Answer:
Step-by-step explanation:
Given triangles are similar, so we setup a proportion
(140-x)/81 = x/9
solving gives x = 14
AC = 140-x = 140-14 = 126
Of course not.
-- Take a washable marker, and give your little sister another washable marker.
-- Stand back-to-back in your bedroom, you facing the front wall, and her facing the back wall.
-- When you say 'GO', both of you draw a straight line on the wall.
Then look at the lines.
-- The front and back walls are parallel planes, but it would be
amazing if the two lines are parallel. One could even be a
horizontal line and the other a vertical one . . . definitely not parallel.
Answer:
We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

Step-by-step explanation:
Incomplete question:
There is no point to complete the equation.
As we have no point to complete the linear equation, we will solve for any given point (x0,y0) and a slope of m=-2.
The linear equation can be written generically as:

If a point, like (x0,y0) belongs to the linear equation, it satisfies its equation. Then:

Then, we can calculate b as:

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

X+X+3xX+4 divided by X = F
Answer: y+1 = 5(x-1)
