Answer:
The length of the first piece is 5 ft
The length of the second piece is 20 ft
The length of the third piece is 25 ft
Step-by-step explanation:
Let
x----> the length of the first piece
y ---> the length of the second piece
z ---> the length of the third piece
we know that
-----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A and solve for x
<em>Find the value of y</em>
<em>Find the value of z</em>
therefore
The length of the first piece is 5 ft
The length of the second piece is 20 ft
The length of the third piece is 25 ft
Answer: y=x³+2 or f⁻¹(x)=x³+2
Step-by-step explanation:
To find the inverse of the radical function, we replace y with x and x with y. Then, you solve for y.
[replace y with x and x with y]
[cube both sides to cancel out the cubed root]
[add both sides by 2]
Now that we have switched the variables and solved for y, we know that the inverse function is y=x³+2 or f⁻¹(x)=x³+2.
Answer:
thanks for the pts anyways
Step-by-step explanation:
If
|a|=b
assume
-a=b and
a=b
|3x-4|=5
assume
3x-4=5 and
-3x+4=5
solve each
3x-4=5
add 4
3x=9
divdide 3 both isdes
x=3
-3x+4=5
minus 4
-3x=1
divide -3
x=-1/3
x=-1/3 and 3
