Answer:
f^-1(x)=x-3/2
Step-by-step explanation:
we have f(x)=2x+3
let
y=f(x)
y=2x+3
Exchanges the variables x for y and y for x
x=2y+3
isolate the variable y
2y=x-3
y=x-3/2
let
f^-1(x)=y
f^-1(x)=x-3/2
Answer:
Step-by-step explanation:
The answer is B on Edgenuity
f^-1 (x) = 1/2x - 3/2

Which set of ordered pairs represents a function?
O {(-4,9), (-4,7), (1, -5), (7, -8)}
{(-5, -5), (-9,1), (8,-6), (-9,-4)}
{(-6, -6), (-2,-2), (7,-6),(-5,0)}
{(-7, -9), (-7, -7), (3,-7), (5,-5)}
Submit Answer
Answer: {(-6, -6), (-2,-2), (7,-6),(-5,0)}
Step-by-step explanation:
To find the ordered pairs that represent a function, we want to find one that doesn't have multiple outputs for one input.
{(-6, -6), (-2,-2), (7,-6),(-5,0)} is the correct answer because all the x are different, and have only one output.
how to change a bianary number into decimal number
1. Positional Notation
2. Doubiling
3. An Online Converter
Step-by-step explanation:
Hey there!!!
We generally multiply using base 2 and keep power that starts from 0 and goes on increasing and add all them at last to convert binary to decimal.
For example:
011110
To convert into decimal follow the steps.
1st step: Multiply with base 2 and keep power from right side starting from 0.
[tex]0 \times {2}^{5} + 1 \times {2}^{4} + 1 \times {2}^{3} + 1 \times {2}^{2} + 1 \times {2}^{1} + 0 \times {2}^{0} [/tex]
2nd step: solve powers and multiply with binary numbers.
This implies;
= 0 + 16 + 8 + 4 + 2 +0
= 30.... is your answer.

If my answer helps you, please give me a brainliest! thanks.
If Aaliyah spent $32.30, she brought 19 chicken wings.
What is division in mathematics?One of the four fundamental operations in mathematics is division, along with addition, subtraction, and multiplication. The splitting of a large group into smaller groups so that each group contains an equal number of items is a straightforward definition of division. It is a mathematical process used for equitable grouping and distribution.
Aaliyah bought 23 chicken wings for $39.10.
Hence, as the price of each chicken wings is same, the price of each chicken wings will be= $39.10÷23 = $ 1.70
She spent $32.30 in buying chicken wings.
So, The number of chicken wings, she got = $32.30/$1.70 = 19.
Hence, if Aaliyah spent $32.30, she brought 19 chicken wings.
