Yes it does, all you have to do is plug in the values and you will be able to figure it out

You should solve for y= mx+b and then plug in the coordinates for x and y.

if u solve for y= mx+b you will get 3x+7=y

then you plug in (-3,-2) for x and y
and (1,10)

you will get that both coordinates do in fact pass through 3x-y=-7

The perimeter of the scalene triangle is 54.6 cm.
valina [46]
Are you sure it’s a scalene triangle because if you only know one side and all the other sides are different lengths then it’s impossible to computer unless we know angle measures. It would have to be isoceles or we would need angle measures

Evaluate the expression for x=-6 4more than the product of-4 and the number ​
son4ous [18]

Answer:

28

Step-by-step explanation:

The product of -4 and the unknown number n is -4n.

4 more than the product of -4 and the unknown number n is -4n + 4.

Letting n = -6 results in the value  -4(-6) + 4, or 24 + 4, or 28.

What is the volume of this triangular prism?
Liula [17]

Answer:

5676.16 cm^3

Step-by-step explanation:

The volume of any prism is given by the formula ...

V = Bh

where B is the area of one of the parallel bases and h is the perpendicular distance between them. Here, the base is a triangle, so its area will be ...

B = 1/2·bh

where the b and h in this formula are the base and height of the triangle, 28 cm and 22.4 cm.

Then the volume is ...

V = (1/2·(28 cm)(22.4 cm))·(18.1 cm) = 5676.16 cm^3

_____

You will note that this is half the product of the three dimensions, so is half the volume of a cuboid with those dimensions. Perhaps you can see that if you took another such prism and placed the faces having the largest area against each other, you would have a cuboid of the dimensions shown.
