Let s = shirts
let t = ties
2s + t = 42
s + 2t = 39
s = 15
t = 12
one shirt equals $15
Answer:
y= 2x-2
Step-by-step explanation:
Use the linear equation.
y= mx+b
indentify what you already know
x= 2 and y= 2 and m(slope)= 2
we are solving for b, so lets plug in what we have.
2= 2(2)+b
Simplify.
2= 4+b
Subtract 4 from both sides.
-2= b
Rewrite your equation wihtout the x and y values.
y= 2x-2
Answer:
7,115.6
Step-by-step explanation:
6700+410+5.6=7,115.6
Answer:
area = (1/2)|Ax(By-Cy) +Bx(Cy-Ay) +Cx(Ay-By)|
= (1/2)|2(3-6) +3(6-1) +1(1-3)| = (1/2)|-6 +15 -2|
area = 7/2
