Answer:
The correct option is B) zero x = -2.
Step-by-step explanation:
Consider the provided graph y = x + 2
The zeros of a function are the point on which graph intersects the x axis or we can say the value of x when y = 0.
Substitute y = 0 in the provided equation.
0 = x + 2
x = -2
The coordinate is (-2,0). Also the zero of the graph is at x = -2 because it follows the definition of zeros.
Now substitute x = 0 in the provided equation.
y = 0 + 2
y = 2
The coordinate is (0,2).
Now, draw a line passing through the point (-2,0) and (0,2).
The required line is shown in figure 1.
Now consider the provided options only option A and B have the same graph.
But the correct option is B as the zero of the option B is x = -2.
Hence, the correct option is B) zero x = -2.
Answer: The area of the Polygon D is 36 times larger than the area of the Polygon C.
Step-by-step explanation:
<h3> The complete exercise is: "Polygon D is a scaled copy of Polygon C using a scale factor of 6. How many times larger is the area of Polygon D than the area Polygon C"?</h3>In order to solve this problem it is important to analize the information provided in the exercise.
You know that the Polygon D was obtained by multiplying the lengths of the Polygon C by the scale factor of 6.
Then, you can identify that the Length scale factor used is:
Now you have to find the Area scale factor.
Knowing that the Length scale factos is 6, you can say that the Area scale factor is:
Finally, evaluating, you get that this is:
Therefore, knowing the Area scale factor, you can determine that the area of the Polygon D is 36 times larger than the area of the Polygon C.
