Solve the equations. Show the solution sets on a number line. Check your answers. c 9k+3 =−4

Naddika [18.5K]

Answer:

k = -7/9

Step-by-step explanation:

9k + 3 = -4

9k = -7

k = -7/9

On the number line just make a closed circle at -7/9. No line would be drawn, just the dot

-7/9 would be between 0 and -1, closer to -1

Solve the following equations for x, and give evidence that your solutions are correct (x/2)+(1/3)=(5/6).

azamat

Answer:

x = 1

Step-by-step explanation:

Given equation:

$\frac{x}{2}+\frac{1}{3}=\frac{5}{6}$

Now,

subtracting $\frac{1}{3}$ from both sides

we get

⇒ $\frac{x}{2}+\frac{1}{3}-\frac{1}{3}=\frac{5}{6}-\frac{1}{3}$

⇒ $\frac{x}{2}+0=\frac{5}{6}-\frac{1}{3}$

⇒ $\frac{x}{2}=\frac{5\times3-6}{6\times3}$

⇒ $\frac{x}{2}=\frac{9}{18}$

$\frac{x}{2}=\frac{1}{2}$

Now, multiplying both sides with the number 2, we get

x = 1

Find the inverse of the matrix <img src="https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-4%266%5C%5C8%26-12%5C%5C%

liraira [26]

Answer:

Step-by-step explanation:

If there is a 2x2 matrix as $\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]$

The determinant is given by $\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right]$

<em>Now, if we calculate the value of "ad - bc", we see that:</em>

$(-4)(-12)-(8)(6)=0$

We can't calculate the inverse, the inverse doesn't exist. The answer is D.
