Which of the equations shown have infinitely many solutions?

2 answers:

8 0

The answer is D because if you distribute, you get: 3x-3=3x-3
And anything you plug in for X has the same solution on both sides of the equation

Answer:

Step-by-step explanation:

In order to have infinitely many solutions, the lines must be the same.

If we solve D by using the distributive property, we end up withe 3x-3=3x-3.

3x-3 and 3x-3 are the same lines and intersect infinitely many times, therefore the correct answer is D.

What is 3/5 + 1/2? As in fractions, I can’t figure it out!! :(

ella [17]

Step-by-step explanation:

$\frac{3}{5} + \frac{1}{2} \\ \\ = \frac{3 \times 2 + 1 \times 5}{5 \times 2} \\ \\ = \frac{6 + 5}{10} \\ \\ = \frac{11}{10} \\ \\ = 1 \frac{1}{10}$

Suppose z equals f (x comma y ), where x (u comma v )space equals space 2 u plus space v squared, y (u comma v )space equals spa

barxatty [35]

$z=f(x(u,v),y(u,v)),\begin{cases}x(u,v)=2u+v^2\\y(u,v)=3u-v\end{cases}$

We're given that $f_x(6,1)=3$ and $f_y(6,1)=-1$ , and want to find $\frac{\partial z}{\partial v}(1,2)$ .

By the chain rule, we have

$\dfrac{\partial z}{\partial v}=\dfrac{\partial z}{\partial x}\dfrac{\partial x}{\partial v}+\dfrac{\partial z}{\partial y}\dfrac{\partial y}{\partial v}$

and

$\dfrac{\partial x}{\partial v}=2v$

$\dfrac{\partial y}{\partial v}=-1$

Then

$\dfrac{\partial z}{\partial v}(1,2)=\dfrac{\partial z}{\partial x}(6,1)\dfrac{\partial x}{\partial v}(1,2)+\dfrac{\partial z}{\partial y}(6,1)\dfrac{\partial y}{\partial v}(1,2)$

(because the point $(x,y)=(6,1)$ corresponds to $(u,v)=(1,2)$ )

$\implies\dfrac{\partial z}{\partial v}(1,2)=3\cdot2\cdot2+(-1)\cdot(-1)=\boxed{13}$

Find the slope of the line that passes through the points<br> (-5,-6) and (5,10)

muminat

Answer:

8/5

Step-by-step explanation:

To find the slope given two points

m = (y2-y1)/(x2-x1)

= (10- -6)/(5 - -5)

= (10+6)(5+5)

= 16/10

= 8/5
