Put the values of x = 4 and y = -2 to the expression 5y² + 3xy - 2x.
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right).
Answer:
if f(x) = ax + b then f-1(x) = (x - b)/a
Step-by-step explanation:
Now
f(x)=ax + b
then y = ax + b
interchanging x and y , we get
or, x = ay + b
or, x - b = ay
or, (x - b)/a = y
therefore,f-1(x) = (x - b)/a

Answer:
4
Step-by-step explanation:
The product of a number m and 4 is 16
=m×4=16
16÷4=4
To be able to identify if there is a remainder or not, you have divide and solve the problem and then check and see if you have any left over numbers.
Hope this helps and can I have brainliest answer!
