To find solutions you have to simplify disjunctives first.

-9x+5\leq17\Longrightarrow x\leq-\frac{4}{3} \\13x+25\leq-1\Longrightarrow x\leq-2 \\

Now write the simplified disjunctives as intervals

x\in\Big(-\infty,-\frac{4}{3}\Big] \\x\in(-\infty,-2]

Since the solution is a disjunction x\leq-\frac{4}{3}\vee x\leq-2 we can rewrite as union of intervals and simplify the union to get solution.

\Big(-\infty,-\frac{4}{3}\Big]\cup(-\infty,-2]\Longrightarrow\boxed{(-\infty,-2]}

The answer is B.

Hope this helps.

Solve for m and show your work. 4n=3m-1
Bad White [126]
4n = 3m - 1

4n = 3m - 1
Subtract 3m from both sides.
-3m + 4n = -1
Subtract 4n from both sides.
-3m = -4n - 1
Divide both sides by -3.
m = 4/3n + 1/3

m = 4/3n + 1/3

xeze [42]

Answer:

D. x-\frac{5}{2}y =  \frac{25}{2}

Step-by-step explanation:

Given

y = \frac{2}{5}x - 5

Required

Determine its equivalent

<em>From the list of given options, the correct answer is</em>

x - \frac{5}{2}y = \frac{25}{2}

This is shown as follows;

y = \frac{2}{5}x - 5

Multiply both sides by \frac{5}{2}

\frac{5}{2} * y = \frac{5}{2} * (\frac{2}{5}x - 5)

Open Bracket

\frac{5}{2} * y = \frac{5}{2} * \frac{2}{5}x - \frac{5}{2} *5

\frac{5}{2}y = x - \frac{25}{2}

Subtract x from both sides

\frac{5}{2}y - x = x -x - \frac{25}{2}

\frac{5}{2}y - x = - \frac{25}{2}

Multiply both sides by -1

-1 * \frac{5}{2}y - x * -1 = - \frac{25}{2} * -1

-\frac{5}{2}y + x =  \frac{25}{2}

Reorder

x-\frac{5}{2}y =  \frac{25}{2}

<em>Hence, the correct option is D</em>

x-\frac{5}{2}y =  \frac{25}{2}
