A statement or proposition which is regarded as being established, accepted, or self-evidently true
Standard form is ax+by=c
to find the slope, do, -a/b
-a/b=-3/2
-a=-3
b=2
a=3
3x+2y=c
find c
plot the point
(8,-12)
(x,y)
x=8
y=-12
3(8)+2(-12)=c
24-24=c
0=c
3x+2y=0 or
y=-3/2x
Answer:

Step-by-step explanation:
The percentage increase of the value of Tessa's stock is 21%.
<h3>Percentage increase</h3>
Using this formula
Percentage increase=Current stock worth-Old stock worth/Old stock worth

Answer:
arc = 7 pi
Step-by-step explanation:
The length of the arc is circumference
C = 2 * pi *r
C = 2 * pi *4
C = 8 pi
A circle is 360 degrees. The arc is 315 degrees
The arc is 315/360 of the circle, that is 7/8 of the circle, so it will be 7/8 of the circumference
7/8C = 7/8 (8pi)
arc = 7 pi
