Answer:

y=-2/3x+490

Step-by-step explanation:

As we know the formula for slope intercept form would be y=mx+b

therefore we arrange our numbers in the following manner:

First subtract 2x from 2x so it'll be like 2x-2x and they cancel each other out so keep that in mind, now what you do on one side you have to do it on the other side as well therefore you'll putt -2x on the other side now we are left our equation as 3y=1,470-2x

Second, as we want our form to be slope intercept form I believe that y should be by it self and to do that you need to divide 3 from y, now remember that what you do on one side you have to do it on the other. So you'll divide 3 from all the numbers on the other side. Now on the other side we have 1,470-2x so we will divide 1,470/3=490 and -2x/3 now we are left with y= 490-2/3x ( i left -2/3x as that because dividing makes it a decimal and a decimal and the fraction has the same value so I just left it as a fraction)

Thirdly, sense we want our equation as a slope intercept form we will need to rearange our equation which we need to keep in mind the form which is y=mx+b so that makes it to our answer y=-2/3x+490

Hope this helps :)

Factor completely. 150m^2nz+20mn^2c-120m^2nc-25mn^2z

Anika [276]

Answer:

The factor form is:

$5mn\left(6m-n\right)\left(5z-4c\right)$

Step-by-step explanation:

Here we have to find the factor of the expression:

$150m^2nz+20mn^2c-120m^2nc-25mn^2z$

So we need to take out the common terms, as we do for finding the greatest common factors.

Now the expression that is given can be re-written as:

$150m^2nz+20mn^2c-120m^2nc-25mn^2z\\=150mmnz+20mnnc-120mmnc-25mnnz\\=30\cdot \:5nmmz+4\cdot \:5nmnc-24\cdot \:5nmmc-5\cdot \:5nmnz$

Next, we will find the common terms, as follows;

$30\cdot \:5nmmz+4\cdot \:5nmnc-24\cdot \:5nmmc-5\cdot \:5nmnz\\=5nm\left(30mz+4nc-24mc-5nz\right)\\$

Now we will factorise the expression:

$\left(30mz+4nc-24mc-5nz\right)\\$

as follows;

$\left(30mz+4nc-24mc-5nz\right)\\=6m\left(5z-4c\right)+n\left(4c-5z\right)\\=\left(-4c+5z\right)\left(6m-n\right)\\$

So the final factor form is:

$150m^2nz+20mn^2c-120m^2nc-25mn^2z=5mn\left(6m-n\right)\left(5z-4c\right)$

Help how do I do this

Anna71 [15]

This is a form of the Pythagorean Theorem. We just need to know how far we went in the x direction and how far in the y direction then use
a^2 + b^2 = c^2 to find the value.

distance in the x direction (-4 to -4) that's easy it didn't move. so that is zero and thus would make the distance all in the y direction.

To move from 8 to -8 we take (8 - (-8)) = 8 + 8 = 16 which is your answer
