Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx
Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5
Then plug K value into equation
Y=6.5X
Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.
Check:
X=50
Y=6.5x50
Y=320
5 hundred is 500
8 tens is 80
So 5 hundred 8 tens is <em><u>580</u></em>
Answer:
y=1/2x+2
Step-by-step explanation:
The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.
To find the gradient is a little more tricky, but we can follow the formula:
, where rise is the vertical value and run is the horizontal value
So we sub in our values:
And simplify:
So now we sub in our new found values into y=mx+c:
y=1/2x+2
The correct question is
<span>A rectangular prism with a volume of 2 cubic units is filled with cubes with side lengths of 1/4 unit. How many cubes does it take to fill the prism?
we know that
[volume of the cube]=b</span>³
b=1/4 unit
[volume of the cube]=(1/4)³------> 1/64 unit³
if 1 cube has a volume of ----------------> (1/64) unit³
x cubes--------------------------------> 2 unit³
x=2/(1/64)-----> x=2*64----> x=128 cubes
the answer is
128 cubes
