Answer:

Option A

Step-by-step explanation:

<u>According to the matrix, the system is:</u>

3x + 2y -z = 4
0x + 3y + 7z = 8 ⇒ 3y + 7z = 8
x - 3y + 4z = 7

Correct match is A

Help quick! I'll mark your answer as the brainliest if your answer is correct!

Anna007 [38]

Answer:

They would never intersect because they are parallel lines. You can tell they are parallel lines because they have the same slope and they have a different y-intercept. However, this doesn't mean that there was no solutions, there were, thats how i was able to tell what their slopes and y-intercepts were. So if there is an answer that you can choose from that explains that they won't intersect because they are parallel then that is the correct answer. It may be C, but I would see if there is another option.

Which number is a solution of the inequality?

padilas [110]

we know that

A number is an inequality solution if the number satisfies the inequality

<u>Part 1)</u> $10.6 < b$

rewrite the inequality

$b > 10.6$

The answer Part 1) is the option D $14$

Because $14$ satisfies the inequality

$14 > 10.6$ -----> is true

<u>Part 2)</u> $m > 7/12$

The answer Part 2) is the option A $1$

Because $1$ satisfies the inequality

$1 > 7/12$ -----> is true

<u>Part 3)</u> $8< x(7-x)$

we're going to verify every case

<u>case A)</u> For $x=2$

substitute the value of x in the inequality

$8< 2(7-2)$

$8< 10$ ------> is true

therefore

The number $2$ is a solution

<u>case B)</u> For $x=8$

substitute the value of x in the inequality

$8< 8(7-8)$

$8< -8$ ------> is not true

therefore

The number $8$ is not a solution

<u>case C)</u> For $x=-1$

substitute the value of x in the inequality

$8< -1(7-(-1))$

$8< -8$ ------> is not true

therefore

The number $-1$ is not a solution

<u>case D)</u> For $x=0$

substitute the value of x in the inequality

$8< 0(7-0)$

$8< 0$ ------> is not true

therefore

The number $0$ is not a solution

therefore

The answer Part 3) is the option A $2$

Let f(x) = x + 3 and g(x) = 1/x The graph of (gºf)(x) is shown below what is the range of ( gof) (x) .

charle [14.2K]

Answer:

The range of the function $(g\°f)(x)$ is

B. is all real numbers except $y=0$

Step-by-step explanation:

Given functions:

$f(x)=x+3$

$g(x)=\frac{1}{x}$

To find the range of $(g\°f)(x)$ .

Solution:

In order to find $(g\°f)(x)$ , we will plugin $f(x)$ in function $g(x)$ .

$(g\°f)(x)=g(f(x))$

$(g\°f)(x)=\frac{1}{x+3}$

The graph of the function $(g\°f)(x)$ shows that

1) As $x$ approaches -3 (but never touches the line $x=-3$ ), $y$ tends to positive or negative infinity.

2) As $y$ approaches 0 (but never touches the line $y=0$ ) , $x$ tends to positive or negative infinity.

Thus, the range of the function is all real numbers except $y=0$
