6 0

Answer:

  see below

Step-by-step explanation:

The problem is set up properly.

The factor of x was not properly multiplied by the first two terms of the trinomial. Terms were not combined correctly.

The proper multiplication and combining of terms is shown in the attachment. The green diagonal lines show the like terms that need to be combined to form the result.

Adrianna is attempting to write an inequality from a graph. She knows that the dash boundary line passes through the points (27,
SVEN [57.7K]

we know the line passes through those points, so let's find the EQUATion of it firstly.


\bf (\stackrel{x_1}{27}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{-45}~,~\stackrel{y_2}{-54}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-54-10}{-45-27}\implies \cfrac{-64}{-72}\implies \cfrac{8}{9} \\\\\\ \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-10=\cfrac{8}{9}(x-27) \\\\\\ y-10=\cfrac{8}{9}x-24\implies y=\cfrac{8}{9}x-14


so, that's its EQUATion, now, we know the (0,0) is a solution of this inequality, namely the (0,0) point lies in the "true region" or will be the "shaded region" of the inequality, let's plug those values,


\bf y=\cfrac{8}{9}x-14\implies \stackrel{\textit{using x = 0, y = 0}}{0=\cfrac{8}{9}(0)-14}\implies 0=-14


well, clearly  0 is not equals to -14....  we know 0 is greater, recall for the negative values, the farther from zero the smaller.

we also know that the line is dashed, meaning the borderline values are not included, so is either a > or <, thus since 0 > -14, then

\bf y>\cfrac{8}{9}x-14

X is an odd number and the sum of the next two consecutive even numbers is less than 90.
Mila [183]

Answer:

41

Step-by-step explanation:

Let the odd number be x

Therefore,

(x + 1) + (x + 3) < 90 \\ 2x + 4 < 90 \\ 2x < 86 \\ x < 43

Therefore, Largest possible odd number of x is 41
