Write the linear equation that gives the rule for this table.

Zinaida [17]

Answer:

f(x) = -7x + 1

Step-by-step explanation:

Slope intercept form is

y = mx + b

m is slope

b is y-intercept

--------------------------

y decreases by 7 for each increase of 1 in x

slope = -7

to find "b" plug in one of the points and m = -7

using point (3, -20)

y = mx + b

-20 = -7(3) + b

-20 = -21 + b

b = 1

The equation is

f(x) = -7x + 1

24 metal spheres are melted, and the liquid is poured into a rectangular mold. The radius of each sphere is 4 cm. The length of

astra-53 [7]

So first, let's calculate the total volume of all metal spheres.

Total volume = number of spheres * 4/3* πr³
Total volume = 24*4/3*3.14*4³ = 6430.72 cm³

Now, let's equate this to the volume of the rectangular prism. The volume of a rectangular prism is:

V = LWH, where L is the length, W is the width and H is the height

Thus,

6430.72 = (6 cm)(2 cm)(H)
Solving for H,
<em>H = 535.9 cm</em>

What is the distance between the points (-4, 6) and (1, -6)?

Oksanka [162]

Answer:

The distance between these 2 points is 13.

Step-by-step explanation:

Picture the 2 points on a graph as a right triangle, where the hypotenuse of that right triangle is the distance between the points. It is very easy to find the length of the legs of that triangle, and you can use those legs to calculate the length of the hypotenuse.

First, find the vertical distance, or the distance between the y-coordinates. Either just look at a graph and count, or subtract them.
