Step-by-step explanation:
3/2 is 1½ so that means 1½ divided by 2 is <em><u>3/4</u></em>
Answer: The correct option is second.
Explanation:
The given function is,

If we graph a function is f(x), then its coordinates is defined as (x,f(x)).
When the graph of f(x) is reflect across the x-axis, then the the x-coordinate remains the same and the sign of y-coordinate is changed. It means after reflecting across the x-axis,

The given given equation can be written as,

To find the equation of the graph after reflection across the x-axis multiply both sides by -1.

Because f(x)=y and g(x)=-y.

Therefore the second option is correct and the graph of both function is given below.
Answer:
3
Step-by-step explanation:
area of square=l*b so
81=3x multiply 3x
81=9x^2
81/9=x^2
9=x^2
=x
3=x
Let

, so that

is the digits in the tens place and

is the digit in the ones place. (Clearly

.)

There are five possible two digits integers that satisfy this relation:





But the first, third, and fifth candidates are even, so they are not prime. The remaining are prime, however, so

or

.
Answer:
the short piece is 28 and the long piece is 56
Step-by-step explanation:
you can label the short piece x and the long piece as 2x
84= short (x)+ long (2x)
84=x+2x
84=3x
x=28
