Answer:

? = 45

Step-by-step explanation:

Since the triangles are similar, we can use proportions

20 20+8

------- = -------

? ? + 18

20 28

------- = -------

? ? + 18

Using cross products

20 ( ? +18) = = ? * 28

Distribute

20 ? + 360 = 28 ?

Subtract 20 ? from each side

360 = 8?

Divide each side by 8

360/8 = ?

45 = ?

-4 _> 4(6y-12)-2y

first distribute/ simplify the equation
-4 _> 24y-48-2y

then combine like terms
-4 _> 22y-48

solve for y

-4 _> 22y-48
44 _> 22y
2 _> y

so the answer is y <_ 2 ( y is less than or equal to 2)

Identify the slope of the line for the equation y= -2/3× + 1/3

natita [175]

Answer:

$\textbf{The slope of the parallel line is given by $ \frac{-2}{3} $}\\$

Step-by-step explanation:

$\textup{The slope of any two parallel lines are equal and they only differ in their $y- intercepts$. }\\\textup{Given $y = \frac{-2}{3}x + \frac{1}{3} $}\\\textup{This is comparable to $y = mx + c$, where $m$ is the slope of that line.}\\\textup{Therefore, the slope of the given line and any line parallel to it is $ \frac{-2}{3}$.}$
