The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!
Answer:
3 workers
Step-by-step explanation:
just divide by 2
Simple...
you have: x-3y=18
You want to convert it into slope-intercept form or y=mx+b form-->>>
x-3y=18
Isolate the variable-->>
x-3y=18
-x -x
-3y=-x+18
Now simply divide...
y=
Thus, your answer.
The point-slope form:

m - slope
The formula of a slope:

We have the points (-2, 3) and (1, -3). Substitute:

The standard form: Ax + By = C. Convert:
<em>use distributive property</em>
<em>subtract 3 from both sides</em>
<em>add 2x to both sides</em>

Sinα=h/L where h=height, L=string length...
h=Lsinα so
h(25°)=50sin25≈21.1ft
h(45°)=50sin45≈35.4ft
