 in
1 ft----------> is equal to 12 in
x-------------> 90 in
x=90/12-----> 7.5 ft
1 ft----------> is equal to 12 in
x-------------> 120 in
x=120/12-----> 10 ft
the measure of a bedroom in feet are
7.5 ft x 10 ft
the area=7.5*10--------> 75 ft²
the answer is
<span>the area of the room is 75 ft</span>²
Answer:
"The values for y are square roots of negative numbers"
Step-by-step explanation:
The steps shown are correct. But at the end we can see that we have to <em><u>"take the negative square roots"</u></em>.
This means we have to take the square root of -1. In the real number system, we CANNOT take the square root of any negative number. Hence, there is NO SOLUTION to the system.
2nd answer choice, "The values for y are square roots of negative numbers", is right.
