Is the system of equations consistent, consistent and coincident, or inconsistent? y=3x+4y=3x+3 Select the correct answer from t
Genrish500 [490]

Answer: Inconsistent

<u>Step-by-step explanation:</u>

y = 3x + 4   → m = 3, b = 4

y = 3x + 3   → m = 3, b = 3

These equations have the same slope but different y-intercepts so they are parallel lines <em>which means they will never intersect.</em>

NOTES

  • one solution: consistent & independent        <em>lines cross</em>
  • infinite solutions: consistent & dependent     <em>same line</em>
  • no solution: inconsistent                                  <em>parallel lines</em>

Micheal solved this inequality as shown: step 1: -6(x + 3) + 10 &lt; -2 step 2: -6x - 18 + 10 &lt; -2 step 3: -6x - 8 &lt; -2 st

<h3>Answer:   addition property of inequality</h3>

================================================

Explanation:

These are the steps to focus on

step 3: -6x - 8 < -2

step 4: -6x < 6

The move from the third step to the fourth step has us adding 8 to both sides. Therefore, we use the addition property of inequality.

That property has four forms

  1. If a > b then a + c > b+c
  2. If a < b then a+c < b+c
  3. If a \ge b then a + c \ge b+c
  4. If a \le b then a+c \le b+c

It's similar to the idea of starting with a = b, then adding c to both sides to get a+c = b+c

We add the same thing to both sides to keep things balanced.

What is the slope of the line
valina [46]

Slope is \frac{rise}{run}

Look at the image below. The rise is labeled in green and the run in pink

In this case the rise is 3 and run is 1

The slope is

\frac{3}{1}

OR

3

Hope this helped!

Jared is constructing a rectangular door for a shed. If the door, shown below, has a width of 42 in. and a diagonal support of 9
Goshia [24]

Answer:

B

Step-by-step explanation:

A rectangular door for a shed has a width of 42 in and a diagonal support of 94 in. The triangle formed by the rectangle's width (first leg), rectangle's length (second leg) and rectangle's diagonal (hypotenuse) is right triangle. By the Pythagorean theorem,

\text{leg}_1^2+\text{leg}_1^2=\text{hypotenuse}^2.

Thus,

42^2+x^2=94^2,\\ \\x^2=94^2-42^2=7072,\\ \\x=\sqrt{7072}=4\sqrt{442}\approx 84\ in
