You solve an expression for a variable if that variable sits alone on one side of the equation, and everything else is on the other side.
So, our goal is to leave
alone on the right hand side, and move everything else to the left.
So, we start with

We multiply both sides by 3:

We divide both sides by 

To compute the required height, simply plug in the values:

Answer:
- y -3 = -4(x -0) or y -3 = -4x
- y = -4x +3
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
Fill in the given values:
y -3 = -4(x -0) . . . . point-slope form of the equation of the line
__
To get this to slope-intercept form, you want to rearrange it to ...
y = mx + b
Eliminating parentheses get you ...
y -3 = -4x
Adding 3 puts the equation in the desired form:
y = -4x +3
4+5x+x+2= 180
29
4+5(29)=149degrees
(29)+2= 31 degrees
i hope this helps
Simple multiplication. 35 x 20 = 700.
