Answer:
Step-by-step explanation:
3w + 2c = 32
4w + 3c = 44
Multiply the 1st equation by 4 and 2nd equation by 3, we get:
12w + 8 c = 128
12w + 9 c = 132
Subtracting the top equation from the bottom equation, we get: c = 4
Substituting c = 4 in any one of the above equations and solving, we get: w = 8
Therefore, weight of 2w + 1c = 2(8) + 4 = 20 pounds (Answer)

Answer:
I'm going to use the following as an example.
To find the y-intercept, set x equal to 0 then solve for y.
two times zero is zero, so we have the following equation.
Solve for y
Your first point you will graph is (0, 2).
Now solve for the x intercept. To do this, set y = 0.
4(0) = 0, so you can remove it, and solve for x.
Now the next point you have is (4, 0). plot that point. Connect the two points with a line and you are done.
