Answer:
x = -1, y = -5
Step-by-step explanation:
x + y = -6
2x - y = 3
Add the two equations together to eliminate y
x + y = -6
2x - y = 3
------------------
3x = -3
Divide by 3
3x/3 = -3/3
x = -1
Now find y
x+y = -6
-1+y = -6
Add 1 to each side
-1+1 +y = -6+1
y = -5
Answer:
F = 2
Step-by-step explanation: If you want to know which one is a solution, you have to substitute the numbers in for F.
F = 7:
3 > f
3 > 7
This is false because 3 is NOT greater than 7, it is less than 7.
F = 9:
3 > f
3 > 9
This is false because 3 is NOT greater than 9, it is less than 9.
F = 2:
3 > f
3 > 2
This is TRUE because 3 IS greater than 2.
Hope this help you!!! :)
So 20600=100%
in 2009=1.2% change from 100%
not specific whether percent change is up or down so solve fo r1.2%
d
find 1.2% of 100
percent means parts out of 1001.2%=1.2/100=0.12/10=0.012/1=0.012
'of' means multiply
20600 times 0.012=276.2
the change is 276.2
20600-276.2=20352.8
20600+276.2=20847.2
you must round down since you can't sell 0.2 or 0.8 of a car
the sold either 20,352 or 20,847 cars in 2009
Reference angle of -3 radians is α= - 171° 53 min 15 sec .
We know the formula for calculating circular arc
Let l=circular arc which ic according to central angle of the circle α
l=((2R π)/360)α Let l=1 radian and R=1 (unit circle with radius R=1)
1= ((2π)/360)α => α= 360/(2π)= 180/π= 57° 17 min 45sec
Angle of the 1 radian is equal to angle 57° 17min 45sec
According to this
angle of the -3 radians = -3 ( 57° 17min 45sec) = - 171° 53min 15sec
when you count in the clockwise direction.
Good luck!!!
The inverse of y = log (8x) would be:
y=Log8^x=xlog8=xlog2^3=3xlog2
y=3log2 * x
<span>
the inverse function is </span>
<span>
x=3log2*y </span>
<span>
y=x/3log2
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
