Answer:
y = -1/3
x = 0
Step-by-step explanation:
3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3
4x+3y = -1
substitute for x
4(2/3+2y)-6y = 2
8/3+8y-6y = 2
reduce
2y = 2-8/3
2y = -2/3
divide both sides by 2
y = -1/3
4x+3(-1/3) = -1
4x = 0
x = 0

Answer:
48.
Step-by-step explanation:
To find the missing number write out the equation :
67 + 65 + ? = 180.
67 + 65 = 132
To find out how much more we need you can minus 132 from 180.
180 - 132 = 48.
Plug it in to see if it works.
67 + 65 + 48 does equal 180.
Hope this helps,

Answer:
9%
Step-by-step explanation:
Given that
The invested amount is $1,000
The future value is $2,400
The time period is 12 years
We need to find out the annual rate that compounded continously
So,
As we know that
Amount = Present value × e^(rate × time)
$2,500 = $1,000 × e^(rate × 12)
2.5 = e^(rate × 12)
ln 2.5 = 10r
ln 2.5 ÷ 10 = r
r = 9%
