Explain how to show the multiplication of 3 and -4 on a number line

Mathematics

The multiplication of 3 and -4 on a number line is shown

<h3><u>Solution:</u></h3>

The number line representation is shown below

On number line the points are at equal distances

The multiplication of 3 with -4 can be understood in the following way:-

a × b , means a jumps b times

Eg :-  3 × -4 means 3 jumps -4 times

Which basically mean we are going to move 3 number  per step , and we are going to do this 4 times and –ve sign indicates we will move in negative direction

Therefore,

So, when we move from 0 , when we take first step we reach -3 , in next step we reach -6 , in next we reach -9 and in the last step we reach -12

Which is the product 3 and -4 .i.e. 3 \times 4 =-12

Answer:

H

Step-by-step explanation:

If it was the first two, it would be to small of an angle.

If it were the last two it would be a straight line.

35 degrees is the only possible one.

What is the equation of the line shown in this graph? <br><br> The points are (-2, 2) and (-2, -3)
KengaRu [80]

\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{-3}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-2}{-2-(-2)}\implies \cfrac{-3-2}{-2+2}\implies \stackrel{und efined}{\cfrac{-5}{0}}


so our slope is undefined, that means a vertical line, check the picture below

What is the scientific notation of 68000
Dmitry [639]
OOHHH!! I like sci not! Okay, so you take the decimal ( which in this case is at the end: 68000. ) and move it over as many times as needed until it gets in between the, in this case, 6 and 8. ( 6.8000 ). You need to show exactly how many times it was actually moved so you multiply that number time 10^ whatever place. In this question, it'll be to the 4th place because you move the decimal over 4 times. The answer will be 6.80 x 10^4 OR -written in short hand- 6.8x10E4

What is the equation of the line passing through the points (4, -7.5) and (6, -3.5) in slope-intercept form?
Ratling [72]

Answer:

Your answer will be

y=2x-15.5

Step-by-step explanation:

Hi, there you must know the slope-intercept form which is

y=mx+b

m=slope

b=y-intercept

You can also use

the slope formula which is

\frac{y_2-y_1}{x_2-x_1}

in this case

it will look like this

\frac{-7.5-(-3.5)}{6-4}=\frac{-4}{2}=-2

So the slope is -2

Now we will find the y-intercept

-7.5=2(4)+b

-7.5=8+b   Subtract 8 both sides

-15.5=b

Your y-intercept is -15.5

Hope this helps
