Inverse variation:

y=\frac{k}{x}

k is a constant

Use the given information (when x=4 y=4) to find the value of the constant:

\begin{gathered} 4=\frac{k}{4} \\  \\ \text{Multiply both sides of the equation by 4:} \\ 4\times4=4\times\frac{k}{4} \\  \\ 16=k \\  \\  \\ k=16 \end{gathered}

Then, the given relationship has the next equation:

y=\frac{16}{x}

Use the equation above to find y when x=2:

\begin{gathered} y=\frac{16}{2} \\  \\ y=8 \end{gathered}Then, when x=2, y=8

6. Solve for x.<br> 10x - 4 = +(8x + 14)
Nuetrik [128]

Simplify brackets

10x - 4 = 8x + 14

Add 4 to both sides

10x = 8x + 14 + 4

Simplify 8x + 14 + 4 to 8x + 18

10x = 8x + 18

Subtract 8x from both sides

10x - 8x = 18

Simplify 10x - 8x to 2x

2x = 18

Divide both sides by 2

x = 18/2

Simplify 18/2 to 9

<u>x = 9</u>

Write an equation of the line in slope-intercept form (0,-2) ,(2,2)
Kipish [7]

Answer:

y=2x-2

Step-by-step explanation:

Slope intercept Formula: y=mx+b

y= Y coordinate

m = slope

x = x coordinate

b = y intercept

Point Slope Formula: y-y1=m(x-x1)

Slope Formula: m= y2-y1 / x2-x1

2 - (-2) / 2-0 = 4 / 2 = 2

y- (-2) = 2 (x - 0) = y+2=2x-0

y=2x-2

You are planning your week-end schedule. You can spend at most 8 hours playing video games and doing homework. You want to spend
MatroZZZ [7]

The system of inequalities is:

v + h ≤ 8

v < 2

h ≥ 1.5

<h3>Which system of equations represents this situation?</h3>

Let's define the variables:

  • v = number of hours playing video games.
  • h = number of hours spent on homework.

The maximum time that you can spend on both activities is 8 hours, then:

v + h ≤ 8

You want to spend less than 2 hours on video games, so:

v < 2

You want to spend at least, 1.5 hours on homework, so:

h ≥ 1.5

Then the system of inequalities is:

v + h ≤ 8

v < 2

h ≥ 1.5
