Answer:
5*3
Step-by-step explanation:
because it is a different operation
Answer:
See the explanations below
Step-by-step explanation:
Given the function y = x²+12x
We are to find the inverse and identify the error in the calculation:
Step 1: Replace y with x
x = y²+12y
First Error: There is an error here y, the variable attached to x should be y and not x that is y = y²+12y and not y = y²+12x. The x should be totally replaced with
The second error is where he wrote y = √-11x
The square root of a value must return both negative and positive value not only the positive value. Hence the correct expression should have been y = ±√-11x (Note that the sign ± was introduced)
Third error: Since the value inside the square rot is a negative value hence the value of x must be negative i.e x must be less than zero not greater then. The correct inequality expression should have been <u>x <0</u> and not
x< 0
Answer: 1/3
Step-by-step explanation:
Each friend gets 1/3
1/3 / 9 = 3
Answer:
A, C and F
Step-by-step explanation:
According to exponent laws:
Therefore F needs to be checked
this can further be simplified into:
we square the denominator and numerator
therefore C should be checked
if we expand it will also look like :
so A should be checked
This is a proportion problem
Info needed: there is 36 inches in a yard
1/36= x/18
Cross multiply and divide
18 x 1= 18
18 divided by 36= .5 or 1/2
Answer is 1/2
You could have also known that 18 inches was half of 36 inches. Which 36 inches equals one yard
