Given:
The graph of an inequality.
To find:
The inequality for the given graph.
Solution:
From the given graph it is clear that the related line is a vertical line parallel to the y-axis at a distance of 7 units from the left of y-axis. It intersect the x-axis at x=-7.
So, the related equation for boundary line is
The shaded region is on the left side of the boundary line. it means, the value of x which are less than -7 are included in the solution set.
The boundary line is a solid line. It means -7 is also included in the solution set.
The value of x is less than or equal to -7. So, the inequality for shaded region is
Therefore, the correct option is B.
The true statement is (b) she did not represent the two original factors correctly on the headers
<h3>How to determine the true statement?</h3>
The product expression is given as:
(-2x - 1)(2x - 1)
Expand the expression
(-x - x - 1)(x + x - 1)
This means that the header of the algebra tiles would be:
-x, -x, 1 and x, x and -1
From the figure, we can see that this is incorrectly represented
Hence, the true statement is (b)

Well, you are trying to simplify the numbers and the equation. You are trying to get the smallest possible number or solution. A difference between the two is that polynomials have factors and variables. Numbers are just numbers. With a polynomial, you have to combine like terms and try to reduce the length of the equation. You may not always fully solve a polynomial. With numbers, you probably will get an exact numeral answer.
Answer:
In mathematics, there are some properties of numbers that are handy to know. For example, the identity property of multiplication says that any number times one is equal to the original number. So, according to that property 5 x 1 = 5.
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. Create an equation
<em><u>Concept</u></em> :
If x = 5, then subtracting 5 from both sides gives you x - 5 = 0. Do this to both variables
If x - 5 = 0 and y - 12 = 0, those two statements equal the same thing. So
2. Add 5 to both sides to isolate variable X
3. (Optional) Plug given values into new equation to check answers
5 = 5 is a true statement
