Answer:

x-y=-2 2/3

Step-by-step explanation:

You can't have the exact value of x and y, so we have to iscolate the variables, which means getting rid of the three. You have to divide to both sides three.

(3x-y)/3=8/3, x-y=8/3 then you can simplify into mixed number, which is 2 2/3.

x-y=2 2/3. Hope it helped!

$300 at 6% for 3 years
Charra [1.4K]
Its I=prt 
so plug it in
I=300(.06)3 i got .06 because you have 6% you have to move the decimal  the left twice 0.06 is what you get
now its basic multiplying
300 times .06 times 3
so it would be 54
I=$54
the balence you get from adding the P to the I so the balence would be 356
Bal=$356

AlladinOne [14]
-6 and -6 because -6 + -6 = -12 , you could also have -8 and -4 because -8 + -4 = -12, or you could also have -10 and -2 because -10 + -2 = -12

Find the measure of <2
jeka57 [31]
<2 = 38 
An iscolese triangle adds to 180 degrees. Thus, the two base angles, which is <2 & <3 should be half of the result from 180 - 104.

180 - 104 (angles in a triangle add to 180 degrees)
 = 76
76 / 2 (iscolese triangle. base angles are equal)
 therefore, 38

Find the derivative of the function at P 0 in the direction of A. ​f(x,y,z) = 3 e^x cos(yz)​, P0 (0, 0, 0), A = - i + 2 j + 3k
Alik [6]

The derivative of f(x,y,z) at a point p_0=(x_0,y_0,z_0) in the direction of a vector \vec a=a_x\,\vec\imath+a_y\,\vec\jmath+a_z\,\vec k is

\nabla f(x_0,y_0,z_0)\cdot\dfrac{\vec a}{\|\vec a\|}

We have

f(x,y,z)=3e^x\cos(yz)\implies\nabla f(x,y,z)=3e^x\cos(yz)\,\vec\imath-3ze^x\sin(yz)\,\vec\jmath-3ye^x\sin(yz)\,\vec k

and

\vec a=-\vec\imath+2\,\vec\jmath+3\,\vec k\implies\|\vec a\|=\sqrt{(-1)^2+2^2+3^2}=\sqrt{14}

Then the derivative at p_0 in the direction of \vec a is

3\,\vec\imath\cdot\dfrac{-\vec\imath+2\,\vec\jmath+3\,\vec k}{\sqrt{14}}=-\dfrac3{\sqrt{14}}
