Answer:

x^2 +25 + 2 = 2x^2 + 30

X^2 + 27 = 2X^2 + 30

       - 27              - 27

X^2 = 2X^2 + 3

-X^2 = 3

<em><u>X = SQRT. - 3</u></em>

Answer:

± sqrt(3) i =x

Step-by-step explanation:

x^2 +25 + 2 = 2x^2 + 30

Combine like terms

x^2 + 27 = 2x^2 +30

Subtract x^2 from each side

x^2 + 27 - x^2 = 2x^2 - x^2 +30

27 = x^2 +30

Subtract 30

27-30 = x^2

-3 = x^2

Taking the square root of each side

±sqrt(-3) = sqrt(x^2)

±sqrt(-3) =x

±sqrt(-1) sqrt(3) =x

We know the square root of -1 = i

± sqrt(3)i =x

You are making identical gift bags using 12 crayons and 28 bottles of bubbles. What is the greatest number of gift bags you can
const2013 [10]
Since you don't want any leftover items, you have to find the greatest common factor (GCF) of both the crayons and bubbles. Since the highest common factor for both 28 and 12 is 4, the greatest number of gift bags you can make without any leftover items would be 4 gift bags.

Hope I could help.

If g(x) = {(4, -5), (-3, 2), (-6, 1), (1,0)}, which set of ordered pairs represents
Ket [755]

Answer:

The inverse of g(x) is {(-5, 4), (2, -3), (1, -6), (0, 1)} ⇒ (A)

Step-by-step explanation:

To find the inverse of a function switch x and y

<u>Example:</u>

If f(x) = {(1, 2), (-4, 5), (0, 0)}

To find its inverse switch x and y in each ordered pair

The inverse of f(x) = {(2, 1), (5, -4), (0, 0)}

<em>Let us do the same with our question</em>

∵ g(x) = {(4, -5), (-3, 2), (-6, 1), (1, 0)}

→ Switch x and y coordinates in all ordered pair

∴ The inverse of g(x) = {(-5, 4), (2, -3), (1, -6), (0, 1)}

<em>Look at the answer to find the correct choice</em>

It is (A)
