You fill a 22 and one half,

1 answer:

7 0

You filled it with a ninth of the way full of water so you just simply divide the capacity of the tube by how much it's filled. In this case:

22.5/9 = 2.5

2<br> 1 point<br> The point, (-3, 7), is on the line y = -3x+7.<br> True<br> O False

sladkih [1.3K]

Step-by-step explanation:

in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
Now let us plug in the value of x=-3
$y = - 3( - 3) + 7 \\ y = - 9 + 7 \\ y = - 2$
now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.

The set of points R(-1, 1), S(2, 4), T(6, 8) are collinear. true or false

Harlamova29_29 [7]

R, S and T are collinear if they are in the same exact line.

It is enough to show that slope of RS is equal (or not) to the slope of ST,

slope of RS $=m_R_S= \frac{4-1}{2-(-1)}= \frac{3}{3}=1$

slope of ST $=m_S_T= \frac{8-4}{6-2}= \frac{4}{4}=1$

the lines through R, S and S, T have the same slope so the three points are collinear.
