5x-2y=-3 -2x-y=-6 método de reducción suma y resta con procedimiento y respuesta doy corona a quien me ayude en menos de media h

maw [93]

Answer:

(1, 4)

Step-by-step explanation:

5x-2y=-3 -2x-y=-6 =>

5x-2y=-3

-2x-y=-6 Multiply all three terms by -2: 4x + 2y = 12

Then we have:

5x-2y=-3

4x + 2y = 12

---------------------

9x = 9 and so x = 1. Then, using -2x - y = -6, and substituting 1 for x:

-2(1) - y = -6, or

2 + y = 6, or

y = 4

Then the solution is (1, 4)

An investment is currently worth 1.035×108 dollars . Thirty years ago, the investment was worth 2.3×105 dollars. How many ti

nevsk [136]

The correct option is: B. 450

<u><em>Explanation</em></u>

Current value of the investment is $1.035\times 10^8$ dollars and 30 years ago, the value of the investment was $2.3\times 10^5$ dollars.

Suppose, the value of investment today is $n$ times greater than the value of the investment thirty years ago.

So, the equation will be........

$n(2.3\times 10^5)=1.035\times 10^8\\ \\ n= \frac{1.035\times 10^8}{2.3\times 10^5}=0.45\times 10^3 = 450$

Thus, the value of the investment today is 450 times greater than the value of the investment thirty years ago.
