Answer:

I need more info but if your wondering how much each notebook cost the answer is

Step-by-step explanation:

So first we have to divide 28/8 beacuse thats how many over how much.
When we do it it becomes 3.5. Now this is our number but we must add a zero to the end, so now it $3.50. $3.50 for each notebook!

Hope this helps you, :3

Answer:

(a) $-\sqrt{10}y$

(b) $-\sqrt{3}y$

Step-by-step explanation:

(a) $\sqrt{10y^{2}}$ can also be written as $\sqrt{10}$ x $\sqrt{y^{2}}$

the $\sqrt{y^{2}}$ = ± y

Therefore :

$\sqrt{10y^{2}}$ = ± $\sqrt{10}y$

since it was given that y < 0 , then the factor will be $-\sqrt{10}y$

(b) $\sqrt{3y^{2}}$ can also be written as : $\sqrt{3}$ x $\sqrt{y^{2}}$

Therefore , one of the factor is $-\sqrt{3}y$

If point A(-5, 2) is rotated 90 degrees clockwise about the origin, what will be the coordinates of the point in its new positio

Anettt [7]

Answer:

(2,5)

Step-by-step explanation:

Keep in mind that clockwise is towards the right in this problem. We are moving the point from quadrant 2 to quadrant 1.

Draw a picture for yourself to help this make sense. Put the point, then just turn your whole paper 90 degrees to the right. This is your new point!
