Answer: D) (-5, 1)
<u>Step-by-step explanation:</u>
Inverse is when the x's and y's are swapped.
f(x) has the coordinate (1, -5) --> the inverse of that is (-5, 1), which is option D.
Answer: -21/2
Concept:
Usually, when doing mathematics operation, it goes by the PEMDAS order:
- Parenthesis
- Exponent
- Multiplication
- Division
- Addition
- Subtraction
However, since the question asks to solve the order of operation from left to right, then we would be doing [addition] --> [Divison]
Solve:
<u>Given</u>
(-5/2) + 3/4 ÷ 1/6
<u>Operate with addition</u>
=(-10/4) + 3/4 ÷ 1/6
=(-7/4) ÷ 1/6
<u>Operate with division</u>
=(-7/4) × 6/1
=-42 / 4
=-21 / 2
Hope this helps!! :)
Please let me know if you have any questions
-2x = 4x + 9 Subtract 4x from both sides. -6x = 9 Divide both sides by -6. x = -9/6 Simplify the fraction. x = -3/2 Now, oh can check your answer by plugging it into the equation. -2(-3/2) = 4(-3/2) + 9 Multiply. 3 = -6 + 9 Add 3 = 3. So, x = -3/2.
There still under the thousands place... It's just the bigger the number gets the smaller the value is...
Example:
.3453 it's less than .23
Because .3453 is bigger than .23 but the value makes it smaller if that makes since
For either square root to exist, you require that
. This is true for all
, since
is always non-negative. This means the domain of
as a function of
is all real numbers, or
or
.
Now, because
is non-negative, and the smallest value it can take on is 7, it follows that the minimum value for the positive square root must be
, while the maximum value of the negative root must be
. This means the range is
, or
, or
.
