For what value of a does (1/9)a+1 =81a+1 272-a?
AlexFokin [52]

Answer:

-4

Step-by-step explanation:

\left( \dfrac{1}{9}\right)^{a+1}= 81^{a+1}\cdot 27^{2-a}\\\\\\(3^{-2})^{a+1}=(3^4)^{a+1}\cdot (3^3)^{2-a} \\\\\\3^{-2a-2}=3^{4a+4}\cdot 3^{6-3a} \\\\\\3^{-2a-2}=3^{a+10} \\\\\\-2a-2=a+10 \\\\\\-3a=12 \\\\\\a=-4

Hope this helps!

*HELP ME PLEASE* Consider the equation: 3x + 1 – 9 = 3(x + 2) + n.
Lubov Fominskaja [6]

Answer:

n  = -14

Step-by-step explanation:

Let us try to solve this equation for n;

     3x + 1 - 9  = 3(x + 2)  + n

     3x  - 8  = 3x + 6 + n

      3x - 3x -8 - 6  = n

              -14  = n

The value of n  = -14

This value is the value of the equation that will have no solution.

 To know if we are correct, let us input this value into the expression

        3x + 1 - 9  = 3(x + 2)  + n

        3x - 8  = 3x + 6 -14

 Collect like terms;

        3x - 3x  = 8 + 6 - 14

               0 = 0

Which graph shows the solution to the system of linear inequalities? y ≥ 2x + 1 y ≤ 2x – 2
Artyom0805 [142]

Answer:

Step-by-step explanation:

Given the two inequalities:

y \ge 2x + 1\\ y \le 2x - 2

To graph them, first of all, let us write their corresponding equations:

y = 2x + 1 \\y = 2x - 2

We now find at least 2 points each which satisfy the equations to plot the graph.

Equation y = 2x + 1:

Putting x = 0, y = 1

Putting y = 0, x = -\frac{1}2.

Two points are (0, 1) and (-\frac{1}2, 0).

Equation y = 2x -2:

Putting x = 0, y = -2

Putting y = 0, x = 1.

Two points are (0, -2) and (1, 0).

Now, let us plot them.

Let us take a point (1, 4) and check whether it satisfies the first inequality.

4 \ge 2 \times 1 +1\\\Rightarrow 4 \ge 3

Which is true.

So, The shaded region will be <em>towards point (1,4).</em>

<em></em>

Let us take a point (1, 4) and check whether it satisfies the second inequality.

4 \le 2 \times 1 -2\\\Rightarrow 4 \le 0\ [\bold{False}]

So, The shaded region will be <em>opposite to point (1,4).</em>

Please refer to the attached graph for the answer.

<em>No solution exists for them because there is no common shaded region</em>.
