Nataliya [291]
If you would like to solve the equation x - 6 = - 14, you can calculate this using the following steps:

x - 6 = - 14
x = - 14 + 6
x = - 8

The correct result would be d. - 8.

Nancy left a bin outside in her garden to collect rainwater. She notices that 1/2 gallon of water fills 2/3 of the bun. Write an
Eva8 [605]

Answer:

  • 3/4 gallons

Step-by-step explanation:

Let the capacity of the bin is x gallons.

1/2 gallon is 2/3 of x

<u>Convert this into equation and solve for x:</u>

  • 1/2 = 2/3x
  • x = 1/2 : 2/3
  • x = 1/2 * 3/2
  • x = 3/4

3/4 gallons of water will fill the bin

Please help! I am completely lost on these things
Flauer [41]
Its pythagoras I think ^^; so 9^2 + 4.5^2 = 101.25 then square root it to get 10.0623059   just in future do a^2 + b^2 = c^2 (adjacent squared plus opposite squared gives you the longest side which is the hypotenuse squared) I hope that helps! ^^;

find an equation of the line through the given points. give the final answer in slope-intercept form (-2,2) (4,-1)​
Pachacha [2.7K]

to get the equation of any straight line, we simply need two points off of it, let's use the points in the picture below.

(\stackrel{x_1}{-2}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-1}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{(-2)}}}\implies \cfrac{-3}{4+2}\implies \cfrac{-3}{6}\implies -\cfrac{1}{2}

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{-\cfrac{1}{2}}(x-\stackrel{x_1}{(-2)}) \\\\\\ y-2 = -\cfrac{1}{2}(x+2)\implies y-2=-\cfrac{1}{2}x-1\implies y=-\cfrac{1}{2}x+1
