Find a solution to the linear equation −2x−2y=8 by filling in the boxes with a valid value of x and y.Provide your answer below:

inna [77]

Given

$-2x-2y=8$

To find a solution for the linear equation, the first step is to write the equation in slope-intercept form:

-Pass the x-term to the right side of the equation by applying the opposite operation to both sides of the equal sign:

$\begin{gathered} -2x+2x-2y=8+2x \\ -2y=2x+8 \end{gathered}$

-Divide both sides by -2:

$\begin{gathered} \frac{-2y}{-2}=\frac{2x}{-2}+\frac{8}{-2} \\ y=-x-4 \end{gathered}$

Once you have expressed the equation of the line in slope-intercept form, replace it with any value for x and calculate the corresponding value of y, for example, x=2

$\begin{gathered} y=-(2)-4 \\ y=-2-4 \\ y=-6 \end{gathered}$

One solution for the linear equation is x=2 and y=-6, you can check the solution by replacing the values on the original equation, with both values the result should be 8:

$\begin{gathered} -2x-2y \\ -2\cdot2-2\cdot(-6) \\ -4+12=8 \end{gathered}$

As you can see the values are a valid solution for the linear equation.

So the solution is:

$-2(2)-2(-6)=8$

tatuchka [14]

To know the exact value of tan(157.5°), you only have to enter the value in your calculator:

First, press the buttton identified as "tan" and then write 157.5. The next step you must follow is press the button with the symbol of equal: "="

Now, the value of tan(157.5°) will appear on the screen of you calculator.

As you can see, the exact value of tan(157.5°) is:

tan(157.5°)=-0.4142

Simplify each expression. 3a^2b^-4/12a^-2b^-2, a=0, b=0

Maksim231197 [3]

Answer:

The answer is that 36a⁴/b² is 0.

Step-by-step explanation:

Let's simplify the expression given to us, this way:

3a^2b^-4/12a^-2b^-2

3a²b⁻⁴ ÷ 12a⁻²b⁻²

3a²/b⁴ ÷ 1/12a²b²

3a²/b⁴ * 12a²b²/1

36a⁴/b²

But let's recall that if a = 0 and b = 0, then we have:

36 * 0⁴ / 0² = 0

The answer is that 36a⁴/b² is 0.
