Answer:
b is (4,55). c is correct I believe.
Step-by-step explanation:
You need to find where the lines cross on the graph. You see that at point (4,55)
B. Multiplying both sides of the equation by 3
2x2x3=12 12x8=96 so the bale of hay weighs 96 pounds.
The solution to the systems of equations is (7, 3)
Given the systems of equations expressed as:
-x + 4y = 5 ....................1
x - 5y = -2 ...................... 2
Add both equations to have:
-x+x + 4y - 5y = 5 - 2
4y-5y = -3
-y = -3
y = 3
Substitute y = 3 into equation 1:
-x + 4(3) = 5
-x + 12 = 5
-x = 5 - 12
-x = -7
x = 7
Hence the solution to the systems of equations is (7, 3)
