First of all, let's find the slope of line L. To find the slope of a line, you write it in the explitic form 
, and consider the coefficient 
. So, we have
So, the slope of line L is 2/3.
Two lines are parallel if they have the same slope. So, line M has slope 2/3 as well, and we know that it passes through the point (3, -10).
When you are given the slope and a point 
of a line, its equation is given by
So, if you plug your values, you have
which you can simplify into
Answer:
Yes it is, but further be simplified as
P = 2(l+w)
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
x=0.5. by substitution we get 10(0.5)-4=5-4=1
Its 0.5793 with the bar over the 3
The first thing we must do for this case is to define variables:
w: pounds of meat
x: carton of milk
y: loaf of bread
z: cereal breakfast box
We write the system of equations:
0.70x + 0.60y + 0.50z + 1.50w = 10
x = 2y
z = y + 1
w = z
Solving the system we have:
w = 3
x = 4
y = 2
z = 3
Answer:
3 pounds of meat
4 cartons of milk
2 loaves of bread
3 boxes of breakfast cereal
