Answer: $\left \{ {{2x+3y=7.20} \atop {4x+2y=8.80}} \right.$

Step-by-step explanation:

Let be "x" the price per pound for grapefruit, "y" the price per pound for oranges.

We know that Steve buys 2 pounds of grapefruit and 3 of oranges for $7.20.

This means that the sum of the products of $2x$ and $3y$ is $7.20. Then, we can write this equation to represent it:

$2x+3y=7.20$

Kennedy buys 4 pounds of grapefruit and 2 pounds of oranges for $8.80.

This means that the sum of the products of $4x$ and $2y$ is $8.80. Then, we can write this equation to represent this:

$4x+2y=8.80$

Therefore, we get that the system of equations that models the situation is:

$\left \{ {{2x+3y=7.20} \atop {4x+2y=8.80}} \right.$

What two positive real numbers whose product is 50 have the smallest possible sum?

Llana [10]

X * y = 50
y = 50 / x
S = x + y = x + 50 / x
S` = 1 - 50 / x²
1 - 50 / x² = 0
50 / x² = 1
x² = 50
x = √ 50 = 5 √2
y = 50 / 5√2 = 5 √2
Answer:
Those numbers are: x = 5√2 and y = 5√2.

Simplify radical -50

sesenic [268]

Answer:

$5i\sqrt{2}$

Step-by-step explanation:

If we want to convert $\sqrt{-50}$ into a radical simplified, we need to find two numbers that multiply to be -50 and one of them can be squared.

$\sqrt{-50} = \sqrt{-25 \cdot 2}$

The square root of -25 is 5i.

So:

$5i\sqrt{2}$
