Answer:

3 ways

Step-by-step explanation:

How many different ways can you place 4 identical marbles in three jars shown below? Note: Every marble needs to be in one of the jars, but not every jar needs to have a marble in it.

We solve using combination

n-1 C r-1 = nCr = n!/r! (n - r)!

n = 4 identical marbles

r = 3 jars

Hence:

4 - 1 C 3 - 1 = 3C2

= 3!/2! (3 - 2)!

= 3 ways

Is 2yx – 3y + 2x = 0 a linear function or not a linear function
g100num [7]

is a linear function because It forms a straight line or represents the equation for the straight line

It has only one degree. Or we can also define it as an equation having the maximum degree 1.  

All these equations form a straight line in XY plane. These lines can be extended to any direction but in a straight form.

The general representation of linear equation is;

y = mx +c

Where x and y are the variables, m is the slope of the line and c is a constant value.

What is the equation of the line that is perpendicular to the given line and has an x-intercept of 6?
zhenek [66]

First we have to find the slope of the givent line and for that we use rise / run method .

The points are (-4,4),(4,-2)

Here rise is

-2-4 =-6

And run is

4-(-4)=8

So slope is

= \frac{-6}{8} = \frac{-3}{4}

And the slopes of perpendicular lines are negative reciprocal of each other .

Therefore the slope of the required perpendicular line is

-(- \frac{4}{3}) = \frac{4}{3}

Now we use slope intercept form, and put x intercept , that is (6,0) and the slope that is 4/3 ,

y=mx+b
\\
0 = \frac{4}{3}*6 +b
\\
0=8+b
\\
b =-8

Therefore required equation is

y= \frac{4}{3}x -8

Correct option is the third option .

Jasmines pet guinea pig gained 8 oz. in one month. what is the integer to describe the weight her pet gained?
katrin [286]
We know that the pet Guinea gained 8 ounces in one month.

The question asks for the weight gained by Guinea in also one month.

Since both the described situation and the question both represent the same weight gained in the same duration, therefore, the required integer will be 8.

Answer: 8 ounces.
