Answer: 5/6 pages per minute

Explanation:

1.) set up problem

7 1/2 ÷ 9

2.) make 7 1/2 an improper fraction by multiplying 7 by the denominator of 1/2 and adding it to the numerator

15/2 ÷ 9

3.) flip the division sign to a multiplication sign and set a 1 over 9

15/2 • 1/9

4.) multiply

15/28

5.) simplify

5/6

Write the standard equation for the circle 30. Center (2,7), r=4. 31. Center (-6,-8), that passes treough (0,0)

Salsk061 [2.6K]

The standard equation of the circle is:

(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...

so

30.

(x-2)^2+(y-7)^2=16

31.

We need to find the radius...(I'll just use the Pythagorean Theorem)

r^2=6^2+8^2

r^2=36+64

r^2=100 (so the radius is 10) and its center is (-6,-8) so

(x+6)^2+(y+8)^2=100

Sum : $(5 x+1)$

Term : 1, $5x$ and $3y$

Product : $9(5x+1),5x$ and $3y$

Factor : 5 and x, 3 and y, 9 and 5x+1

Quotient : $\frac{9(5x+1)}{3y}$

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

Explanation:

The expression is $\frac{9(5x+1)}{3y}$

Sum: Sum is the result of addition of terms.

Thus, from the expression,

Sum = $(5 x+1)$

Term : A term is a single number or a variable or a number multiplied with a variable.

Thus, from the expression,

Term = 1, $5x$ and $3y$

Product : Product is the result of multiplication of numbers.

Thus, from the expression,

Product = $9(5x+1),5x$ and $3y$

Factor : The numbers that are multiplied is called a factor.

Thus, from the expression,

Factor = 5 and x, 3 and y, 9 and 5x+1

Quotient : Quotient is the result of dividing two numbers or variables.

Thus, the given whole expression is a quotient.

Hence, Quotient = $\frac{9(5x+1)}{3y}$

Coefficient : Coefficient of a variable is a number multiplied with a variable.

Thus, from the expression,

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

What is slope and how do you find it??

lions [1.4K]

the formula for slope is

$\frac{(y2-y1)}{(x2-x1)}$

so just replace y and x for the proper values

A set X consists of all real numbers greater than or equal to 1. Use set-builder notation to define X.

vitfil [10]

Theory:

The standard form of set-builder notation is 

{ x | “x satisfies a condition” }

This set-builder notation can be read as “the set of all x such that x (satisfies the condition)”.

For example, { x | x > 0 } is equivalent to “the set of all x such that x is greater than 0”.

Solution:

In the problem, there are 2 conditions that must be satisfied:

1st: x must be a real number

In the notation, this is written as “x ε R”. Where ε means that x is “a member of” and R means “Real number”

2nd: x is greater than or equal to 1

This is written as “x ≥ 1”

Answer:

Combining the 2 conditions into the set-builder notation:

X = { x | x ε R and x ≥ 1 }
