Answer: The second one
Step-by-step explanation:
That's the only set where there is only one output for every input.
<h3>Answer:</h3>
- Calvin: incorrect, sign error
- Greg: incorrect, has no relationship to the given expression
- Ruben: incorrect, sign error
- Equivalent expresssion: 7 92(4x -11)
<h3>Explanation:</h3>
The two terms on the right, -8x and +22, have even coefficients, so a factor of 2 can be factored out. If we do that, then these two terms become ...
... 2(-8x/2 +22/2) = 2(-4x +11)
We could, instead, factor out -2 so the x-coefficient inside parentheses is positive:
... -2(-8x/-2 +22/-2) = -2(4x -11)
Note that the signs of the two terms inside parentheses are different no matter which way we do it.
<u>Equivalent expressions</u>
Calvin could have written: 7 -2(4x -11)
Ruben could have written: 7 +2(-4x +11)
Greg could have written: 8(2 -x) -1. He would have rearranged the expression to 16 -8x -1 before doing so.
Answer:
The Fringe of the rug is 754 cm.
Step-by-step explanation:
Given:
radius = 120 cm
We need to find the fringe of the outside rug.
Solution:
Since the rug is in the circular form.
We can say that fringe of the outside edge of the rug can be equal to circumference of the circle.
Then we will find the Circumference of the circle.
Circumference of the circle is given 2 times 'π' times radius 'r'.
framing in equation form we get;
Circumference of the circle = 
Circumference of the circle = 
Hence the Fringe of the rug is 754 cm.
Answer:
3
Step-by-step explanation:
1. Write out the equation
2. Subtract 6 from each side
3. Divide by 4 on each side
ANSWER

EXPLANATION
The given equation is

Divide both sides by


Cancel out common factors on the left hand side,

For this solution to be a whole number, then

should be a factor of

.
The reason is that, factors of 6 will divide exactly in to 6 without a remainder, making the answer a whole number.
The whole numbers that are factors of 6 are,

Note that, the set of whole numbers are,
