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>

The ages of three family children can be expressed as consecutive integers. the square of the age of the youngest child is 4 mor
sukhopar [10]
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1

(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4 
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0

X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11

The youngest child is 10
The middle child is 11
The oldest child is 12

Check
=====
10^2 = 100
(8*12) + 4
96 + 4 = 100 So the results have been checked.

Someone help me with question #1 plzz
Oliga [24]

Answer:

x = 8 units

Step-by-step explanation:

Note that the ratio of the middle-length legs is 12/18, and that of the shortest-length legs is x/12.

Then:

12        x

----- = -----

18       12

... which, through cross- multiplication, becomes 18x = 144.  Then x = 8 units
