you are adding two rational numbers with different signs. how can u tell if the sum will be positive,negative,zero

1 answer:

5 0

You can tell if it is going to be negative if there is a number with a greater value. for example -14 minus 7. that would be -7
You can tell if it is positive if one number has a bigger value. for example 12-(-6)=6
And if it is zero it would be something like this
-7+7 sorry that's hard to explain in words hoped this helped you

Answer:

The other factor is 5x-2

Step-by-step explanation:

Using the factorisation method:

Two numbers that multiply to give -10 and add to give +3:

+5 and -2

$5x^{2} +5x-2x-2$

$5x(x+1) -2(x+1)$

$(x+1)(5x-2)$

So the other factor is 5x-2

I'm not sure about the second part of the question but I hope you understood how to deal with the first part.

What linear function represents the line given by the point slope equation y+7= 2/3(x+6)?

aleksandrvk [35]

Answer:

The graph of the line in the attached figure

Step-by-step explanation:

we have

$y+7=\frac{2}{3}(x+6)$

This is the equation of a line into point slope form

The slope is $m=\frac{2}{3}$

The line pass through the point (-6,-7)

To graph the line find the y-intercept

Remember that

The y-intercept of the line is the value of y when the value of x is equal to zero

For x=0

$y+7=\frac{2}{3}(0+6)$

$y+7=\frac{2}{3}(6)$

$y+7=4$

$y=4-7=-3$

The y-intercept is the point (0,-3)

with the point (-6,-7) and (0,-3) plot the line

see the attached figure

Describe the location of point (−5, −5, 5) in three-dimensional coordinate space.

Here's a really cool website that let's you input 3D points!

From the attached picture you can see that the point has moved back 5 units, to the left 5 units, and up 5 units.
