Need help what are the classifications of each system
ratelena [41]
You can graph them on Desmos, then use this attachment to find out the classification.

In the first system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.

In the second system, they're parallel lines with no solution, therefore the answer is inconsistent.

In the third system, they intersect and they have one solution, therefore the answer is consistent, independent.

In the fourth system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.

adoni [48]

Answer:

On the right is a circle with centre (0, 0), radius r and (x, y) any point on the circle. Distance between (0,0) and (x, y) equals the radius, r. If the centre is (0, 0), the equation of the circle will be of the form x2 + y2 = r2.

The formula d = rt can be used to calculate the distance (d) an object travels using its rate of speed (r) and the time it trave
riadik2000 [5.3K]
Start with d=rt. Now, solve for r by isolating it. since r is multiplied by t, divide both sides by t. d/t=r. So your answer would be the 2nd choice.

Lim x-&gt;-5(((1)/(5)+(1)/(x))/(10+2x))=<br><br>correct answer 1/10x = -1/50<br><br>explain:
slava [35]

Given:

The limit problem is:

lim_{x\to -5}\dfrac{\dfrac{1}{5}+\dfrac{1}{x}}{10+2x}

To find:

The value of the given limit problem.

Solution:

We have,

lim_{x\to -5}\dfrac{\dfrac{1}{5}+\dfrac{1}{x}}{10+2x}

It can be written as:

=lim_{x\to -5}\dfrac{\dfrac{x+5}{5x}}{2(5+x)}

=lim_{x\to -5}\dfrac{x+5}{5x}\times \dfrac{1}{2(5+x)}

=lim_{x\to -5}\dfrac{1}{5x\times 2}

=lim_{x\to -5}\dfrac{1}{10x}

Applying limit, we get

lim_{x\to -5}\dfrac{1}{10x}=\dfrac{1}{10(-5)}

lim_{x\to -5}\dfrac{1}{10x}=\dfrac{1}{-50}

Therefore, the value of given limit problem is -\dfrac{1}{50}.
