Solve log2x = log53 + 1 by graphing. round to the nearest tenth.

**Answer 1**

3.2 Step-by-step explanation:

**answer 2**

3.2 Walkthrough: This is the correct answer in ed-genuity. To find the answer, first change both sides of the equation in the base change formula. You’ll end up with: When you plug these into a graphing calculator like the one provided by rd-genuity, you get 3.2 as the x-value where the two lines intersect (rounded to the nearest tenth). I hope this helps you!

**answer 3**

x=5 and 1/2 Walkthrough: you need to go to a graph and simplify, it’s much easier, hope this helps!

**answer 4**

A. (-0.8.0), (1.2.0), (2.0) Walkthrough: If you put the equation on a graphing calculator, all points given in this answer option can be found on the graph as the x-intercept.

**Answer 5**

B rearranges in standard form: ax² + bx + c = 0 (a≠ 0) 2x² – 3x – 2 = 0 (x – 2)(2x + 1) = 0 (set each factor to zero and solve for x ) x – 2 = 0 ⇒ x = 2 2x + 1 = 0 ⇒ x = – 0.5

**Answer 6**

Step-by-step explanation: 3.2

**Answer 7**

Walkthrough: Given: To Find: Solve each equation using graphs. Solution: See attached figure. So the values of x are -1, -6 So option B is correct. So the values of x are -1, -6

**Answer 8**

Steps to solve: 2x^2 + 5 = 11x ~Subtract 11x for both sides 2x^2 – 11x + 5 = 0 ~Factor (2x – 1)(x – 5) = 0 ~Solve for each factor 2x – 1 = 0 2x = 1 x = 1/2 x – 5 = 0 x = 5 Good luck!

**Answer 9**

x= 1.8 Walkthrough: We were given the equation; -(6)^(x-1)+5=(2/3)^(2-x) We need to determine the value of via graph. To do this, we can split the right and left sides of the equation to form the following two separate equations; y = -(6)^(x-1)+5 y = (2/3)^(2-x) Next, we plot both equations on the same graph. The solution will be the point where the equations intersect. Find the attachment below for the table; The value of x is 1.785. To the nearest tenth, ax = 1.8

**Answer 10**

y=-0.25x+4.07 y=4.9x-1.64 Step by step explanation: The intersection of the two graphs is the solution of the system of equations using a graphing tool see the attached figure The solution is the point, so the answer is The approximate solution of the system is

What is Mathway? – Mathway and Cheating
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

What is the additive inverse of the polynomial?
What is the additive inverse of the polynomial? –6×3 + 4×2 – 4xAnswer 1Walkthrough: Additive inverse is also known as negation, -1 times the original. We negate every term.answer 26x³ – 4x² + 4x Walkthrough: The additive inverse is the value added to make the expression equal to zero. Given – 6x³ + 4x² – 4x, then the additive inverse is – ( – 6x³ + 4x² – 4x) = 6x³ – 4x² + 4xanswer 3B) 6x³ – 4x² + 4x Explanation: The additive inverse is defined as what we add to a number/expression to get a result of “zero” Examples: -5 is the additive inverse of 5 because -5 + 5 = 0 - x² is the additive inverse of x² as x² – x² = 0 So to get the additive inverse just multiply the number/expression you have by -1 The given expression is: -6x³ + 4x² – 4x We get the inverse additive as follows: -1 (-6x³ + 4x² – 4x) -(-6x³) – (4x²) – (-4x) 6x³ – 4x² + 4x Hope this helpedanswer 4B.
