Answer:
{x,y} = {25/9,23/9}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = -4y + 13
// Plug this in for variable x in equation [1]
[1] 5•(-4y+13) + 2y = 19
[1] - 18y = -46
// Solve equation [1] for the variable y
[1] 18y = 46
[1] y = 23/9
// By now we know this much :
x = -4y+13
y = 23/9
// Use the y value to solve for x
Answer:
You need a photo or text to back that up, we can't solve this without an image or something that explains this problem.
Step-by-step explanation:
The answer:
x = 1
Explanation:
If the line is parallel to the y-axis it has no slope, so you would only write down the x-intercept.
Area of road =70*50=3500
3500*2=7000 because it has cross road
6*6=36
7000-36=6964
6964*5.50=38302
Answer: 80
Write down all the values and cross out until you get to the middle, since there are 2 values, find the mean, which would be 80
