Answer:

  Solution: (2, 2)

Step-by-step explanation:

The first equation describes a line with a y-intercept of 3 and a (downward) slope of -1/2. That is, it has a "rise" of -1 for a "run" of 2.

__

The second equation describes a line with a y-intercept of -2 and an (upward) slope of 2. That is, it has a "rise" of 2 for a "run" of 1.

These two lines meet at the point (2, 2), which is the solution to the set of equation. Those are the values of x and y that satisfy both equations.

denpristay [2]

Answer:

3,524 corresponde al fraccionario \frac{3524}{1000}.

Step-by-step explanation:

La coma está desplazada tres espacios (3 dìgitos) hacia la izquierda del observador, el número decimal tiene su equivalente forma fraccionaria, en donde el numerador son todos los dìgitos en series y el denominado tiene la forma 10ⁿ, donde n es la cantidad de espacios que ha sido desplazada la coma. Entonces, 3,524 tiene la siguiente expresión:

3,524 = \frac{3524}{10^{3}}

3,524 = \frac{3524}{1000}

A store has a sale with 30% off every item. When you enter the store, you receive a coupon that states that you receive an addit
sergey [27]

Answer:

No, It is not equal to a 60% discount.

Step-by-step explanation:

Think of this. I go into a store and everything is 50% off and I have a coupon myself that is a 50% off discount for a specific item. It may seem like the item is now free, but it isn't. Imagine the item was $1 before any discount. Then the store took 50% off of the $1, leaving it at $0.50. So now with my discount of 50% off the item I will be taking this 50% off of $0.50 = my final discounted cost of $0.25.

Hope I helped you understand :)

A right triangle has a hypotenuse of 10 feet and a leg of 6 feet. What is the length of the other leg?
Artemon [7]

Answer:

The other length of the leg is <em>8 feet.</em>

Step-by-step explanation:

To find the answer we have to find what<em> 10</em> and <em>6 is squared.</em>  <em>10 x 10 = 100</em>.  

<em>6 x 6 = 36.  </em>Now since we are trying to find the length of the other leg, we will <em>subtract 100 from 36</em> and we get <em>64</em>.  Then for the last step, we will figure out what number<em> squared equals 64.</em>  Because 8 x 8 = 64, <em>8 is our answer.</em>
