The correct answer of 1/3 is the decimal form of it which is 0.3 repeated (you can put a line on top of the 3). If not just leave it as 1/3 it is simplified as a fraction.
Answer:
The answer is actually <em>CD, GH, and AB</em>. I got it incorrect from the answer above. This is for people in the future who are looking for answers and don't get messed up over that guy.
Step-by-step explanation:
I just took the test and got the answer wrong. Correct answer above. (Checkmarks next to answer means its correct)
Answer:
Inverse of y =
=
.
Step-by-step explanation:
Given : f(x) = y = 100 - x²
To find : Find inverse.
Solution : We have given that :
f(x) = y = 100 - x²
Step1) : Replace every x with a y and replace every y with an x .
x = 100 - y².
Step 2): Solve for y
On subtracting 100 from both sides
x - 100 = -y²
On multiplying both side by -1
100 -x = y²
Taking square root both sides and switching sides
y = ±
.
Step3 ) : Replace y with
.
= ±
.
Therefore, inverse of y =
= ±
.
Step-by-step explanation:Create equivalent expressions in the equation that all have equal bases.
2
x

3
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
x

Move all terms not containing
x
to the right side of the equation.
Tap for fewer steps...
Add
5
to both sides of the equation.
x

Add
3
and
5
.

8
The denominator must be the same, so just think of the LEAST COMMON MULTIPLE, The LCM here is 8, because you can multiply 4 by 2 to get 8.
so when you multiply, you multiply both on the top and on the bottom, so this would be:
3 x 2 / 4 x 2 = 6 / 8
Now you can add or subtract: 6/8 - 1/8 = 5/8
