What is the contra positive of the statement if 9x=27, then x=3

Karo-lina-s [1.5K]

Answer:

If 9x is not =27, then x is not =3

Step-by-step explanation:

Going out on a limb here, please ignore if I'm missing it:

If 9x is not =27, then x is not =3

(I can't type the equal sign with a slash through it.)

In this problem we use the change of variables x=5s+tx=5s+t, y=s−ty=s−t to compute the integral ∫r(x+y)da∫r(x+y)da, where rr is

Mazyrski [523]

$x=5s+t$

$y=s-t$

The Jacobian matrix for this transformation is

$\mathbf J=\dfrac{\partial(x,y)}{\partial(s,t)}=\begin{bmatrix}\dfrac{\partial x}{\partial s}&\dfrac{\partial x}{\partial t}\\\\\dfrac{\partial y}{\partial s}&\dfrac{\partial y}{\partial t}\end{bmatrix}=\begin{bmatrix}5&1\\1&-1\end{bmatrix}\implies\det\mathbf J=-6$

The vertices in the $x,y$ plane correspond to the following points in the $s,t$ plane:

$(x,y)=(0,0)\implies\begin{cases}5s+t=0\\s-t=0\end{cases}\implies(s,t)=(0,0)$

$(x,y)=(5,1)\implies\begin{cases}5s+t=5\\s-t=1\end{cases}\implies(s,t)=(1,0)$

$(x,y)=(6,0)\implies\begin{cases}5s+t=6\\s-t=0\end{cases}\implies(s,t)=(1,1)$

$(x,y)=(1,-1)\implies\begin{cases}5s+t=1\\s-t=-1\end{cases}\implies(s,t)=(0,1)$

That is, the parallelogram $\mathcal R$ is mapped to a square $\mathcal R^*$ in the $s,t$ plane, so

$\displaystyle\iint_{\mathcal R}x+y\,\mathrm dA=\iint_{\mathcal R^*}((5s+t)+(s-t))|\det\mathbf J|\,\mathrm ds,\,\mathrm dt$

$=\displaystyle6\int_{t=0}^{t=1}\int_{s=0}^{s=1}6s\,\mathrm ds\,\mathrm dt=18$

Somebody help and explain!!!

Answer: The midpoint of segment PQ is the number 2.5

note: 2.5 as a fraction is 5/2; as a mixed number 2.5 converts to 2&1/2

============================================================

Explanation:

Apply the midpoint formula to get the midpoint of -8 and 6

We simply add up the values and divide by 2 and we get (-8+6)/2 = -2/2 = -1

So point Q is at -1 on the number line, which is exactly halfway from R to P

Focus on just points P and Q now. Apply the midpoint formula again

Q = -1

P = 6

(Q+P)/2 = (-1+6)/2 = 5/2 = 2.5

So the midpoint of segment PQ is 2.5

The decimal 2.5 can be written as the mixed number 2&1/2, showing that this new point is exactly halfway between 2 and 3.
