Answer:
<em>- 3x + y = 22</em>
Step-by-step explanation:
<u>Equation of the line</u>
There are several forms to write the equation of a line.
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
The standard form of the equation of a line is:
Ax + By = C
We are given the slope m=3 and the point (-6,4). Substituting into the first equation:
y - 4 = 3 ( x + 6 )
Operating:
y - 4 = 3x + 18
Adding 4:
y = 3x + 18 + 4
Subtracting 3x, we get the standard form:
- 3x + y = 22
Answer:
l=102 feet, w=68 feet
Step-by-step explanation:
Let w=width and l=length
P=2l + 2w
And we know that w=2/3l
So, using substitution...
340=2l + 2(2/3l)
340=2l + 4/3l
340=6/3l + 4/3l
340=10/3l (now multiply both sides by 3 to get rid of fraction)
1020=10l
So l=102
Now plug in to get w
2(102)+2w=340
204+2w=340
2w=136
w=68
Now check:
2(102)+2(68)=
204+136=
340 It works!
X + x + 12 + x - 9 = 180
3x = 180 - 12 + 9
3x = 168 + 9
3x = 177
x = 59 degrees
Angle 1 = 59 degrees
Angle 2 = 59 + 12 = 71 degrees
Angle 3 = 59 - 9 = 50 degrees
