A store pays $365.84 for a fountain. The store marks up the price by 10%.

Ann [662]

Answer:

The store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

Step-by-step explanation:

Given that a store pays $ 365.84 for a fountain, and then the store marks up the price by 10%, to determine the amount of the mark-up the following calculation must be performed:

365.84 x 10/100 = X

3,658.4 / 100 = X

36,584 = X

36.584 + 365.84 = 402.424

Thus, the store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

What is the value of y in this system of equations: 3x + y = 9 y = –4x + 10 ?

Ahat [919]

<span>3x + y = 9 (I)
</span><span>y = –4x + 10 (II)
------------------------
</span> $\left \{ {{3x + y = 9 } \atop {y = -4x + 10 }} \right.$

Pass the incognito "4x" to the first term, changing the signal when changing sides.
<span>-------------------------
simplify by (-1)
</span> $\left \{ {{3x + y = 9.(-1)} \atop {4x + y = 10 }} \right.$ <span>

-------------------------
</span> $\left \{ {{- 3x - \diagup\!\!\!\!y =-9} \atop {4x + \diagup\!\!\!\!y = 10}} \right. 
$
<span>
-------------------------
</span> $\left \{ {{- 3x = - 9} \atop {4x = 10}} \right.$ <span>

-----------
</span> $\boxed{x = 1}$ <span><span>

</span></span><span>Substitute in equation (I) to find the value of "Y".

</span>3x + y = 9 (I)
3*(1) + y = 9
3 + y = 9
y = 9 - 3
$\boxed{y = 6}$

Answer:
$\boxed{\boxed{ \left \ {{x=1} \atop {y=6}} \right. }}$

Please answer thanks you (:

Answer:

B

Step-by-step explanation:

I believe it is B because it is the only one that doesnt have x values that repeat and give different answers.

Ex. For a, the x value in the first and third coords gives both 1 and 3 as answers.

Every x has to have a unique y value, so

(2,10) (3,12) is ok, but (2,10) (2,12) is not.

Sorry if this doesnt make sense haha

What set or sets of real numbers does -√16 belong to?

Sati [7]

Answer:

Step-by-step explanation:

Well the square root of 16 can be simplified to 4, which can be represented as a fraction: 4/1, so it's not irrational, but rather rational.

Whole numbers are similar to integers, and natural numbers, the only difference is integers includes all real numbers, which do not have a decimal value. So this includes negative numbers, zero, and positive numbers.

Whole numbers include all real numbers, which do not have a decimal value, and are greater than or equal to zero, or in other words, not negative.

Natural numbers include all real numbers, which do not have a decimal value, and are greater than zero, or in other words, positive numbers.

So this number is a integer, and rational number. (since the negative number in front of the radical)
