Answer:
f^-1 (x)=1/7x
Step-by-step explanation:
f(x) = 7x
y=7x x=7y
y=x/7
y=1/7x
f^-1 (x)=1/7x
Answer:
50
Step-by-step explanation:
20% is the same as 0.2 times something.
So you can create the equation 0.2x = 10. The solution of this equation is x=50.
Divide the numbers and you should get your answer after you multiply it by 2 since it’s doubling
$4.5 per pizza. I did 22.50/5
The errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)
<h3>Writing an expression as an equation</h3>
From the question, we are to determine the errors that Emma made
The given statement is
"The quotient of six and a number, x, is the same as negative two times the difference of x and 4.5"
"The quotient of six and a number, x", can be expressed as
6/x
"Two times the difference of x and 4.5", can be expressed as
2(x - 4.5)
Hence, the errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)
