What is the strongest relationship you can infer between two variables from this statement?

The <em>correct answer</em> is:

Causation.

Explanation:

As the battery charge of a phone decreases, the amount of time you can perform any action with the phone decreases, including the number of minutes you can talk. This is because after a certain amount of time, there will be no more battery charge, which means you will not be able to use the phone at all.

Trinity solved the equation 2(x-3)+7-3x=11.

lukranit [14]

Answer:

$x=-10$

Step-by-step explanation:

$2(x-3)+7-3x=11$

$2\left(x-3\right)+7-3x-7=11-7$

$2\left(x-3\right)-3x=4$

$-x-6=4$

$-x-6+6=4+6$

$-x=10$

$\cfrac{-x}{-1}=\cfrac{10}{-1}$

$x=-10$

Choose the equation that represents a line that passes through points -3,2 and 2,1

STatiana [176]

bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-2}{2-(-3)}\implies \cfrac{1-2}{2+3}\implies -\cfrac{1}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-2=-\cfrac{1}{5}[x-(-3)]\implies y-2=-\cfrac{1}{5}(x+3)$

$\bf y-2=-\cfrac{1}{5}x-\cfrac{3}{5}\implies y=-\cfrac{1}{5}x-\cfrac{3}{5}+2\implies y=-\cfrac{1}{5}x+\cfrac{7}{5} \\\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{5}}{5(y)=5\left( -\cfrac{1}{5}x+\cfrac{7}{5} \right)}\implies 5y=-x+7\implies \blacktriangleright x+5y=7 \blacktriangleleft$
