Two Rational Roots: 1 and -1 Walkthrough: See images for explanation!

1,-1 are rational numbers Step-by-step explanation: Given equation: The roots of f(x) are: ⇒ ⇒ ⇒ ⇒ of these roots alone -1,1 is considered rational numbers because all integers are numbers rational. The others are irrational numbers.

B Walkthrough: the roots would be 1 and -1 with respect to the graph

There are two rational roots for f(x) Walkthrough: We are given a function to find the number of rational roots for f(x). Let’s use the remainder theorem that when f(a) = 0, (xa) is a factor of f(x) or x=a is a solution. Replace 1 by xf(1) = 1-2-5+6=0 So x=1 is a solution. Let’s try x=-1 f(-1) = 1-2-5+6 =0 So x =-1 is also a solution and x+1 is a factor We can write f(x) by trial and error as We find that the factor gives two irrational solutions as ±√3. The number of rational roots is therefore 2.

On a coordinate plane, 2 triangles are shown. Triangle A B C has points (negative 4, 4), (negative 4, 1), and (0, 1). Triangle W R

In a coordinate plane, 2 triangles are represented. Triangle ABC has points (4.4 minus), (4.1 minus) and (0.1). Triangle WRS has points (0, minus 1), (1.75, 1.5), (5, minus 1). In the diagram, △ABC ≅ △WRS. What is the scope of △WRS? 10 pieces 11 pieces 12 pieces 13 piecesAnswer 1Walkthrough (C)12 units: Triangle WRS has points W(0, -1), R(1.75, 1.5), and S(5, -1). WRS triangle perimeteranswer 212 units I just passed the good luck test (:answer 3The third option is correct. Step by step explanation: As we have shown that △ABC ≅ △WRS So the perimeter of △ABC is given by AB+BC+CA here, AB = 3 units BC = 4 units AC = x By the Pythagorean theorem, we get that Then the perimeter of △ABC is 3+4+5=12 units So the perimeter of △WRS is also 12 units because they are similar triangles. So the third option is correct.answer 4The answer is 12 Walkthrough:Answer 6The correct answer is 12 units (in edgenuity)Answer 7The correct answer in e2020 is C. 12 unitsAnswer 8c Step by step explanation: go all the way

What is Mathway? Do you also use educational platforms to study? Then this article will guide you about such a Mathway educational app besides this article.Forging technologies and their involvement in our daily lives have become inseparable. Every morning when a person wakes up there is something new in the world of technology, be it in any field like education, sports, networking and more. Technology has helped mankind solve countless problems, but everything has a downside as well. If not used sparingly, technology can also have a detrimental impact on humanity. Technology and issues may seem unrelated or seem clichéd, but they are two sides of the same coin. As much as we involve ourselves in technology, we also have great privileges and obstacles.One of those debatable topics “Technology, boon or curse for students” was covered later in this article. With the impact of the Covid-19 pandemic, education has been geared towards technology, with online education being the only option for students. That said, it has both positive and negative effects on students. If used wisely with jurisdictions, technology is one of the greatest things that has ever happened; but without any control it can be harmful beyond expectation. One Read more
