<h3>Beatrice concluded that all of these points are on the same line is false statement. </h3>

<em><u>Solution:</u></em>

Given that,

Beatrice calculated the slope between two pairs of points

She found that the slope between (-3, -2) and (1, 0) is \frac{1}{2}

She also found that the slope between (-2, -1) and (4, 2) is \frac{1}{2}

Beatrice concluded that all of these points are on the same line

The points are on the lines with the same slopes.

We know that, two parallel lines will also have the same slopes

Therefore,

Beatrice need to find the y-intercept of the equation of the lines

If the y-intercept of the equation of lines is same in both cases,

Then this means that all 4 points are on the same line

Or else, they are two different lines which are parallel

<em><u>Find the y intercept of (-3, -2) and (1, 0)</u></em>

The slope intercept form is given as:

y = mx + c ------ eqn 1

where, "m" is the slope and "c" is the y intercept

Substitute m = 1/2 and (x, y) = (1, 0) in eqn 1

0 = \frac{1}{2} \times 1 + c\\\\c = \frac{-1}{2}

Thus y intercept is -1/2

<em><u>Find the y intercept of line of (-2, -1) and (4, 2)</u></em>

Substitute m = 1/2 and (x, y) = (4, 2) in eqn 1

2 = \frac{1}{2} \times 4 + c\\\\2 = 2 + c\\\\c = 0

Thus y intercept is 0

The two lines, have same slope but ,different y intercept which means lines are parallel

So, Beatrice concluded that all of these points are on the same line is false statement.

vodka [1.7K]

Answer:

b = -152

Step-by-step explanation:

  1. 7 + 12 = 19
  2. Plug 19 in: \frac{b}{19} = -8  
  3. Multiply each side by 19 to cancel out the 19 under b. It should now look like this: b = -152

I hope this helps!

Sarah is making strings of beads in the first string she uses 3 beads and she triples the number of beads in each of the next st
xenn [34]

Answer:

She uses 243 beads for the 5th string.

Step-by-step explanation:

In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:

The second uses 9, 3 * 3 = 9

The third uses 27, 9 * 3 = 27

The fourth uses 81, 27 * 3 = 81

And the 5th uses 243, 81 * 3 = 243.

Choose all options that are expressions 6+5w 3-16v 4v+1 2v=0 18=v 7-v
Nataly [62]

Answer:

The expressions here are;

6 + 5w

3-16v

4v+ 1

7-v

Step-by-step explanation:

Here, out of the given set, we want to choose all options that are expression.

To do this, we should understand that expressions do not have the equality sign like equations

So expressions are those in the set in which we do not have an equality sign

The right answer is thus;

6 + 5w

3-16v

4v + 1

7-v
