Answer:

These two equations are equivalent because the order of operations states you work from the right to the left and do the multiplication first. Because we do the multiplication first, we get the same answer as the other equation because the parentheses are also done first, meaning these equations both get the same answer.

What is the slope of a line that passes through the points (9,-6) and (-8,7)?
lianna [129]
<h2>Answer:    slope = - ¹³/₁₇  </h2>

Step-by-step explanation:    

       The question gives us two points, (9,-6) and (-8,7), from which we can find the slope and later the equation of the line.

<u>Finding the Slope  </u>

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)    

                                         =  (7 - (- 6)) ÷ (-8 - 9)  

                                         =   - ¹³/₁₇  

<em><u>Checking my answer:</u></em>

Finding the Equation

<em>We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:</em>

<em>                                  ⇒  </em><em>y - (-6) =  - ¹³/₁₇ (x - 9)</em>

<em>                                          </em>

       

<em>To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.</em>

What is the minimum value of the graph of y=sin x assumes
Alex
Short answer: - 1
The first thing you should do is draw this or get a program to do it. I use desmos. It is included. The graph shows one complete cycle every 2*pi intervals (or 360 degrees.)

You will find no lower value that y = - 1 (nor any value greater than y = 1)
