Answer:

Trey's Number line model is incorrect because it represents the expression 2 1/2 x 3/8. The correct equation is 2 1/2 ➗ 3/8 = 6 2/3. Ms. Nellies has enough vinegar for 6 groups of students

What is the equation of the line that is parallel to the given
frez [133]

Answer:

<h2>y = 1/5x + 4</h2>

Step-by-step explanation:

We need to find the equation of the line parallel to the given line. To do this, we first need to understand what parallel lines are.

Rule 1: Parallel lines are two lines that never cross.

Let's solve!

To solve, we need to know what the slope of the line should be as we are already given the point it should pass through. to do this, we need to use a rule.

Rule 2: The slopes of parallel lines are always the same.

Slope = change y / change x

-4 - -3 (-4 + 3) = -1

-5 - 0 = -5

Slope = 1/5

Now, we can construct our equation

y = mx + b

y = 1/5x + 4

Since none of the answers are this, I assume you meant perpendicular instead. In that case, the answer would be, since the slope would be an opposite inverse of the original line, -5x + 4.

I'm always happy to help :)

Which best describes the equation that the graph represents?
hoa [83]

Answer:

third option

Step-by-step explanation:

time ('x') is the independent variable so that leaves only options 1 and 3 as the answer

is the slope equal to 0.6 or 1.8?

I used the slope formula with the following points:  (1,2) and (5,9)

(9-2) / (5-1) = 7/4 = 1.75, or 1.8

You are wearing a pair of cargo pants with six pockets. You've put $10 in one of the pockets, but you cannot remember which one.
Over [174]
There are 6 pockets all together.  You checked two of them and it wasn't
there.  So you can forget about those 2, and now there are 4 pockets left.

The total number of ways for your next try is 4.
The number that will be successful is 1.

The probability of success on the next one is  <em>1/4  =  25% .</em>

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

Another method of solution, somewhat more complex:

Total number of pockets = 6.
Amount of money missing = $10
First partial sum, i.e. sum of numbers
 in the first part of the problem = 6 + 10  =  16.

Total number of pockets  =  6
Current value of cargo pants on a fashion scale from 1 to 10  =  -2.
Second partial sum =  6 - 2  =  4.

  Probability = (second partial sum) / (first partial sum) = 4/16  =  <em>25% </em>.

Alik [6]
-3 > -7
u have to remember, with negatives, the larger number is smaller in value.

when u plot these numbers on the number line, the number that is farthest to the left is less then...the number that is farthest to the right is greater then. 

-3 is warmer because it is closer to zero then -7.
