The system has Infinitely many solutions.

Step-by-step explanation:

We need to find how many solutions are there in:

$-2x+3y=7\\ 2x-3y=-7$

Let:

$-2x+3y=7\,\,\,eq(1)\\ 2x-3y=-7\,\,\,eq(2)$

Adding eq(1) and eq(2)

$-2x+3y=7\\ 2x-3y=-7\\-------\\0=0$

Since a constant term is equal to constant term, so the system has Infinitely many solutions.

Answer:

A) 1/12 lb.

.. (1 2/3)/20 = 1/20 + (2/3)*(1/20)

.. = 1/20 + 1/30

.. = 3/60 + 2/60

If I paid 9.00$ for 4 lb of candy, how much candy I buy for 12.00$

sattari [20]

Answer:

5.33lb of candy

Step-by-step explanation:

First, you'd need to set up a proportion.

4 pounds x poinds

----------- = -------------

9 dollars 12 dollars

Then, cross multiply.

9x = 4(12)

9x = 48

x = 48/9

And your answer is x = 5.33!

Hope I helped! ☺

Find parametric equations for the path of a particle that moves along the circle x2 + (y − 3)2 = 16 in the manner described. (en

sveticcg [70]

Answer:

$x(t) = 4 cos(-t)\\y(t) = 4 sin(-t) + 3\\$

and t ∈ [0,2π]

Step-by-step explanation:

The standard equation for circle is:

$(x-h) ^2 + (y-k)^2 = r^2$

Comparing our equation with standard

$x^2 + (y-3)^2 =16$

h= 0,

k= 3

r= 4 (as in standard r², so r =√ r²)

Required:

Parametric equations of the circle

Formula:

$x = r cos(t) + h\\y= r cos(t) +k$

Putting values of r and h and k we get

$x= 4 cos(t) + 0 \\x= 4 cost(t) \\y= 4 sin(t) + 3$

As we need to start the object at (4,3)

x(0) = 4 and y(0) = 3

and the period is 2π

As the rotation is starting clock wise we will invert the value of t i.e -t

$x(t) = 4 cos(-t)\\y(t) = 4 sin(-t) + 3\\$

and t ∈ [0,2π]
