Answer:  Plot the two points (3,-6) and (1, -5). Draw a straight line through those points.

See the graph below.

=============================================

Explanation:

Plot the point (3, -6)

The slope -1/2 means the rise is -1 and the run is 2

  • rise = -1
  • run = 2

If we moved to the right, then we'd drop down 1 and move to the right 2. That would move us from (3,-6) to (5,-7)

We can go in reverse of this. So instead of "move down 1", we move up 1. We're going left instead of right.

-----------

So we start at (3,-6) and move up 1 and to the left 2 to arrive at (1,-5)

Two points on this line are (1, -5) and (3, -6)

Once we have two points, we have enough to graph the line.

See the graph below.

Answer:

To graph this line, move one of the points to positive three on the horizontal (side to side) line and negative six on the vertical (up and down) line. To get a slope of negative 1/2 you move down one point and right two points, and you continue until you reach the edge of the graph. Then you do the opposite on the way up (up one and left two).

Hope this helps!

Samuel has a collection of toy cars. His favorites are the 27 red ones which make up 60%, percent of his collection.
Natasha_Volkova [10]
I'm just gonna assume that the question is what's the total number of cars he has/ the other part of his collection

His whole collection has 45 cars in it. I got that by multiplying 60% by 27 

the other 40% of his collection is made up of 18 cars

Which statement about convergent infinite
balandron [24]

Answer:

B) Convergent infinite geometric series sum to a single value

Step-by-step explanation:

An infinite geometric series of the form \[ \sum_{r=1}^{\infty} ar^{n-1} converges if |r|, so the summation of the series will result in a single value if that is true.

Which equation below gives an incorrect value for the function k(x) = 512 x ?
Rus_ich [418]
The function is  k(x) = 512 · x .

Try 'A':      k(2/3) = (512) · (2/3) =  341.33...   not 64

Try 'B':      k(4/9) = (512) · (4/9) =  257.55...    not 16  

Try 'C':      k(1/3) = (512) · (1/3) =  170.66...    not 8

Try 'D':      k(2/9) = (512) (2/9) =  113.77...    not 8 .

So far, it looks like NONE of the choices is correct.

But wait !  There's more !

What if the actual function is                   k(x)  =  512ˣ
that is,  512 raised to the 'x' power ?
That would be a horse of a different cruller.

Let's try THAT out.

First, here are two facts that we'll need:

         ==>  512 ^ 1/3  =  8
and
         ==>  512 ^ 1/9  =  2 .

OK. NOW ...

Try 'A':  k(2/3) = (512) ^ 2/3  =  8^2 = 64             yes !

Try 'B':  k(4/9)  =  (512) ^ 4/9  =  2^4  =  16        yes !

Try 'C':  k(1/3)  =  (512) ^ 1/3  =  8                      yes !

Try 'D':  k(2/9)  =  (512) ^ 2/9  =  2^2  =  4  not  8 .

So here's what we have learned:

-- The function in the question is actually    k(x) = 512 ^ x

-- Choice-D is the incorrect one.
