Answer:

Step-by-step explanation:

Some of the expressions that can be derived that have the values of 12 are:

i. 2a = 2 x 6

      = 12

ii. 3b = 3 x 4

        = 12

iii. (b  + c) x a = (4 - 2) x 6

                = 2 x 6

                = 12

iv. 2b + c^{2} = (2 x 4) + (-2 x -2)

                = 8 + 4

                = 12

v. b^{2} -  c^{2} = (4 x 4) - (-2 x -2)

             = 16 - 4

             = 12

vi. c^{4} - b = (-2 x -2 x -2 x -2) + 4

             = 16 - 4

             = 12

Write an equation in standard form using integers <br><br> Y= - x<br> —<br> 5
kykrilka [37]

Answer:

x + y = - 5

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y = - x - 5 ( add x to both sides )

x + y = - 5 ← in standard form

an angle measures 27.4 more than the measure of its complementary angle what is the measure of each angle
Arisa [49]

Hello!

<h2>31.3° and 58.7°</h2><h2></h2>

To solve, we can set up an algebraic expression.

Complementary angles add up to 90°, and in this instance, one angle is 27.4° more than the other. Therefore:

∠1 = x

∠2 = x + 27.4°

∠1 + ∠2 = 90°

x + (x + 27.4°) = 90°

Combine like terms:

2x + 27.4° = 90°

Subtract 27.4 from both sides:

2x = 62.6°

Divide both sides by 2:

x = 31.3°

Therefore, one of the angles is 31.3°. Solve for the measure of the other angle:

(31.3°) + 27.4° = 58.7°

Y=f(x)=(1/9)^x find f(x) when x=(1/2)
tatyana61 [14]

Answer:

\frac{1}{3}

Step-by-step explanation:

In this question, you would solve the for f(x) by plugging in the given value to x.

Solve:

\frac{1}{9}^\frac{1}{2}

Distribute the exponent to the numerator and denominator.

\frac{1^\frac{1}{2}}{9^\frac{1}{2}}

Simplify.

\\\\\frac{1^\frac{1}{2}}{9^\frac{1}{2}}\\\\9^\frac{1}{2}=3\\\\\frac{1^\frac{1}{2}}{3}}\\\\

Use the 1^a = 1\,\text{} rule for the numerator:

\frac{1}{3}

Your final answer would be \frac{1}{3}
