Answer:
2(3-x)
Step-by-step explanation:
Division which will give you 0.15!
Times 2nd equation by 2
add to first equation
3x+6y=6
<u>4x-6y=8 +</u>
7x+0y=14
7x=14
divide both sides by 7
x=2
sub back
2x-3y=4
2(2)-3y=4
4-3y=4
minus 4 both sideds
-3y=0
y=0
(x,y)
(2,0)
Answer: Choice C
(4, 18)
=========================================
Explanation:
One point shown on the graph is (2,9)
If we double each x and y coordinate, then
We go from (2,9) to (4,18)
Plotting this point on the graph will be on the same line as the other points.
Or you could note that y/x = 9/2 = 18/4 = 4.5
Answer:
Step-by-step explanation:
An exponential equation has the form
y=ar^x where y=final value, a=initial value, r=rate, and x=time, in this case
y=28000(0.73^x)
So the initial value is 28000 and r=0.73. Since 0.73 is less than one this is an exponential decay representing a 27% loss per year. So B and F are correct.
